:frowning: This Beta version has not solved the UI issue for me in Windows XP SP3…same problem, that AV service either failed to load or not responding.

I have uninstalled and reinstalled so many different ways now and yet nothing has worked re this problem which makes the computer impossible to scan.

I have for now migrated to another AV on my XP pc, with huge reluctance after 10 years of Avast use.
