Check the cooler for dust. Usually when the CPU heats up, it will throttle itself to prevent overheating.
Cpu cooler is clean, that was first thing I checked
Also the cpu temp is normal at all times even during the slowdown.
Regarding the antivirus stuff, i removed everything for testing purposes, I cut off the internet connection.
And even so I am not really worried about infections I am sure I dont have any. I work for a security software company, I checked my machine with all our scanning tools and its fine.
Any other ideas?
