I had a month’s long minor system issue that has fortunately “gone away on its own”. I’m trying to figure out why.
Is there some place I can see the update log files and determine if there have been any program updates in the last few weeks that could potentially have been the fix?
There could be minor build numbering, dependant on what Avast Program (Free, Paid, additional features/components). You didn’t say what Avast Program you are using.
