How to Detect and Prevent Unauthorized Access to Your PC: 4 Effective Methods

Do you have a feeling that someone has been using your PC without your permission? Maybe you noticed some changes in your settings, files, or browser history. Or maybe you just have a gut instinct that something is not right.

If you suspect that someone has been snooping on your PC, you need to act fast and find out the truth. Unauthorized access to your PC can compromise your privacy, security, and data. You don’t want anyone to see your personal or work-related information, or worse, steal or delete it.

Fortunately, there are ways to detect and prevent unauthorized access to your PC. In this blog post, we will show you four effective methods to check if someone was snooping on your PC, and how to stop them from doing it again.

Method 1: Check Your Recent Files and Folders

One of the easiest ways to check if someone was snooping on your PC is to look at your recent files and folders. Windows 10 keeps track of what you have opened, modified, or deleted recently, and you can access this information from the File Explorer.

To do this, follow these steps:

• Open the File Explorer by clicking on the folder icon on the taskbar, or by pressing Windows key + E.
• On the left pane, click on Quick Access. You will see a list of recent files and folders under the Frequent folders and Recent files sections.
• Look for any files or folders that you don’t recognize, or that you didn’t open or modify yourself. If you find any, it could be a sign that someone else has been using your PC.

You can also check the recent files and folders for specific applications, such as Microsoft Word, Excel, PowerPoint, etc. To do this, open the application and click on the File tab. You will see a list of recent documents under the Open section. Look for any documents that you don’t recognize, or that you didn’t open or edit yourself.

However, this method is not foolproof, as someone could have deleted the recent files and folders history to cover their tracks. To prevent this, you can disable the option to clear the recent files and folders history in Windows 10. To do this, follow these steps:

• Open the Settings app by clicking on the gear icon on the Start menu, or by pressing Windows key + I.
• Click on Personalization, then click on Start on the left pane.
• Under the Show recently opened items in Jump Lists on Start or the taskbar section, turn off the toggle switch.

This will prevent anyone from clearing the recent files and folders history, and you will be able to see what has been opened or modified on your PC.

Method 2: Check Your Browser History

Another way to check if someone was snooping on your PC is to check your browser history. Your browser history shows the websites that you have visited, the searches that you have made, and the downloads that you have done. If someone has been using your PC, they might have used your browser to access the internet, and left some traces behind.

To check your browser history, follow these steps:

• Open your browser of choice, such as Google Chrome, Microsoft Edge, Mozilla Firefox, etc.
• Press Ctrl + H to open the history panel. You will see a list of websites that you have visited, organized by date and time.
• Look for any websites that you don’t recognize, or that you didn’t visit yourself. If you find any, it could be a sign that someone else has been using your PC.

You can also check the search history, download history, and cookies and cache of your browser, as they might contain more information about the online activity of the person who used your PC. To do this, follow these steps:

• Open your browser of choice, and press Ctrl + H to open the history panel.
• Click on the menu icon (three horizontal lines or dots) on the top right corner of the panel, and select the option that you want to check, such as Search history, Download history, Cookies and site data, etc.
• Look for any items that you don’t recognize, or that you didn’t create or download yourself.

However, this method is also not foolproof, as someone could have cleared the browser history to cover their tracks. To prevent this, you can disable the option to clear the browser history in your browser settings. To do this, follow these steps:

• Open your browser of choice, and click on the menu icon (three horizontal lines or dots) on the top right corner of the window.
• Select Settings, then click on Privacy and security on the left pane.
• Under the Clear browsing data section, click on the Choose what to clear every time you close the browser option.
• Uncheck the boxes for the items that you want to keep, such as Browsing history, Download history, Cookies and site data, etc.

This will prevent anyone from clearing the browser history, and you will be able to see what websites have been visited on your PC.

Method 3: Check Your Logon Events

Another way to check if someone was snooping on your PC is to check your logon events. Logon events are records of when someone logs on or off your PC, or when someone unlocks or locks your PC. By checking your logon events, you can see when your PC was used, and by whom.

