More Information
W32/SillyFDC-M is a worm for the Windows platform.
W32/SillyFDC-M also creates the following files on the infected computer;
<Windows>\cmd.com
<Windows>\svchost.com
<System>\driver.exe
<Windows>\wuaucll.exe
W32/SillyFDC-M attempts to periodically copy itself to removeable drives, including floppy drives and USB keys. The worm will attempt to create a hidden file Autorun.inf on the removeable drive and copy itself to the same location as the filename music.exe
The file Autorun.inf is designed to start the worm once the removeable drive is connected to a uninfected computer.
The following registry entry is changed to run wuaucll.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

The following registry entry is set or modified, so that wuaucll.exe is run when files with extensions of EXE are opened/launched:
