Kama Sutra Worm Could Make For A Bad Friday 317
mikey1134 writes "CNN is running a story about the Kama Sutra worm, a virus that is coded to overwrite files of the (potentially thousands of) infected computers. They provide some background on this viral outbreak and warn users to protect themselves" From the article: "And even for home computer users who have never taken such precautions before, security experts say now would be a good time to back up your most important data, like financial information and family photographs, to CDs, DVDs, zip drives, or an external hard drive that you know is worm and virus free. Unlike a lot of malware that exploits vulnerabilities in the Windows operating system, there is no 'patch' that can be downloaded to ward off Kama Sutra."

And, if it's worth anything to you, the Microsoft advisory [microsoft.com] which seems to tout that Windows Live Safety Center Beta [live.com] can protect against it. If you're in charge of computer security at your workplace, I would send out an e-mail instructing everyone to verify that they have the correct anti-virus definitions and to scan their computers before leaving tonight. Luckily, that's not my job where I work.

Yes, the Worm tries to delete anti-virus program files. Yes, tries to stop anti-virus software running at reboot. But if it's managed to do that, there's no way you're scanning your PC tonight anyway.
Update your definitions and scan now. Inform everyone you know not to open email attachments they weren't expecting.
Which brings me to another point: Do people really get hit with these anymore? It won't make it though all the major webmail services. You haven't been able to open *.PIF or *.SCR files in Outlook for years now. You almost have to go out of your way to get infected by email worms these days.

Windows OneCare, which is NOT a remote control system by the way, does find it because, well, it's a virus scanner just like any other. It catches it just like AVG, F-Secure, Norton, and so on, which is to be expected as it's a competitor.
