How To Block.....?

Not only am I a novice to much of this, but I’ve only just gotten Comodo recently.

AIM is trying to get me to update its messenger. I keep getting a Really annoying pop-up every 10-15 mins. or so. (makes my pc game crash too)

I suppose I may update it eventually, but in the meantime, is there a way for me to block that pop-up from springing up on me??


What popup is this…whats it’s saying?
