Sounds like a general problem. Is your mouse driver up to date..!?

A General problem would occur all of the time (at least to my way of thinking), not just when the AvastUI is open and it isn't happening all of the time.

I'd still like to know what mouse, brand, model, etc. Any special software used for the mouse.

Once again thank you for the follow ups.

Yes, I agree with bob3160 - it could well be any software that works with the mouse -
some background -

The first mouse was the standard HP USB wired that came with the desktop.
I must have been having problems with it - because I ordered a cheapo USB wired optical mouse from eBay at the end of Jan/2018 to replace it.
(I started using Avast Free Dec/16/2017)

Please note as posted earlier "Windows device manager check for updated software says the mouse driver is up to date"

By mid April/2018 probably had double left-click (when single clicking) problems and installed CickFix -
https://www.clickfix.cf/
and
https://github.com/CemraJC/clickfix

Then I found the clicking problem was probably due to the cheapo mouse becoming slightly opened probably due to banging -
once I had pressed everything back together - things seemed to work fine - but I kept CickFix in place but reducing the delay time to only 21ms
chose that time from the pdf "A Guide to Debouncing" by Jack G. Ganssle
https://pubweb.eng.utah.edu/~cs5780/debouncing.pdf

So granted it may be the ClickFix software (and/or the cheapo mouse) the  that's causing some incompatibility/interference with Avast Free
(and perhaps Kaspersky Free registration window)

But for now I am not going change anything while things seem to work,
as uninstalling and installing antivirus is not trivial.

Thank you all for your help

Kaspersky anything and Avast are not good combinations.  :(

Sorry for not being clear -
After I had uninstalled Avast Free and ran Avast Clear -
then attempted to on line install of Kaspersky Free -
at end of installation, opened their registration window -
there mouse left-click was similarly disabled. 

By exiting with Alt-F4 - restored mouse function.

[note: just to be clear I have never tried to install more than one antivirus at a time- have always cleanly uninstalled any, before trying to install a new one]

Thanks
