Well AVG has gone, and so has all my issues.
Back to Comodo for all things but the AV.
Gone with Nod32 for AV.
All is running perfect now, with nothing going slow as far as i can tell.
AVG Free runs way better?
There was two processes that on idle took 100% processor. One was the real time scan, the other one was AVGCSVX or something similar, which i take to be the real time service? that took from 30-70% depending upon if the system was idle or not.
Causes issues with FlighSim FPS too, which has now gone with NOD32.
