I'd forgotten about Windows Defender so I checked it this morning. It's set to run daily at 2 am daily and it was clean. I've changed that to do a full scan to see what it shows.
I'm also suspicious of Comcast at the moment. Not that long ago, I think they made a change to the spam folder. It used to be that you had to click on a spam email to view it. Now when I go to that folder, it opens the first email to view it. I never opened them, I checke marked then and then hit delete.
Generally I view most emails thru Outlook.
I'll see what WD comes up with. If it finds nothing, I'll try the mentioned software. At least I can use IE on the desktop with no problems.
