I updated my Win7 pro desktop and after reboot, my login failed with the message 'The User Profile service failed the login. User profile cannot be loaded'. I rebooted again and same message. I had to run windows repair to be able to login again. Avast still says it needs an update to this new version. Is this a known issue? I'm hesitant to try it again or update my other machine and end up with a boat anchor I can't fix. Using Avast Internet Security. Thank you in advance for your help.
