BANGALORE, INDIA: It comes in many forms. In the form of a love letter, a sexy image of tennis star Anna Kournikova or any other subject that arouses your voyeuristic tendencies. That is the world of computer virus that spread in the speed of light, or even faster.

With the advent of social networking sites, the threat of viruses has also increased manifold. If it was the worm Koobface that hit networking site Facebook recently, the latest one is in the form of a more seductive one – a subject line that promises to take you to the video clipping of a striptease party.

If you get a mail with a similar subject, don't open it says Websense Security Labs, because it contains malicious links and striptease beauty may make your computer dance according to the tune of the fraudsters.

Websense, which discovers and investigates Internet threats, said on Thursday that its Threat Seeker Network has received reports of spoofed Facebook email messages that look similar to legitimate Facebook messages and invite recipients to click on the link contained in the message to view a video.

The subject of the mail could be "Amanda is dancing on Striptease Dance Party, March 10, 2009! We're absolutely shocked!", Dancing Girl Drunk In The Pub - face book Video, Magnificent Striptease Dance, Watch the Ooh! Super Beautiful Girl Dancing, Hot Girl Dancing At Striptease Dance Party, or anything like that, said a press release.

If recipients of this message click the link, they are taken to a malicious Web site that looks similar to Facebook and that prompts them to install a file called 'Adobe_Player11.ex', said a press release.

Websense said Websense Messaging and Websense Web Security customers were protected against this attack.

'Koobface' virus, that had hit the Internet in December 2008, recently made a come back. And the recurring incidents of viruses on networking sites have raised the concerns about security and privacy of those who have virtual existence on such sites.

Do you think the fraudsters are actually actually exploiting the users who look for some 'extra pleasure' online?
