This morning Micro soft alerted me that it no longer recognized anti-spyware on my system. Avast also promted me to update. I updated with Avast. Avast asked to restart my system. I let it do its thing. Now I can no longer get back into Windows. It starts up and asked for my password. When I type my password it tells me that my computer is loading. It then restarts itself. It has done this fifty time today. I have attemped to restart in safe mode, and everyother mode offered. Was on Tech support with Microsoft for two hours today, they can't figure it out either. Any ideas. Keep in mind I can't access anything other than the initial F8 menu.
