I recently acquired a new machine from my mother who upgraded hers. I got home and got it all set up only to find out...

this machine has adware up the ass. I'm getting pop-ups for everything everytime my broswer loads a new page. I've ran yahoo anti-spy and hit remove all on everything it came up with and my pop-up blocker is on. I can't get rid of these damn things. Can anyone help me? My FTR viewing experience is in the shitter. Please...
