Bugbear

Virus name:   Bugbear (also known as Tanatos or Bugbear.B).

Status:   Real.

Origins:   Bugbear (and its June 2003 variant, Bugbear.B) is a mass-mailing worm that, once it infects a target system, can log keystrokes, enable a backdoor trojan, and stop antivirus and firewall programs. It replicates itself by sending out e-mail to addresses harvested from infected systems using subject lines such as the following:

The messages sent out by Bugbear can exploit vulnerabilities in some versions of Microsoft Internet Explorer and Microsoft Outlook that enable it to execute automatically when an infected e-mail is viewed. You can protect your PC from infection by Bugbear by downloading and installing the preventive patches offered by Microsoft for these security holes in Microsoft Security Bulletin MS01-027 and the Cumulative Patch for Internet Explorer Q323759.

If your system has already been infected by Bugbear, a removal tool can be obtained from Symantec or from F-Secure.

See the links below for more information on how to detect and remove Bugbear.
