First off, I'd make sure my computer is clean and that Windows MovieMaker is actually clean by scanning with Ad-Aware SE, Spybot S&D, and Ewido Anti-Malware or A-Squared Anti-Malware. If Kerio Firewall continues to block MovieMaker, I'm sure that once you open up Kerio's main interface, there'll be someplace where you can tell Kerio to ignore all activity with MovieMaker.

You have started a new thread but I assume that you are replying to my message: /t157267-Kerio_blocks_Intrusion_by_Windows_Movie_Maker.html

I have scanned the machine with several of that applications and nothing was found. I have no idea where in Kerio one excludes this kinda of warning for this application. It is really annoying to have to continually click on the DENY button numerous times.
