W32/SillyFDC-W is a worm for the Windows platform that spreads via removeable shared drives.
When run W32/SillyFDC-W copies itself to
<System>\Lcass.exe
W32/SillyFDC-W spreads via removeable shared drives by creating the file autorun.inf and a copy of the worm to <Recycler>\Lcass.exe on the removeable drive. The file autorun.inf is subsequently set to run the worm component upon connecting the removeable drive to another computer.
W32/SillyFDC-W creates the following registry entry:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Lcass
<System>\Lcass.exe
