I just found (via GRC and whatsmyip) that port 21 (ftp) seems to be open on my system.
this really surprised me as I have a NAT router (DrayTek 2800VG) on which I have no opened ports, and am running ZA on my XP Home SP2 system (windows firewall disabled in favour of ZA).
I seem to recall running these portscanners a while ago and everything was closed up tight.
I run AdAwareSE, SpyBotS&D & AVG and they've detected nothing.
If I run an ftp client against my IP address it doesn't connect ("unknown error number") .
Any suggestions from you security gurus who seem to haunt this place?
