Malware Bytes has a basic free download. I just downloaded it this week. I had 11,000 malware (ad hickies) on my computer. Cleaned them all up....took a long time, and you can't be using your computer while it is running, but it is amazing how fast my system is and no pop ups. BTW, to you have pop ups blocked on your computer?
Go to Tools, there is a tab for Pop Up blocker, turn it on. Perhaps that will help.
