Windows 7: Tweaking AVG Resident Shield by excluding files?

Has anyone bothered to tweak the AVG Resident Shield by manually excluding files or directories that you know are "safe" and don't need to be scanned every time they are launched or accessed? Seems like this could improve performance and system responsiveness. For example, does AVG really need to worry about games that I've played a hundred times without incident? Or other application executables that are unlikely to be the source of an infection?



Of course the time it took me to type this is probably longer than the entire scanning time it would save over the life of the PC, but that's not the point...

That is a judgement call. I have excluded one program from my MSE because MSE kept it from loading normally (took 3 minutes in lieu of a second to load it). But just for the fun of it, I would not exclude anything. As you said, at the end of the day it buys you nothing - especially if the scans run in the background.
