HIPS goes crazy with Steam

HIPS goes crazy showing pop-up after pop-up when I start Steam. I click to allow and remember but it just keeps poping up a new alert until I give up and turn off HIPS. I’ve gotten serious problems with Steam and a game called “Counter-Strike Nexon: Zombies” which appears (when judging from CIS reactions to it) to have been compromised by hacking, so I can’t use it anymore.
