Koobface is a worm affecting all versions of the Microsoft Windows operating system. 

This worm is currently spreading through social networking sites and if you are infected the worm copies itself to your computer as “ld12.exe”. This presence of this file will indicate that you may be infected.

The worm will also add various registry keys and delete certain keys from the Windows Registry.

This worm can then notify various external sites as well as download data from external sites. There is the possibility that further harmful malware could be downloaded to your computer.

Always scan for worms and trojans on a regular basis as many of them operate silently in the background.
