How to stop McAfee pop ups?

Literally one pops up EVERY 2 seconds (I've counted), and it says "Potentially Unwanted Program Blocked", It gives to options "Remove" (Which I've already done 10 times) and Close (I just gave up at trying the remove option).
Please help this is going to drive me insane, plus when I click on the McAfee icon on the desktop it says that the subscription has expired, shouldn't that mean that it shouldn't have pop ups?!
Also, don't know if this helps, but the computer I'm using is a Lenovo.

Uninstall it

By turning it off at your own risk

OR

better still, stop going on websites that are questionable or dangerous.

If you turn off McAfee, and go on these websites, you may end up with a computer that does not work any more.

It can be quite costly to remove these viruses and other malware.
