What you really need to do is download 3 different registry cleaners with bonus adware, run them all at once, see how each gives you different results then buy them all in order to clean your registry. Then do the same with an AV. Once you have every adware known to man proceed to format your HDD and invest in a clean install.
The only things that have high memory are firefox, avast (20k) and games. That is pretty much it. And Sapphire Trix is about 10k. I am just trying to restore it to when I just got it, i.e. still keep windows 7.
