Hello I've finally decided to buy a firewall for my PC. For the record I have a P4 512 RAM WIN XP ADSL AV and a firewall on one of those 2-week trials. Now I don't want to influence your comments by naming the FW before you check out the scan results. Note I know virtually zilch about technical stuff - I just installed it with 'recommended config' and away we went. I have no complaints about it malfunctioning or anything. It's just I've read many times over (but don't quite understand) that stealth/blocked is good and closed is bad. So here are the results for the F/Wall from PC FLANKS set of tests:- QUICK TEST Danger! Trojan horse check Warning! Browser privacy check Danger! STEALTH TEST TCP "ping" non-stealthed TCP NULL non-stealthed TCP FIN non-stealthed TCP XMAS non-stealthed UDP non-stealthed BROWSER TEST Cookies Red sad face Referrer Red Sad Face TROJAN TEST 34 Closed Ports ADVANCED PORT SCANNER Standard Scan 4 Stealthed 9 Closed 1 Open TCP SYC Scan 5 Stealthed 8 Closed 1 Open EXPLOITS TEST A Green Smiley (at last) As you can see its got lots of closed only ports etc. People seem to brag that their FWs are all blocked. Are these results OK or do I need to fine tune it with other members' guidance or try another FW?
