ok basically this computer isnt a pice of junk. i just got it a month ago. so today i installed an anti virus program, while i already had one one(was changing from one to the other) and all of a sudden my computer became super SLOW and wout even respond. the mose moves on the moniter but you cant open things it just shows the little hourglass. i tried the whole f8 thing but that didnt work and i cant boot into safe mode, or at least my comp doesnt have that option while starting up? anyone have any suggestions please?
