According to this News.com article, Kama Sutra isn't just for sex anymore: "Kama Sutra worm set to bite next week."
This tricky little e-mail worm spreads under the guise of pornographic content. It uses a variety of subject lines, such as "School girl fantasies gone bad." The text includes references to the Kama Sutra, the ancient Sanskrit book with pictures and explanations about different sexual positions. When the user opens the attachment, the worm executes and gets ya!
"The virus, dubbed Nyxem.E among other names, was first reported on Jan. 16. It is thought to have infected more than half a million PCs. Security vendor IronPort warned Thursday that these machines are now hard-coded to propagate the virus on Feb. 3." Fortunately, companies that have up-to-date antivirus software will most likely not be directly affected.
Word of advice... if you are interested in learning about Kama Sutra, search the Internet, visit your local library, or stop by a book store. Resist the temptation to open provocative e-mails, or you may end up getting more than you bargained for!
