I've had this happen once before and a restart usually fixes it. I think it has to do with a profile error, but I'm not sure if is has anything to do with avast! so I'm asking anyway.
I am running Windows 7 64-bit, avast! Free, and MBAM Free. Thanks for the help.
If you need to know specs, it's an Intel i5, 1.5 TB hard drive, 8 gb of ram, and a HTI Radeon 6450 graphics card.
