Previous security checking when I was running Ver 3, using the tester GRC.COM (SHIELDS UP), gave Comodo 100% pass.
My first retest since going to Ver 4 failed my Port Scan security as Port 0 and Port 1 are only CLOSED but not STEALTHED. Can I fix this vulnerability?
hi,
anser is No, only devs can fix it, its a old comodo problem somtimes reappering in one version and disaapearing in other versions

Umm I have no such problem with the current version 
Sometimes a malware that goes undetected or a trojan perhaps could cause things like this