To check your logon events, follow these steps:

• Press Windows key + R to open the Run dialog box.
• Type eventvwr.msc and press Enter to open the Event Viewer.
• On the left pane, expand Windows Logs, then click on Security.
• On the right pane, click on Filter Current Log.
• On the Filter tab, under the Event sources section, select Microsoft-Windows-Security-Auditing from the drop-down menu.
• Under the Event IDs section, type 4624, 4625, 4634, 4800, 4801, and press Enter. These are the event IDs for successful logon, failed logon, logoff, workstation lock, and workstation unlock, respectively.
• Click on OK to apply the filter.
• You will see a list of logon events on the middle pane, with the date and time, event ID, and user name. Look for any logon events that you don’t recognize, or that occurred when you were not using your PC. If you find any, it could be a sign that someone else has been using your PC.

You can also double-click on any logon event to see more details, such as the logon type, logon process, logon session, and source network address. These details can help you identify the method and location of the logon.

However, this method is only available for Windows 10 Pro users, as Windows 10 Home users do not have the option to enable logon auditing. To enable logon auditing on Windows 10 Pro, follow these steps:

• Press Windows key + R to open the Run dialog box.
• Type gpedit.msc and press Enter to open the Local Group Policy Editor.
• On the left pane, navigate to Computer Configuration > Windows Settings > Security Settings > Local Policies > Audit Policy.
• On the right pane, double-click on Audit logon events.
• On the Audit logon events properties window, check the boxes for Success and Failure under the Audit these attempts section.
• Click on Apply, then click on OK.

This will enable logon auditing on your PC, and you will be able to see the logon events in the Event Viewer.

Method 4: Use a Third-Party Software

Another way to check if someone was snooping on your PC is to use a third-party software that can monitor and record the activity on your PC. There are many software available that can do this, such as Prey, ActivTrak, SpyAgent, etc. These software can capture screenshots, keystrokes, web history, file changes, and more, and send them to your email or cloud account. You can use these software to see what someone has been doing on your PC, and who they are.

To use a third-party software, follow these steps:

• Research and select a reliable and reputable software that can monitor and record the activity on your PC. Look for software that offer features such as stealth mode, remote access, email alerts, and encryption.
• Download and install the software on your PC, and follow the instructions to set it up. You will need to create an account, configure the settings, and choose the items that you want to monitor and record.
• Run the software in the background, and wait for it to collect the data. You can access the data from your email or cloud account, or from another device that has the software installed.
• Look for any evidence of unauthorized access to your PC, such as screenshots, keystrokes, web history, file changes, etc.

However, this method is not recommended, as it can violate the privacy and security of other users, and may be illegal in some jurisdictions. You should only use this method if you have a valid reason and permission to do so, and if you are aware of the risks and consequences involved.

Conclusion

Unauthorized access to your PC can be a serious threat to your privacy, security, and data. You need to be vigilant and proactive in detecting and preventing it. By using the methods above, you can check if someone was snooping on your PC, and how to stop them from doing it again.

You should also take some preventive measures to protect your PC from unauthorized access, such as:

• Lock your PC with a strong password or PIN, and change it regularly.
• Use a biometric authentication method, such as fingerprint or face recognition.

How to Use a Fake IP Address and Mask Yourself Online

Do you want to browse the web anonymously and protect your privacy online? Do you want to access geo-restricted content and bypass censorship? Do you want to avoid online tracking and surveillance? If you answered yes to any of these questions, then you might be interested in learning how to use a fake IP address and mask yourself online.

An IP address is a unique identifier that is assigned to every device connected to the internet. It acts like a digital address that allows devices to communicate and exchange data over the network. However, your IP address can also reveal information about your location, identity, and online activity. This can pose a risk to your online security and privacy, especially if you are using a public or unsecured network.

Fortunately, there are methods available to hide your real IP address and replace it with a fake one. This way, you can mask your online identity and location, and make it appear as if you are accessing the internet from a different region or country. In this blog post, we will explore two of the most common and effective methods to use a fake IP address and mask yourself online: using a proxy server and using a virtual private network (VPN).

