I apparently downloaded a virus. Now no programs will work. Windows will boot up fine (although it takes a long time), but I cannot run any programs. Whether I click on a program icon or right click on it and choose "Open," nothing at all happens. I tried running fix_exe.reg and regfix.reg as recommended elsewhere in this forum, but nothing has changed. I tried doing a system restore to restore to factory defaults, and the computer reboots, but it is unchanged.
I was able to remove the virus using the Linux-based Trinity Rescue Kit, booted from a CD, but still can't get any programs to run.
Task Manager will open, and under "services," more than half of what is listed shows "stopped" under "status." If I right-click any of them and choose "start," I get the error message, "The operation could not be completed. Access is denied."
Any ideas what to try?
