I have been having sporadic freezes on my machine lately. There is no blue screen or crash screen. All the applications just stop responding and ~5~10 minutes later it will power off. After checking the event log a couple times, I have found that the same event occurs right before each crash.

File System Filter 'Avgmfx64' (6.1, ‎2011‎-‎12‎-‎23T08:08:12.000000000Z) has successfully loaded and registered with Filter Manager.

My question is twofold: I can not seem to find any information on what the Filter Manager actually is supposed to do. for curiosities sake, what is it? And more importantly, how do I fix this problem.

From the research I have done, I see that similar problems can be caused by out of date drivers, so I have already taken the time to update all of my drivers, run MemTest, and verify the drive integrity.

The Filter Manager was added to XP SP2 and up that acts as a sort of software shim and controller, but it is not your problem.

Your problem is with the anti-virus program AVG. Somehow it has gotten messed up. Your best bet is to uninstal it (including running the removal tool), and then reinstall it from scratch.

I had completely forgotten about this question. (In my defense, it is almost a year old.) The filter manager error ended up being a red herring. The real problem was that the default (one you got from Microsoft Update) version of .NET was not friendly with my machine. I read a forum post somewhere (which of course I cannot find) claiming that that particular version of .Net was not friendly with triple channel mother boards, (which I know sounds like a load of crap) so out of desperation I tried updating to a version off Microsoft's site, and what do you know, I never saw the problem again. – Alex N.

Yes, the question popped up because someone had posted a me-too answer yesterday, and the words Filter Manager caught my attention because it’s a sort of advanced thing. Well I guess the explanation of your problem makes some sense in a roundabout sort of way. It sounds like some system components were conflicting with your motherboard’s drivers, and by updating .NET (and/or your drivers), the conflict was resolved. That it affected the AVG drivers/services shows how interconnected and convoluted things can get and result in a jumble where error messages can be completely misleading. ¬_¬ – Synetech Jul 2 '13 at 16:02
    
Agreed. Although, most people with a similar problem are probably going to be more likely to need your answer than mine, so I'll mark yours correct. Enjoy the Rep. – Alex N. Jul 2 '13 at 18:13