Using a Proxy Server

A proxy server is an intermediary server that acts as a bridge between your device and the websites you visit. When you use a proxy server, your web traffic is routed through the proxy server, and the proxy server’s IP address is displayed instead of your own. This way, you can mask your real IP address and access websites that are blocked or restricted in your region.

To use a proxy server, you need to do the following steps:

• Research and select a reliable proxy server provider. Look for reputable proxy server providers that offer secure connections and a wide range of server locations. You can use tools like [Hashtagify] or [RiteTag] to find popular and trending hashtags in your industry or topic.
• Configure your device’s proxy settings. Once you’ve chosen a proxy server, access your device’s network settings and input the proxy server’s IP address and port number.
• Test your connection. Visit a website that displays your IP address and verify that it reflects the IP address of the proxy server. This indicates that your real IP address is masked.

However, using a proxy server also has some drawbacks and limitations. For instance, proxy servers are usually unencrypted, which means that your web traffic can still be intercepted and monitored by third parties, such as your internet service provider (ISP), government agencies, or hackers. Moreover, some websites can still detect and block proxy servers, or use techniques like JavaScript and Flash to reveal your real IP address. Therefore, using a proxy server alone may not provide enough online anonymity and security.

Using a Virtual Private Network (VPN)

A virtual private network (VPN) is a service that creates a secure and encrypted tunnel between your device and a remote server. When you use a VPN, your web traffic is encrypted and routed through the VPN server, and the VPN server’s IP address is displayed instead of your own. This way, you can mask your real IP address and access websites that are blocked or restricted in your region.

To use a VPN, you need to do the following steps:

• Choose a reputable VPN provider. Research and select a VPN provider that prioritizes user privacy, has a strict no-logs policy, and offers a wide network of servers. You can check out our reviews of the [best VPN services] for more information and recommendations.
• Install the VPN application. Download and install the VPN application compatible with your device’s operating system.
• Launch the VPN application. Open the VPN application and log in using your credentials. Select a server location you want to connect to.
• Connect to the VPN server. Click the connect button to establish a secure connection through the VPN server.

Using a VPN has many advantages over using a proxy server. For example, VPNs provide end-to-end encryption, which means that your web traffic is protected from prying eyes and hackers. VPNs also have a higher success rate in bypassing geo-restrictions and censorship, as they can disguise your IP address more effectively. VPNs can also improve your online performance, as they can prevent bandwidth throttling and speed up your connection.

However, using a VPN also has some challenges and risks. For instance, VPNs can slow down your connection speed, as they add an extra layer of encryption and routing. VPNs can also be expensive, as they usually require a monthly or yearly subscription fee. Moreover, VPNs can be blocked or banned by some websites or countries, as they can violate their terms of service or laws. Therefore, using a VPN requires careful research and selection, as well as compliance with the rules and regulations of the websites and regions you visit.

Other Considerations for Online Anonymity

Using a fake IP address and masking yourself online can provide many benefits and opportunities, but it is not a foolproof solution. There are other factors and variables that can affect your online anonymity and security, such as:

• Your browser settings and history. Your browser can store and reveal information about your online activity, such as your browsing history, cookies, cache, and autofill data. To prevent this, you can use a private or incognito mode, or clear your browser data regularly.
• Your online behavior and habits. Your online behavior and habits can also expose your identity and location, such as your social media profiles, online accounts, email addresses, and passwords. To avoid this, you can use different usernames and passwords for different websites, or use a password manager to generate and store strong and unique passwords.
• Your device settings and features. Your device settings and features can also compromise your online anonymity and security, such as your GPS, Bluetooth, Wi-Fi, microphone, and camera. To prevent this, you can disable or limit these settings and features when you are not using them, or use a firewall or antivirus software to protect your device from malware and cyberattacks.

Conclusion

Using a fake IP address and mask yourself online can be a useful and effective method to enhance your online privacy and security. However, it is not a magic bullet that can solve all your online problems. You need to be aware of the pros and cons of each method, and choose the one that suits your needs and preferences. You also need to be mindful of the other factors and variables that can affect your online anonymity and security, and take the necessary precautions and measures to safeguard your online identity and location. Remember, your online security and privacy are your responsibility, and you should always use the internet with caution and respect.

