It ran the fix that time.
I am currently stuck on a black screen with an unusable cursor. I had control of the cursor on the welcome screen to choose which user to login with. Then, after logging in I get the black screen. Cursor still worked for a few seconds then ceased to move.
I will reboot and post FIXLOG
I found this forum because it appeared that the last loaded file in my bootlog was aswrvrt.sys. Since, I have downloaded and used the avast uninstall utility.
