Avast Free AntiVirus

I have a problem with the user interface. I try to open it & all I see is a blank, white screen. I’ve had Avast for several years & have never had that problem. I tried to repair the product via programs & features > Uninstall > Repair. What could be the problem?

did you reboot after repair?

No, never had to before. I’ll try that.

Hi, see: https://forum.avast.com/index.php?topic=225642.0

I went to programs and features > Avast > (right click) Uninstall > Update. I found out there was a new update (version 19.3). It installed & message showed I need to restart computer. I did & U.I. seems to work now. I have updates set to “automatic”. Some how when I started computer earlier this morning, Avast must have “hung”? I suppose I need to change update settings & manually check soon after starting computer every time? That is a time consuming pain…
Thanks for your prompt replies!

You’re welcome.
