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):
   

   msconfig.exe:356
   msconfig.exe:1400
   %original file name%.exe:1108
   

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

   %Documents and Settings%\%current user%\Application DataMicrosoft\System\Services\18.exe (601 bytes)
   %WinDir%\Microsoft.NET\Framework\v2.0.50727\CONFIG\security.config.cch.new (804 bytes)

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

   [HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
   "18.exe" = "%Documents and Settings%\%current user%\Application DataMicrosoft\System\Services\18.exe"
   
   [HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
