Disinfection & Removal

Automatic Disinfection

Allow F-Secure Anti-Virus to disinfect the relevant files.

For more general information on disinfection, please see Removal Instructions.

Technical Details

Upon infection, the size of the files will have been increased by 2048 bytes and the timestamp of the file will reflect the date the infection took place. The virus will add its own code in the end of the host's executable, creating for that purpose a section named XOR.

The virus contains the following string:

-= XOR 2009 Valhalla =- Assembled 1997 .. Activated 07.2002 - devoted for peace
 and harmony in universe against war, racism, terrorism and cruel brutality ..
 remember .. life is the most important thing - not money .. it's time for a
 revolution NOW ....

The virus does not have any means of spreading by itself through networks. In order for a computer to be infected an already infected file has to be manually run.
