For 2 weeks I have been trying to determine what is causing the problems I am having with Windows 7 but with no luck and a few other people telling me they are experiencing the same problems. I have ran antivirus scans with AVG 9.0 with no luck I have also ran Malwarebytes and SUPERantiSpyware also with no luck. The symptoms are as followed: Can not open and run any antivirus program in normal mode only in safe mode. Can not run windows update. Windows update also says I have never updated which I have. Can not run any internet program except Internet Explorer. Internet explorer runs the goes to not responding.When shut down can not reopen explorer have to restart PC. All system restore points were deleted. Made a new point and that was deleted. Can not open task manager any way. (alt ctrl del or right clicking on right side of task bar.) I also can not add/remove programs. Computer is a Toshiba Satelite with AMD Turion X2 processor Vista was installed and was upgraded to Windows 7 Ultimate. Another person I have talked to with same problems on 2 computers had to do a fresh install of which I am trying to work around doing. I have files on this computer I dont want to lose. I have time to play with the machine before I have to reinstall. So any help would be great.
