mutt DVD Lab Pro installed it
JC_N optical drives disappear when pfc.sys is disabled
Scree Installed by InterVideo products that include cd burning capability, such as WinDVR, WinDVD, etc. May cause incompatibility with other burning software or dvd/cd drives. If don't mind disabling cd burning in such apps, can remove by deleting pfc.sys, deleting the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pfc, and removing pfc from LowerFilters at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\[the key for "DVD/CD-ROM drives"].
Tony I think it is a file which will be created while a software in relation to the use of CD/DVD. So it's not dangerous and better not to delete it .

WOFall I'm pretty sure it's installed by "Sonic MyDVD". I did not try to remove it. It is not possible to verify its signiture. May be related to Roxio (who own sonic)  See also: Link
ultramage seems that clonecd also installs this; errors out on Vista
Alex I removed it and lost my DVD (XP 64)  See also: Link
Philippe if you have tried WinDVD and then uninstall it, your burner will no longer recognize unformated CDRWor DVDRW, Had to delete it, remove the keys, go to thedevicemanager, select the burner, delete it so that its driver gets disabled and uninstalled, then reboot to have the DVD recognized again without PFC.SYS in the list of files for the DVD driver. Anyway, It's not signed. Causes just havoc with other burning softwares. Nor dangerous by itself but works only with some specific burning softwares that need it (I wonder why WinDVD requires it for reading a DVD, but it breaks burning)
Growler Seemed to be installed with Nvidia Purevideo Decoder
Wm Rickert Causes Crysis to crash in Vista Ultimate x64 Delete it. Vista doesn't need it anyway.
