HOSTS file anomalies

No changes have been detected.

Rootkit activity

No anomalies have been detected.

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 HackTool'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):
   

   bridgemigplugin.exe:2928
   vbc.exe:2392
   vbc.exe:2056

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

   %Documents and Settings%\%current user%\Application Data\pid.txt (4 bytes)
   %System%\wbem\Logs\wbemprox.log (150 bytes)
   %Documents and Settings%\%current user%\Application Data\pidloc.txt (39 bytes)
   %Documents and Settings%\%current user%\Application Data\Winamp\bridgemigplugin.exe (5873 bytes)
   %Documents and Settings%\%current user%\Application Data\Winamp\FlashUtil__ActiveX.exe (15 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\holderwb.txt (2 bytes)

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

   [HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce]
   "Microsoft .NET Framework v1.0 compatibility" = "%Documents and Settings%\%current user%\Application Data\Winamp\FlashUtil__ActiveX.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.
