With a VPN, all network traffic (data, voice, and video) goes through a secure virtual tunnel between the host device (client) and the VPN provider’s servers, and is encrypted. VPN technology uses a combination of features such as encryption, tunneling protocols, data encapsulation, and certified connections to provide you with a secure connection to private networks and to protect your identity. VPN connections technically give you all the benefits of a Local Area Network (LAN), which is similar to that found in many offices but without requiring a hard-wired connection. Early VPNs were often set up to give individual employees secure remote access to their company networks, hence the name “virtual private network”. By connecting to the company’s netwo...

The virus contained a Word document labeled List.DOC as an attachment to an email allowing access to porn sites. The email was first distributed to a Usenet group but quickly got out of hand. When a user opened the email a message, the infected Word attachment was sent to the first 50 names in the user's address book. The scheme was particularly successful because the email bore the name of someone the recipient knew and referenced a document they had allegedly requested. I recall spending long hours cleaning up after this one. 2.  The Anna Kournikova Virus This computer virus was attributed to a Dutch programmer Jan de Wit on February 11, 2001.
