Thanks for your timely reply. I had previously tried a mulitude of things including stopping and restarting system restore with no change to the problem. I can manually take a system restore point without issue. I had the VRDB disabled, and have now changed it to start when the screensaver comes on, I’m curious to see if that changes anything. If not, I will uninstall and reinstall Avast, perhaps there is something corrupted from the first install. I will keep you posted on my progress. Thanks.
