I was having shut down/turn on problems & was told antivirus conflict. I uninstalled AVG 8 & Spybot. Now I can download AVG, but when installing, it kicks me out and does the off/on again. I am running: XP SP 3 Home Ed. AMD processor 1.68GHZ 2.0 GB RAM Initially AVG would not complete a scan saying corrupt. I have cleaned the disk & defragged. I am in safe mode on the other computer at the moment. I have uninstalled AVG & Spybot using add/remove and going to program files and deleting. In safe mode, AVG will not let me delete what is left there??? I did Spybot. I tried a third free antivirus and it will kick me out during installation and off/on all over again? I download CCleaner & I am nervous about that program. Not familiar with it. I have restored to previous time and that did not work. Uninstalled most frequent program downloads. Can't get on line in safe mode to get on line assistance. Any help appreciated. Much thanks.
