About BlackWorm
Over the last week, "Blackworm" infected more then 700,000 systems as measured using a counter web site used by the worm to track itself. This worm is different and more serious then 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.

The following file types will be overwritten by the virus: DOC, XLS, MDE, MDB, PPT, PPS, RAR, PDF, PSD, DMP, ZIP. The files are overwritten with an error message( 'DATA Error [47 0F 94 93 F4 K5]').

We will try to post more detailed cleanup instructions later. However, it is likely that you will have to rebuild the system from scratch. Obtaining good backups is critical as a first step.

The first thing you should do is to update your anti virus signatures.
