Often on BSODs under Win 7 x64, but I doubt that this file causes the bluescreen...

I believe FLTMRG.EXE is Fault Manager. About 2-5 minutes before my BSOD I see AdAware fault. First once and 3 times in sucession. Always I get the BSOD implicating fltmgr.exe but I think it's really AdAware. I stop AdAware and haven't gotten the BSOD for weeks now.

It caused a BSOD on Windows 7 Prof. x64 probably because I yanked two USB drives without using Safely Remove first.

XP SP2 worked fine but the SP3 update would not load after updating the system. Booting in Diagnostics mode, the BSOD reported that FLTMGR.SYS was crashing the system.

Manages data for Windows. Viruses, malware, poorly written code, and pirated software cause issues with it. It is safe and important
