What started all this was a failure of the microsoft security essentials to protect my computer.
Are you still running MSE along with Avast? The reason I ask is because you cannot run 2 resident AV's on your machine at the same time as this will create conflict and chaos on your machine. If you intend to keep Avast, which is sounds like you do, you will need to uninstall MSE
http://support.microsoft.com/kb/2435760/, then reboot.
I then suggest an Avast Repair since you had 2 AV's:
- Go to Control Panel > Add/Remove programs > Avast Antivirus.
- Scroll down and choose Repair function in the pop-up window.
- Reboot.
If this fails to fix Avast, you will need to uninstall and do a clean install of Avast:
1. Save a copy of newest version of Avast (5.0.677) for the product you need and save it to your HDD:
Pro –
http://www.avast.com/pro-antivirus#tab4AIS –
http://files.avast.com/iavs5x/setup_ais.exe2. Download the Avast Uninstall Utility, aswClear5.exe
http://www.avast.com/uninstall-utility and save it to your HDD.
3. Disconnect from the Internet at this time.
4. Go to Control Panel and uninstall Avast through Add/Remove Programs if possible and reboot.
5. If Step 4 fails, boot into
Safe Mode (hit F8 repeatedly) and run the Avast Uninstall Tool. Uninstall the product(s) of Avast you have on your machine at this time.
6.
Reboot.
7. Install the newest version of Avast and
reboot.
8. Get Internet access and register your copy or add the license key for Free, Pro, or AIS.
9. Update the Avast definitions.
