Hello again,
Thanks for all the replies! Sorry, I didn't mean to imply Avast has had this problem for "years".
No, I cannot click on the tray icon as it is nowhere to be seen. I also tried looking in processes and applications in the Task Manager and there is no hint of anything Avast related.
Ditto for the Add/Remove programs list. The only way I know Avast is on my computer (somewhere) is I put it there, it appears in the DDS.txt log, and the ComboFix warning.
Here is the link to my Malwarebytes forum

I had last updated the program when everything crashed so I did a scan anyway. It only took 29 minutes as opposed to the normal 1 plus hours and found nothing."
In re-reading this I can certainly say I don't remember if it's still installed or not, but as I said earlier, the DDS.txt log and ComboFix indicate it is(?) Should I still go ahead and run ComboFix?
This all started the beginning of the year so please forgive my memory lapse.
Thank you all again for your help on this particular issue.
