Malware can easily corrupt the restore. Don't try to fix it using common tools. They already know about those and work around most. The first thing to do is disconnect from the internet and leave it disconnected until it is clean or rebuilt. Next use autoruns to shut off all the oddball startup programs (you'll have to use a usb stick). At that point you can try to update / repair using normal tools (e.g. restore from a backup)
I appreciate your input but I have no clue what you are talking about re: autoruns, usb stick. I’m an old lady who is not computer savvy by any stretch of the imagination. :)
