Avast Internet Security user interface failure

Avast Free Antivirus / Premium Security
1

Avast Internet Security on my Dell Inspiron 6400 using Windows Vista started to fail yesterday. The user interface does not start. I keep restarting the program and my computer, and nothing works. I had to subscribe to a 60-day free trial to Avast Internet Security. That will be a waste of money if the program does not resolve and the trail period renews automatically.

Update to the latest version (18.6.2349): https://forum.avast.com/index.php?topic=221320.0

I cannot update if I keep receiving “UI is down” messages. Please advise.

Should both “Terminal Services” and “Terminal Services Configuration” be set to Automatic?

I am working with “Terminal Services” and not “Terminal Services Configuration” at the present.

I was on 18.6.2349 (build 18.6.3983.0).

I clicked “Update” under Program. Now I have a “not responding” message.

My affected computer must be using a lot of memory trying to update Avast Internet Security. I have power it down, will restart it, and, hopefully, it will have energy to do something.
