got a cafix.exe popup first time ever when updating, is this legit

I was warned by microsoft security center that my antivirus software need to be updated. yet, the yahoo security suite didn't mention it at all. I updated anyway but for the first time got something called cafix.exe. I don't know what is it, and it was a popup warning from zonealarm eventhough all the other updates and functions are allowed for ca I know this is a new one but am unsure what to do. Anyone have any info on it?

 

Dont worry about that. Allow it connection as it is a fix for computer asscociates antivirus updater so that when it updates it does not need to reboot everytime as i found a bug whre i would update once-fine, second time it updates it would keep erroring out until my pc was restarted. This is a fix for the update problem. And i think it aids the system in updateing. But you should allow it because it is part of the updater.
