Sounds like you’ve got a cookie (or something) from a disreputable malware/av company embedded on your system/HD, doing that crap. I periodically use Windows Explorer to search for “cookies” and delete them all. I got it once from WU, too, years ago, but Norton 360 & Malwarebytes zap all that pesky garbage now.
Thanks. I reset my internet options, supposed to clear them now. (except FR).