What are Red Rooms.? Do they really Exist in the Dark/Deep Web. ?

Red Rooms are basically one of the darkest places on the deep web. It basically charge money in bitcoins for viewing unimaginable videos like murders, rapes etc...

‘Red Room’ sites, the story goes, are darkweb sites where users pay thousands – or tens of thousands – to watch rapes and murders live. Urban legends about the existence of ‘Red Rooms’ have circulated for years – but as yet, there’s no evidence that they exist. If ‘Pay per View’ torture sites do exist, it’s almost certain that they don’t work via Tor (the software used to access dark web sites) – which is too slow to stream video live. The term ‘Red Room’ has been around on the internet for more than  decade – thought to originate either from ‘red rum’/’murder’, or from the 1983 horror film Videodrome, where torture is shown live on satellite TV in a red-painted room.

The video Daisy’s Destruction – widely discussed on forums and on Reddit – is not actually a snuff film, but features horrifying abuse and sexual assault of a young child. It was streamed on so-called ‘Hurtcore’ paedophile sites – where paedophiles watch torture and abuse of children and babies. Its creator, Peter Scully, is in jail in the Philippines. The video called ‘Daisy’s Destruction’ showed the baby girl being tied upside down by her feet, sexually assaulted and beaten by Scully and a masked woman.

In the series of videos, she is whipped and assaulted with sex toys by Peter Scully’s girlfriend – who he met when she herself was a child prostitute. According to the Sydney Morning Herald, the footage was so horrific police called it ‘the worst we have encountered in our years campaigning against child pornography.’ Reports that the video feature ‘Daisy’ being killed are inaccurate – while human remains were discovered at one of Peter Scully’s homes, the girl from the film was rescued alive. The videos were streamed via a paedophile website which hosted torture videos, called Hurt 2 The Core – which boasted 15,000 videos downloads daily. The worst paedophiles – those who uploaded their own material – gained access to a Producer’s Lounge, with the most offensive material.

What is Cookie Stuffing and Ad Fraud Scheme ? || techtalksgroup ||

Cookie Stuffing, also known as Cookie Dropping, is one of the most popular types of fraud schemes in which a website or a browser extension drops handfuls affiliate cookies into users' web browser without their permission or knowledge.


This type of SIVT involves inserting, deleting, or misattributing cookies to manipulate or falsify the prior activity of users. Also known as ‘cookie dropping,’ it pertains to the fraudulent manipulation of visitor cookies to disguise or conceal legitimate user cookies.

Often considered a black hat online marketing technique, cookie stuffing can potentially generate fraudulent affiliate income for the cookie stuffer by overwriting legitimate affiliate cookies. A website visitor may unknowingly receive a third-party cookie from a website unrelated to the one actually visited. Later on, if the visitor goes to a targeted website and completes a qualifying transaction or makes a purchase, the cookie stuffer illegally earns a commission from the targeted site and deprives the legitimate affiliate of its referral commission.

What are Rootkits..?? || techtalksgroup ||

What Is a Rootkit?

A rootkit is a clandestine computer program designed to provide continued privileged access to a computer while actively hiding its presence. The term rootkit is a connection of the two words "root" and "kit." Originally, a rootkit was a collection of tools that enabled administrator-level access to a computer or network. Root refers to the Admin account on Unix and Linux systems, and kit refers to the software components that implement the tool. Today rootkits are generally associated with malware – such as Trojans, worms, viruses – that conceal their existence and actions from users and other system processes.

What Can a Rootkit Do?

A rootkit allows someone to maintain command and control over a computer without the computer user/owner knowing about it. Once a rootkit has been installed, the controller of the rootkit has the ability to remotely execute files and change system configurations on the host machine. A rootkit on an infected computer can also access log files and spy on the legitimate computer owner’s usage.

Rootkit Detection

It is difficult to detect rootkits. There are no commercial products available that can find and remove all known and unknown rootkits. There are various ways to look for a rootkit on an infected machine. Detection methods include behavioral-based methods (e.g., looking for strange behavior on a computer system), signature scanning and memory dump analysis. Often, the only option to remove a rootkit is to completely rebuild the compromised system.

