Virus writers have exploited interest in the anniversary of the September 11 terrorist attacks with their latest attempts to create a damaging email worm.

Fortunately due to bugs in the code of Chet-A it fails to work properly and is considered a minimal threat.

AV vendors reports few instances of the Windows-specific virus in the wild, those most likely arising from the VXers themselves mailing their malware to vendors, a common tactic about such s'kiddiots.

Even though it doesn't work, AV vendors have updated their tools to detect Chet-A. Users are also advised, as always, to treat unsolicited email attachments with deep scepticism. ®
