Most of you probably know from news reports that as many as eleven new worms have been infecting computers worldwide since Sunday August 14, 2005. The outbreak started when a worm named Zotob spread rapidly on Sunday. New and much more malicious worms have been spreading to Windows 2000 workstations and servers, Windows XP workstations, and Windows 2003 servers since.
Microsoft has posted a malicious software removal tool that is able to find and remove all known variants of those new worms in addition to Blaster, Sasser, and Mydoom that have been around for a while. Microsoft's tool can be run from the web at
http://www.microsoft.com/security/malwareremove/default.mspx.
Everyone should run that tool, because even though some of the worms cause computers to continually reboot or exhibit other problems; computers infected with other worms continue to run normally while sending spam, engaging in denial-of-service attacks, and other things transparently in the background.
