Description:
Win32.Cosmu.gen opens several connections to the internet. It downloads and installs several other malware on the system. It is able to replace all executable files on the drive, except the ones in the system32 directory. You have to add your drives to the list of download directories in order to find all infected files. The Trojan may also install an autorun entry "recovery" in order to start on reboot.
Removal Instructions:

Autorun:

Important: There are more autorun entries that cannot be safely described in simple words. Please use Spybot-S&D to remove them.

Files:

Please use Windows Explorer or another file manager of your choice to locate and delete these files.
  • The file at "<$SYSDIR>\Jibanu.exe".
  • The file at "<$SYSDIR>\xFile.com".
Make sure you set your file manager to display hidden and system files. If Win32.Cosmu.gen uses rootkit technologies, use our RootAlyzer or our Total Commander anti-rootkit plugins.
You will have to use a global search for files without a name specified. Be extra careful, because just the name might not be enough to identify files!

Important: There are more files that cannot be safely described in simple words. Please use Spybot-S&D to remove them.