Rootkit Protection

Many rootkits penetrate computer systems by piggybacking with software you trust or with a virus. You can safeguard your system from rootkits by ensuring it is kept patched against known vulnerabilities. This includes patches of your OS, applications and up-to-date virus definitions. Don't accept files or open email file attachments from unknown sources. Be careful when installing software and carefully read the end-user license agreements.

Static analysis can detect backdoors and other malicious insertions such as rootkits. Enterprise developers as well as IT departments buying ready-made software can scan their applications to detect threats including "special" and "hidden-credential" backdoors.

New Zero-Day Vulnerability Found Effecting All Versions of Windows || techtalksgroup ||

A security researcher has publicly disclosed an unpatched zero-day vulnerability in all supported versions of Microsoft Windows operating system (including server editions) after the company failed to patch a responsibly disclosed bug within the 120-days deadline.

Discovered by Lucas Leong of the Trend Micro Security Research team, the zero-day vulnerability resides in Microsoft Jet Database Engine that could allow an attacker to remotely execute malicious code on any vulnerable Windows computer.

The Microsoft JET Database Engine, or simply JET (Joint Engine Technology), is a database engine integrated within several Microsoft products, including Microsoft Access and Visual Basic.

According to the an advisory released by Zero Day Initiative (ZDI), the vulnerability is due to a problem with the management of indexes in the Jet database engine that, if exploited successfully, can cause an out-out-bounds memory write, leading to remote code execution.
An attacker must convince a targeted user into opening a specially crafted JET database file in order to exploit this vulnerability and remotely execute malicious code on a targeted vulnerable Windows computer.

"Crafted data in a database file can trigger a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code under the context of the current process," Trend Micro's Zero Day Initiative wrote in its blog post.
"Various applications use this database format. An attacker using this would be able to execute code at the level of the current process."

According to the ZDI researchers, the vulnerability exists in all supported Windows versions, including Windows 10, Windows 8.1, Windows 7, and Windows Server Edition 2008 to 2016.

ZDI reported the vulnerability to Microsoft on May 8, and the tech giant confirmed the bug on 14 May, but failed to patch the vulnerability and release an update within a 120-day (4 months) deadline, making ZDI go public with the vulnerability details.
Proof-of-concept exploit code for the vulnerability has also been published by the Trend Micro its GitHub page.Microsoft is working on a patch for the vulnerability, and since it was not included in September Patch Tuesday, you can expect the fix in Microsoft's October patch release.
Trend Micro recommends all affected users to "restrict interaction with the application to trusted files," as a mitigation until Microsoft comes up with a patch.

Top 5 Kali Linux Tools Every Hacker Should Know All About |techtalksgroup|

Top Kali Linux Tools:-
Now let’s get started with the list of my favorite tools and a lot of other hackers favorite tools too.

1. Metasploit:-

Metasploit is a framework for developing exploits, shellcodes, fuzzing tool, payloads etc. And it has a very vast collection of exploits and exploitation tools bundled into this single framework. It is available for all major Operating Sytems out there Windows, OS X, and Linux and comes pre-installed in Kali Linux. It is an offensive tool and to attack your own or your company’s infrastructure to check for security loopholes and to fix them before an actual attacker can break in.
It can also be used to target web applications, networks, and servers etc. You get both GUI and command line interface. There are to products for Metasploit a Free Community version and a paid Metasploit Pro.

2. Nmap (Network Mapper):-

Nmap is used to scan whole networks for open ports and for mapping networks and a lot more things. It is mainly used for scanning networks and discover the online PC’s and for security auditing. Most of the network admins use Nmap to discover online computer’s, open ports and manage services running. It uses raw IP packets in such a creative way to know what hosts are available on the network and what ports are open which services (applications name and version) are running on those systems.
It comes into version GUI and Command Line. Zenmap is the GUI version what I recommend is that first learn the command line and then move on to the GUI if you feel confident.

3. Armitage:-

Armitage is a graphical cyber attack management tool and it provides a GUI interface for all Metasploit features and makes it easier to understand and use. If you really want to understand and grow into the advanced features then Armitage is a great choice for you.

