AVG is an absolute bear for system resources. Back at the end of last 
year when I got Portal, I couldn't run it at all. I would get to some 
complex location in the map, and would land on the desktop with a system 
message about not being able to get a texture lock. Quick search of the 
net, most of the people complaining were using AVG. Turns out, AVG had a 
tendency to acquire lots of mutex objects in the OS part of ram, so many 
infact that a moderately well programmed game would have to fault 
because it couldn't get a lock.

Several patches from both sides have fixed the issue, but I wouldn't be 
surprised if it still slowed things down as the OS paged those mutex in 
and out of virtual ram.
