I scheduled a boot-time scan with my avast and when I tried restarting the computer, Windows went into the Startup Repair and was unable to resolve the issue. It seems like Vista is detecting the boot-time scan as an issue and is not letting the OS boot up until it resolves it. I've tried everything I could think of, including booting in safe mode, but whatever I choose to do, it always ends up going to the Startup Repair and failing to fix it. I thought that if I could uninstall avast from the command script, then maybe that would work, but I don't know the code to do that. Can anyone help me out?
