Threat Description



Aliases:Deadbabe, SC.Replicator


This virus was found in the wild in Denmark in February 1997.

It stays resident in memory and infects all EXE files that are executed. The virus does not activate in any way.

The virus contains this text string:


The virus is named after it's "are-you-there" call: it calls INT 6Bh with hex value BABE and expects to find the return value DEAD.

Deadbabe will reinfect infected files. As a result your files can have dozens of infections and they will be several kilobytes larger.

F-Secure anti-virus products will disinfect Deadbabe fine, but because of a bug in the virus, the disinfected files will sometimes be longer than the original. This extra area might also contain pieces of the virus, which could cause false alarms. If you encounter problems like this, delete the files and reinstall or restore them.


Automatic action

Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.


You may wish to refer to the Support Community for further assistance. You also may also refer to General Removal Instructions for a general guide on alternative disinfection actions.
