I've used Malewarebytes and Spyware Blaster for many years, running them about every other day along with deep scans from Norton.
I don't know what happened, but when I went back to my computer this morning, booted up and signed on to AOL through Firefox, it worked. However, I've been busy resetting many things on AOL that apparently disappeared after doing the Safe Mode thing. At least I didn't lose my bookmarks. Thank you all for your replies.
