Sophos computer security firm recently warned that hackers are spreading a nasty computer virus with a file promising a PowerPoint presentation of sexual positions from the Kama Sutra.

Clicking on the file does open a real PowerPoint presentation with more than half a dozen lovemaking techniques illustrated from the ancient Indian text. But in the background a Trojan called Troj/Bckdr-RFM gets installed which allows hackers to gain remote access to your system.

Once your computer is compromised, the hacker can steal your personal information and spy on user’s activities. The hacker could even use your machine for activities like sending spam or attacking websites.
