W32.Sircam.Worm@mm

W32.Sircam.Worm@mm contains its own SMTP engine, and propagates in a manner similar to the W32.Magistr.Worm.
Due to what appears to be a bug, W32.Sircam.Worm@mm does not replicate under Windows NT, 2000, or XP.

Symantec Security Response has created a tool to remove this worm.

CAUTION: In some cases, if you have had NAV quarantine or delete infected files, you will not be able to run .exe files, however you will still be able to run the removal tool.





Configure Windows for maximum protection
Because this virus spreads by using shared folders on networked computers, to ensure that the virus does not reinfect the computer after it has been removed, Symantec suggests sharing with read-only access or using password protection. For instructions on how to do this, see your Windows documentation or the document How to configure shared Windows folders for maximum network protection.
