Batzback.B

Posted: May 22, 2009

Batzback.B (dubbed W32/Batzback-B by Sophos) is an annoying and ultimately useless worm. Batzback.B’s goal? Batzback.B just disables some of your computer’s software, including system tools such as Folder Options, Task Manager, and Registry Editor. Batzback.B also spreads via network and local drives, dropping a copy of itself on every drive it can access.
