I don't remember the rest but you may figure it out that happened after I downloaded some PDF and Quicktime 3GPP clips I don't know exactly the problem but mozilla was crashed and takes longer to close than usual and before it happen I think windows try to prompt me the program did not run correctly at first I don't think its a big matters but later when I click any programs it did not run at all and when I try to get to control panel whenever I try to do system restore it continue prompt as I mentioned above and the most funny thing is when in certain program like system configuration it blink with colors red, green, yellow, pink or such weird color like that on the program window and the most strange thing is I also lost my administrator word under my name on logon screen I already try system restore with boot (F8) until I can get here now on the internet but please help why did this happen?? by the way when I try to scan with avast the scanner takes too long when try to scan my :c\ drive is it because of virus or something else please HELP! my spec is under the end of this question page(
