KMC,

Try this: Disable the Archive scanning of Avast, and make sure the Scan sensitivity is at “mid range” for now.

Some system files are automatically “protected” and you will not be able to access them directly. As Eddy stated, some Spybot and Adaware files come up as “unable to scan”. Not to worry.

See if the total number of files decreases significantly with the above instruction. If not, then try a simple “repair”. Use Control Panel/Add-Remove/
Avast…find and click on the option to repair.

Then try again.

Let me know.

Happy Holiday. :wink:
