Summary:

Trojan-Dropper. Trojan program, intended for stealth installation of other malware into user's system.
VirTool. A program used to apply passive protection methods to viruses, such as obfuscation, encryption, polymorphism. The original virus is usually encrypted/compressed and stored inside the wrapper.

Propagation

A worm spreads 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):
   

   eb27c6a1e22f6b539f214fdfd521c33b.exe:1324
   wuauclt.exe:344
   

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

   %System%\svchost\svchost.exe (5441 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\XX--XX--XX.txt (3820 bytes)
   %WinDir%\SoftwareDistribution\DataStore\Logs\edb.chk (100 bytes)
   %WinDir%\SoftwareDistribution\DataStore\Logs\edb.log (3576 bytes)
   %WinDir%\SoftwareDistribution\DataStore\DataStore.edb (100 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\XxX.xXx (14720 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\UuU.uUu (104 bytes)

   %Documents and Settings%\%current user%\Local Settings\Temp\X-Timeroulette.exe (1794 bytes)
   %Documents and Settings%\%current user%\Local Settings\Temp\jusched.log (347 bytes)

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

   [HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
   "cftmon" = "%System%\svchost\svchost.exe"
   
   [HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
   "HKLM" = "%System%\svchost\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.
