Further to the above, and after reading many complaints from people whose
concerns and refunds do not appear to have been addressed;

Two days ago I advised Avast Support of my problems and raised a ticket
requesting cancellation of my subscription for SLVPN and a refund.

This morning I had an email from Avast saying my request had been
actioned and a second email, from PayPal, saying the refund had been
received and credited to my account.

Going through the correct channels worked for me.

Top service!

I am still using and will continue to use my old faithful Avast AV and Cleanup.
