RPC server too busy

[Tweakforce_LG]

Ok the strangest thing just happened. I was watching a youtube video and it suddenly stopped working, so i reloaded it and even though it was bufferd it still had the loading sign. After that windows notified me that firewall was down and i tried to enable it but it said there was an error. So i killed the internet with the wifi button and immediately started a full avast scan. When i tried to it said "RPC server too busy". Then i unplugged my usb hard drive and killed the power to the laptop by the on button. I dont know what possibly happend, what could i do?

Im running on windows 7 pro 64bit with most of the latest updates.

Now im stuck with an old core 2 duo laptop

Bump! I ran avast rescue boot cd and it found 480 so infected files but the scan result said 0??? Witch is it avast? I clicked fix automatically and it froze. The virus cant have done that to a live cd?!? Anyway how come it said 480 infected files but then after said 0 infected files?
