Please someone help, I am going out of my MIND with this. Okay, up until about 3 weeks ago, my computer used to work normally -now, it's being really slow and keep freezing so when I do Ctrl, Alt, Delete lots of things come up as "Not responding" and I have to restart. Something called mediadet seems to be causing a problem as I don't think it's meant to be in the computer system yet it's always running but I don't know if it's something else as well.
I have Spybot and Ad_Aware but they haven't solved it..
Someone please give me some advice..I am not technologically informed so explain it simply!
