Comodo Crash!!!!!

6/6/2009 7:58:53 PM C:\WINDOWS\system32\drwtsn32.exe Terminate Process C:\Program Files\COMODO\COMODO Internet Security\cmdagent.exe

Happened will I was scanning with anti virus and allowed update. I dont know if it was a AV issue. But when I closed it, the GUI seemed to still be there except the AV had closed, I unplugged the network cord and restarted, was my computer vulnerable to any security threat during that time. and is this problem anything to worry about, did my firewall actually crash and leave my computer exposed or was it just the AV, do I need to re-install?
