Updated to 5.0.584 without any issues.
Thanks to all the members of the Alwil team who work so hard in helping to keep our PCs safe from infections.
I noticed that 'AvastSvc.exe' file is much larger in this latest version. Last version was 27,204K. .594 version is almost 50meg (49,876K). That's a pretty big jump in size.<<< edit >>>
I now see that the memory usage actually goes
DOWN after awhile. After my PC has been running for awhile, 'AvastSvc.exe' is only using 25,554 ... with a peak use of 40,792. So actually ends up using LESS!
