Propagation

A worm can spread via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Trojan's file once a user opens a drive's folder in Windows Explorer.

Remove it with Ad-Aware

1. Click (here) to download and install Ad-Aware Free Antivirus.
2. Update the definition files.
3. Run a full scan of your computer.

Manual removal*

1. Terminate malicious process(es) (How to End a Process With the Task Manager):
   

   %original file name%.exe:1692
   keygen.exe:836
   keygen.exe:1452
   

2. Delete the original Trojan file.
   
3. Delete or disinfect the following files created/modified by the Trojan:
   

   %Documents and Settings%\%current user%\Local Settings\Temp\keygen.exe (50052 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\crude.exe (1577894 bytes)
   %Documents and Settings%\%current user%\Application Data\Microsoft\svchost.exe (2105 bytes)

4. Delete the following value(s) in the autorun key (How to Work with System Registry):
   

   [HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
   "svchost.exe" = "%Documents and Settings%\%current user%\Application Data\Microsoft\svchost.exe"

5. Find and delete all copies of the worm's file together with "autorun.inf" scripts on removable drives.
   
6. Reboot the computer.
   

*Manual removal may cause unexpected system behaviour and should be performed at your own risk.
