The Blackworm/Kama Sutra worm drops its deadly payload February 3.
Microsoft will release its Malicious Software Removal tool on February 14:
…As described in the write-up, the worm will corrupt common document format files, first on February 3rd 2006 and on the third day of every month moving forward. As always, we strongly recommend running an up-to-date antivirus program on your computers and being wary of opening suspicious e-mail attachments even if they were sent from a familiar mail address.
…Microsoft releases a new version of the Windows Malicious Software Removal Tool every month on the second Tuesday of the month together with the other security updates. The next version, targeted for release on February 14th will detect and remove this worm.
Also, the beta version of Windows OneCare Live protects against this threat. It can be obtained here: http://www.windowsonecare.com.
