Yesterday, I finally updated to 4.7.844 from 4.7.763 reluctantly(it sneaked thru the Firewall and I answered yes to the Popup).
Due to other problems I had to do a System Restore on Windows XP SP2, which I thought would have removed this update. Then I did use another program - ERUNT which went further back in time than the aforementioned system restore.
The upshot is that I have seemingly both ,4.7.844 and 4.7.763 installed - see screenshot:
Also, the tooltip says - "avast! On-Access Scanner: 10 Providers(s) total, 1 running"
Hopefully, This can be corrected without having to do a uninstall /reinstall. I tried to do a repair,but no change.
