Issue Solved!---Avast back in on Desktop and Laptop, and all seems to be well
before I had my Temporary internet file folder disappearing in Windows 10 Internet options, deep down I knew wasn't Avast causing it, if was would be a big news story in the tech web, so against my local PC techs advice I decided to do a repair install of Windows 10 Pro x64 on the Desktop and so far seems to have completely solved the issue was having with the Temporary Internet file folder going missing and Edge stopping to work
Local PC tech kept saying you don't need Avast, you got Defender that offers same or better protection
Anyways happy to stick with Avast here!!
