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 Worm'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):
   

   Service2.exe:1604
   Service2.exe:552
   wuauclt.exe:344
   reg.exe:1696
   reg.exe:340
   reg.exe:1184
   reg.exe:2020
   

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

   %Documents and Settings%\%current user%\Local Settings\Temporary Internet Files\Content.IE5\9U95XQO4\desktop.ini (67 bytes)

   %Documents and Settings%\%current user%\Application Data\FacbookUpdate.exe (10815 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\Stealer.exe (3806 bytes)
   

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

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

5. Clean the Temporary Internet Files folder, which may contain infected files (How to clean Temporary Internet Files folder).
   
6. Find and delete all copies of the worm's file together with "autorun.inf" scripts on removable drives.
   
7. Reboot the computer.
   

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