• use a compressed image type like PNG or JPG to save the screenshot

I couldn't enter a screen shot, but each one of the pop-ups had an email address: www.wefindanswers.co. I went to this site and I believe I turned off the notifications, but I will have to see if it worked. Anyway, thanks for being willing to get involved with this issue. David Barton

You can do a malware scan just to be sure.
