General false positive symptoms from untoward sources can help entice you to download real ones.

What you can do is download Malware Bytes from https://malwarebytes.com/mac.

What you have is basically adware / scare-ware trying to get you pay for additional worthless/harmful software and it needs to be removed.

The Malware Bytes program is a free trial that continues to work even after the trial is over and is a very legitimate product, unlike "Mac Cleanup Pro". Just install it, run it, and it should remove the adware that has tricked its way onto your system.

No, I don’t think this is valid. Unless your are really having issues. Ignore the message.
