@Sharky7Sharky: Repair operation failed - actually gave me a BSOD.

@Tech: Avast! uninstalled from Control Panel, but (in safe mode) I also ran the uninstaller. Despite that, directories still remained from the Avast! installation. I manually had to remove them.

The computer I am on is a bit problematic as it will occasionally simply freeze in place. I have to power down to recover. I’ve been troubleshooting it for the last three weeks and have found nothing as of yet. In order to eliminate Avast! as the source of trouble, I installed MSE on just this computer. As result of this, the computer boots up in a record 30 seconds from cold-start to desktop. Previously (with Avast! installed) it could take up to four to six minutes before I was able to begin operations.
