Instead of removing Avast i simple repaired it in before the uninstall and rebooted.
I think everything is a little faster now too.
I'm my search for a fix I cam across this in MoBo.org
"If you use more than one antivirus or antispyware program at the same time, your computer may experience decreased performance, become unstable, or restart unexpectedly. Before you install Microsoft Security Essentials, or to resolve many issues with Security Essentials, including installation issues, you must first completely remove any Internet security programs from your computer as described in this topic."
How do I uninstall antivirus or antispyware programs? | Microsoft Security Essentials
The good news is all is better now.
