Pop ups to buy Performance Pro

I installed Protection Pro on my PC and laptop but keep gettiing Pop ups trying to get me to buy Performance Pro Tune up.  Is there a way to disable these please?

Hello David.

Thank you for contacting us. I have checked your account details with us and found you have purchased AVG Protection Multi device. You would have downloaded a trial version of AVG Performance from within Zen window. I would request you to purchase AVG Performance subscription too if you would like to continue using AVG PC Tuneup features and keep your PC in top shape. If you do not want to purchase it, please go to control panel and uninstall AVG PC Tuneup to stop the pop ups. Thank you.
