Your problem is probably PC Health Boost—looks like it’s a scam. You might want to get rid of it. From this website: ““PC Health Boost” is a rogue program, which will show unsolicited ads and popups on the user’s computer to trick them into thinking that their computer has several issues, and into purchasing their paid application, which will supposedly fix all these “issues”.”
They recommend using Malwarebytes to get rid of it. I’ve used Malwarebytes and like it. It’s easy to use.
By the way, if you mean SuperAntiSpyware, you can turn off the pop-ups. Open the program, click the “PREFERENCES” button in the bottom left corner, then click the UPDATES tab on the top right. Uncheck the preference that says “Periodically check for application updates.” Then you can close the program. Sounds like PC Health Boost is the reason you’re getting pop-ups though.
