This question was answered on January 30, 2006. Much of the information contained herein may have changed since posting.

PC users are being urged to update their anti-virus software before February 3rd in an effort to protect against the mass mailing worm known as W32.blamal (or the Kama Sutra worm), which is written to attack machines on the 3rd day of every month

Once a machine is infected, the payload will destroy all files with the following extensions:

*.doc (Microsoft Word)

*.xls (Microsoft Excel)

*.mdb (Microsoft Access)

*.mde (Microsoft Access)

*.ppt (Microsoft PowerPoint)

*.pps (Microsoft PowerPoint)

*.zip (Compressed files)

*.rar (Compressed files)

*.pdf (Adobe Portable Document Files)

*.psd (Adobe PhotoShop)

*.dmp (Windows Memory Dump files)

Note: The destroyed files have the following text:

DATA Error [47 0F 94 93 F4 F5]

The most likely way to get infected by this worm is to open an e-mail or instant messaging attachment that is infected with this self replicating worm.

If you open the file attachments that accompany these messages, your security software is instantly comprimised and can no longer protect you!

Most anti-virus programs have had a virus definition for this threat since January 17th, so keep your security and anti-virus software up-to-date and run a full system scan before February 3rd just to play it safe.
