Rootkit activity

No anomalies have been detected.

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.

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):

    cscript.exe:1784

    %WinDir%\Installer\{19F1712F-0B24-636E-A837-9F7F5EGDDEFC}\setup.exe (6841 bytes)

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

    [HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce]
    "wextract_cleanup0" = "rundll32.exe %System%\advpack.dll,DelNodeRunDLL32 C:\DOCUME~1\"%CurrentUserName%"\LOCALS~1\Temp\IXP000.TMP\"

    [HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]

    "setup recommend" = "%WinDir%\Installer\{19F1712F-0B24-636E-A837-9F7F5EGDDEFC}\setup.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.
