SillyFDC is a worm affecting all versions of the Microsoft Windows operating system. The worm has several different variants.

The worm spreads by copying itself to removable drives on infected computers. It will copy itself as the file “svchost.exe” as well as creating various registry entries. The registry entries will alter the behavior of Internet Explorer. 

This worm can contact a remote location and potentially upload or download information to or from the infected computer.

Worms often run silently in the background and can be very hard to detect. Always run a regular scan on your PC.
