i am running kerio firewall. just now when i turned on my pc i noticed kerio started asking me again for program permissions. when i looked in the admin settings all of my program permissions were gone. it was like a fresh install of the firewall. have any of you noticed this behavior before with kerio or any other firewall? i did a virus scan and it came back clean. i have system restore turned off, the rest of my programs are as they always was. kerio was the only thing that changed. is there a type of virus that could cause this and not be detected by mcafee? my pc is password protected, and im 100% possitive no one has been on it since i was on it last.

im running win xp pro
mcafee virus scan 2004 completely updated

any ideas?