Armitage organizes Metasploit’s capabilities around the hacking process. There are features for discovery, access, post-exploitation, and maneuver.

And if you are working in a team then it can be a real help to share information with your team:

• Use the same sessions.
• Share victim hosts, capture data, download files etc.
• Communicate using a shared event log.
• Run bots to automate the tasks.

4. John The Ripper (JTR):-

John The Ripper is a very popular tool for password cracking it is also known as JTR and also it has the coolest name of all the tools. Mostly it is simply referred as ‘Jhon’ it is the most commonly used tool for password cracking and to perform dictionary attacks. John The Ripper takes text files, referred as a ‘wordlist’, which contains the list of commonly used passwords or real passwords cracked before, and it encrypts the password in the wordlist in the same way as the password which is being cracked. And then compare the output string with the encrypted string of the provided password.

This tool can be used to perform different types of dictionary attacks. If you are confused between Jhon The Ripper and THC Hydra then the most simple way to explain it is that THC Hydra is used to crack a password for online services and Jhon The Ripper is used for offline password cracking.

5. Wireshark:-

Wireshark is an open source tool for network analysis and profiling network traffic and packets and this kind of tools are referred to as Network Sniffers.

Wireshark, previously known as Ethereal, is used to monitor network traffic and analyze the packets that are sent out. Wireshark can intercept network traffic ranging from connection level information to bits of the information which make up a signal packet. All of this is done in real time and show to the user in a readable format. There are a lot of developments made in the tool (platform) over the years and it includes filters, color-coding the packets depending on their information and these features really help the penetration testers to dig deeper in the network traffic and inspect the packets in detail.

Note: If you are really interested in Network administration and penetration testing then knowing how to use Wireshark is a required skill. There are a lot of resources available online from where you can learn about using Wireshark in depth.

UK’s Critical Infrastructure Vulnerable To DDoS Attacks ||tech talks group||

According to data revealed under the Freedom of Information Act by Corero Network Security, over one-third of critical infrastructure organizations in the UK are vulnerable to DDoS attacks. As per Corero, 39 percent of companies have ignored the risk of attacks on their network, leaving themselves vulnerable to data breaches, malware, and ransomware.

In a statement issued today, Sean Newman, director of product management at Corero, comments: “Cyber-attacks against national infrastructure have the potential to inflict significant, real-life disruption and prevent access to critical services that are vital to the functioning of our economy and society. These findings suggest that many such organizations are not as cyber resilient as they should be, in the face of growing and sophisticated cyber threats.”

Newman adds, “By not detecting and investigating these short, surgical, DDoS attacks on their networks, infrastructure organizations could also be leaving their doors wide-open for malware or ransomware attacks, data theft or more serious cyber attacks.”

Under the UK government’s proposals to implement the EU’s Network and Information Systems (NIS) directive, these organizations could be liable for fines of up to £17 million, or four percent of global turnover.

David Emm, the principal security researcher at Kaspersky Lab said, “The world isn’t ready for cyber-threats against critical infrastructure – but criminals are clearly ready and able to launch attacks on these facilities. We’ve seen attempts on power grids, oil refineries, steel plants, financial infrastructure, seaports and hospitals – and these are cases where organizations have spotted attacks and acknowledged them. However, many more companies do neither, and the lack of reporting these incidents hampers risk assessment and response to the threat.”

Edgard Capdevielle, CEO of Nozomi Networks, also commented: “This report emphasizes the impact of DDoS attacks and how they are often used as a cover to distract security teams while infecting systems with malware or stealing data. Such initiatives are often the first step in “low and slow”. He further added that “In light of this information, CNI organizations should give a high priority to re-assessing their cyber-security programs, evaluate where they are in relation to government recommendations, and inform themselves about current technologies available for protection….The right approach is to both shore up defenses and be able to quickly respond when attacks do occur.”

