Act now to prevent data destruction from Blackworm

Windows users, please note that there’s some particularly nasty malware going around out there called Blackworm that you’ll want to protect yourself against — and you’ve only got a couple of days.

From the summary linked above:

Over the last week, “Blackworm” infected about 300,000 systems based on analysis of logs from the counter web site used by the worm to track itself. This worm is different and more serious than other worms for a number of reasons. In particular, it will overwrite a user’s files on February 3rd.

At this point, the worm will be detected by up to date anti virus signatures. In order to protect yourself from data loss on February 3rd, you should use current (Jan 23rd or later) anti virus signatures. Note, however, that the malware attempts to disable/remove any anti-virus software on the system (and does this every hour while the system is up), so if the machine was infected before [updated anti-virus] signatures were deployed, obviously, that anti-virus software can’t be expected to clean up the infection for you.
