Thanks for your response. I don’t know how it happened but after following your first suggestion it now seems to update and run a scan. I opened Spybot in Administrator mode, Advanced User was already selected, I went to Update and clicked on Show Update Log. The Update.log file opened so I tried running a scan. At first it wouldn’t run but on the second attempt it did. I thought maybe it was Administrator mode that made the difference so I opened Spybot in the normal way and it again updated and ran a scan.
I’ve also kept your link to manual updating info.
I’m a bit mystified but you seem to have solved the problem so thanks again!
