PC freezes when starting rFactor

Hi all,

Recently there was a update for a racing game called rFactor (http://www.rfactor.net). Before the latest patch I had no problems with rFactor and Comodo. But since the last update (1255F), my pc freezes if I start rFactor.
After making a topic on Race Sim Central, I was advised to un-install comodo. When I did that I am able to start rFactor with no problems. To be sure it was Comodo I installed the firewall again, and the problems started again.
So can Comodo bring some kind of hotfix ?
