I think you’ve got it, I don’t have the relevant patches although I run Windows Update regularly. Microsoft must have removed it from the list of Critical Updates because that particular patch never showed up. Darn them. Just run Windows Update again and those updates still didn’t show up.

I wasn’t able to get the scanner tool to work - I don’t know enough about DOS and I don’t understand how the different commands Microsoft list work - but I looked in Control Panel and those particular patches are not listed. Should I install them first, then turn off System Restore and run Avast and tell it to delete forcibly on restart? or try running Avast again and then install the patches?

Sorry to be a nuisance but I’ve never had this particular situation before, I’ve always had all patches in place. I don’t know why those patches haven’t come up in Windows Update which I run regularly.

Thank you so much for helping me with this and for taking the time to look for me. I did look on the Symantec web site and this particular virus didn’t seem to be listed, wish they’d install a search facility!
