Hi Rick. I left it on all night and it stayed hung. So as Shane suggested I rebooted. Avast is working ok so will continue to use it for now.
Yes I have restore points. My computer is just a couple months old Windows 8. Only problem is with Windows Defender.
Is there anything in the event log to indicate anything we can understand?
is Windefender running in services automatically set to delayed?
when you run msconfig, is Windender running?
shane might write a program to enable WinDefendr if he has not already to enable windenfender
Denfender might It might be that Avast is not compatible to run with Win 8 yet
