Anway...
3 days ago I woke up and went to my PC and noticed that my RAM usage was maxed out completely (via the Task Manager as well as my sidebar gadget) and my system was ridiculously slow so I had to reboot. I decided to not go crazy uninstalling anything yet and see if it happened again the next morning.
Sure enough it did, and I realized the last thing I installed was the new Anti-Vir. When I installed it, I had set it to do a full system scan at 4am every day so the first thing I did was disable that scan and wait for the next morning to see if that fixed the issue.
It did not... So, I uninstalled it completely and magically I no longer have to reboot every morning for my PC to become usable again.
Currently I went back to the latest v8 build and don't experience any of those issues.
What could be causing this and how do I go about diagnosing it?
