comodo firewall as gone mad just after i just installed comodo backup

no antivirus module is installed. i have just restarted after comodo backup install then enter my id and password, the comodo firewall started to scan all my files main taking much time with big files like netbeans intallation and a bunch of large files (200mb+) now it have like 20 mins on it,(actua;;y still on it)
i have takend some memory dump of comodo backup applications (cuz is frozze like waiting for comodo firewall to finish scaning) to make a bug report if asked

edit: i just see it is comodo backup who is scanning endlessly, i wonder why, it is not and antivirus, anyway if it takes more than 1 hour i will uninstall it
