W32.Gubed.int

W32.Gubed.int is an intended mass-mailing worm that attempts to send itself to all email addresses that it finds on an infected computer. The subject of the email message is "Congratulations for your site," and the attachment is "WebMakeFullInstall.exe." The worm also drops a script that is an intended mass-mailing worm, but due to bugs in the code, the script does not perform the mass-mailing functionality.

The worm copies itself as \%System%\DebugW32.exe, copies itself five times to both the \Windows and \Windows\System folder, and creates the Start.vbs file in the Startup folder. Start.vbs attempts to overwrite .vbs files that are in the My Documents folder and its subfolders.