Targeting CNI, Eldon Sprickerhoff, founder and chief security strategist at entire said, “Although cyber-security regulations will require significant effort for the companies that are affected, this new legislation by the UK government demonstrates that they understand the severity of cyber-threats in today’s digital world and the destruction they can cause, if undeterred. Even if you’re not a CNI, cyber-threats should concern you. With cyber-criminals constantly adjusting their tactics, it is imperative that companies never stop defending themselves by constantly improving and expanding their cyber-security practices. Managed detection and response and incident response planning are common ways companies can stay ahead of their attackers.”

Here are five tips to help you can stay ahead of cybercriminals: 

• Encryption – store sensitive data that is only readable with a digital key
• Integrity checks – regularly check for any changes to system files
• Network monitoring – use tools to help you detect for suspicious behavior
• Penetration testing – conduct controlled cyber-attacks on systems to test their defenses and identify vulnerabilities
• Education – train your employees in cyber-security awareness and tightly manage access to any confidential information

Top 3 Data Destruction Softwares. Check it Out....!!! || tech talks group ||

Data destruction software, sometimes called data sanitization software, disk wipe software, or hard drive eraser software, is a software-based method of completely erasing the data from a hard drive.

When you delete files and then empty the Recycle Bin, you don't actually erase the information, you just delete the reference to it so that the operating system can't find it. All the data is still there and, unless it's overwritten, can be easily recovered using file recovery software.

Data destruction software, however, truly does erase the data. Each data destruction program utilizes one or more data sanitization methods that can permanently overwrite the information on the drive.

If you need to remove all traces of a virus or you're planning on recycling or disposing of your hard drive or computer, wiping your hard drive using data destruction software is the best way to protect yourself.

Note:   

Data destruction software is just one of several ways to completely erase a hard drive. Also, if a complete hard drive wipe isn't what you're after, check out our free file shredder software list for programs better suited for individual file destruction.

Darik's Boot and Nuke (DBAN)

Darik's Boot and Nuke (DBAN) is a self-contained boot image that securely wipes  the hard disks of most computers. DBAN is appropriate for bulk data destruction.
DBAN will automatically delete the contents of any detected hard disk, which is why it is an appropriate utility for bulk or emergency data destruction. In order to install DBAN, you need to burn the file to a blank disc and boot the computer with it.
DBAN is a good way to ensure your data is erased from any hard drive when you are recycling your PC. If you are thinking of selling your PC, then DBAN is another way of preventing identity theft, and a good way to totally clean a Microsoft Windows installation of viruses, malware, and spyware.
DBAN can prevent or hinder all known techniques of hard disk forensic analysis. Basically, this means it writes over the existing data, making it virtually impossible to recover the previous data.
DBAN has been designed for the home user, and although it is good at what it does, the interface is a little clunky to get to grips with. Unless you are used to using similar applications and are familiar with file systems, DBAN may not be the choice for you.

CBL Data Shredder

Data Shredder (also known as CBL Data Shredder) is a data destruction utility designed to securely erase a hard disk or digital storage device, completely removing the data and making it unrecoverable. The software utilizes the Gutmann method[1] of destroying data rather than other means of data destruction (such as: ATA secure erase, crypto-shredding, degaussing, physical destruction). While Data Shredder is a mature release (2007), due to its effectiveness and ease of use the software utility was still listed as a Top Key Player in the Data Destruction market by Business .

MHDD

MHDD is the most popular freeware program for low-level HDD diagnostics.

MHDD supports these interfaces: IDE, Serial ATA, SCSI. Also there is a possibility to access an USB storage, there are drivers for emulation (USB->SCSI).

This software can make precise diagnostic of the mechanical part of a drive, view SMART attributes, perform Low-level format, bad sector repair, different tests and tens of other functions.

MHDD is the small and powerful freeware tool to work with hard drives at the lowest possible level. First version was released in 2000 by me, Dmitry Postrigan. It was able to make surface scan of an IDE drive in CHS mode. My main objective was to develop well-known and trusted HDD diagnostic tool.

Now MHDD is much more than just diagnostic. You can do anything with MHDD: diagnose your drive, access raw sectors, manage S.M.A.R.T. (SMART) and other drive parameters such as acoustic management, security, Host Protected Area. You can even send your own commands to a drive using very simple linear scripting engine.
