Technical Details

This Trojan has a malicious payload. It is a Windows PE EXE file. The size of infected files may vary from 28KB to 255000KB. However, all variants of this Trojan have the same malicous payload. The majority of the Trojan file is garbage code in order to mask the Trojan functionality.


Once launched, the Trojan extracts a BMP file from itself and will display it on the victim machine.

The images show may vary according to the Trojan variant.

The Trojan replaces user files with the BMP file contained in its body.

As a result, the operating system will become non-functional.

Removal instructions

If your computer does not have an up-to-date antivirus, or does not have an antivirus solution at all, follow the instructions below to delete the malicious program:

  1. Use Task Manager to terminate the Trojan process.
  2. Delete the original Trojan file (the location will depend on how the program originally penetrated the victim machine).
  3. Update your antivirus databases and perform a full scan of the computer (download a trial version of Kaspersky Anti-Virus).

This type of behaviour covers malicious programs that delete, block, modify, or copy data, disrupt computer or network performance, but which cannot be classified under any of the behaviours identified above.

This classification also covers “multipurpose” Trojan programs, i.e. those that are capable of conducting several actions at once and which demonstrate several Trojan behaviours in a single program. This means they cannot be indisputably classified as having any single behaviour.
