Intrusive malware-like popups

Recently, upon accessing a site via a non HTTPS connection, I have had an intrusive malware-like pop up appear, 2 or 3 times now, saying that our TV equipment is oudated and needs to be upgraded, which is a crock, since it works fine. Cease these invasive pop ups immediately or we will be switching to Verizon. Especially if you reply with some automated BS and lock the topic.
