I was having the same problem with Vista, I took vista off my laptop and installed windows 7 ultimate and did a clean install I then installed the free version of avast. 2 days later, when starting up my laptop, the same problem occured, i could sign on to windows, but at that point the screen goes black with only the mouse curser, which I can move around but nothing more. I was able to get a window up with hitting the shift key a few times and pulled up the control pannel, and was able to do a restore before avast and it booted up perfect. So, what now? I love avast but for some reason the new version is giving me problems. Any ideas? Any suggestions on virus protection programs
thank you
