David or Kevin, I currently have Windows XP SP2 and both the
forewall/antivirus is ON. I performed a "shieldsUP!" test in www.grc.com and
the 23,80 and 443 ports are wide open. Linksys has verified my router and
appears to be in good condition (properly secure). What can I do to
close/stealth those 3 ports ? Please advise.
