I downloaded TweakVista 2 days ago and all my computer does is freeze up when I try to use it. I have been trying to deinstall the product using Programs and Features in the Control Panel, but nothing happens, even if I walk away and come back to my desktop an hour later. I am sure this program works very well for others. I got the link through Norton PC Booster and it was highly recommended. Is there a deinstall tool similar to Norton's to remove this? My system has slowed down considerably since I installed. I have also tried to go back to a restore point, but it gives me an error saying that my system cannot be restored and that no changes were made. HELP!
