Thanks for your reply.
While I was waiting for an answer to my post, I decided to run Malwarebytes. This only found some PUPs associated with Auslogics Disk Defrag. I will add the results at the end of this message.
I ran the Avast boot scan as suggested, but the only thing that found was a corrupted file in the Downloads folder: File C:\Users\channeal\Downloads\childs.zip|>CHILDSGA Error 42125 {ZIP archive is corrupted.}
I have no idea what that file was for or where it came from, but I have deleted it now.
I also ran the Malwarebytes AntiRootKit scan but that didn't find anything at all.
The message about Windows Update still keeps on appearing though!
Chris.
