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.

Removals

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):No processes have been created.
  2. Delete the original Trojan file.
  3. Delete or disinfect the following files created/modified by the Trojan:

    %WinDir%\system.ini (72 bytes)
    %Program Files%\Common Files\Adobe\ARM\1.0\AdobeARM.exe (4 bytes)
    %Program Files%\Adobe\Reader 9.0\Reader\Reader_sl.exe (1336 bytes)
    C:\totalcmd\TOTALCMD.EXE (858 bytes)
    %Documents and Settings%\%current user%\Local Settings\Temp\winvdwve.exe (561 bytes)
    C:\autorun.inf (294 bytes)
    %Program Files%\Common Files\Java\Java Update\jusched.exe (272 bytes)
    %Documents and Settings%\%current user%\Local Settings\Temp\dtqe.exe (561 bytes)
    C:\psypgk.pif (99 bytes)

  4. Find and delete all copies of the worm's file together with "autorun.inf" scripts on removable drives.
  5. Reboot the computer.
*Manual removal may cause unexpected system behaviour and should be performed at your own risk.
