With Kaspersky's new AntiHacker program with stealth mode activated I am failing PC Flanks Stealth-Test!!!! All 5 mini-tests are all coming up negative - ' all non-stealthed' and the recommendation is to switch to another firewall!!!! The site is recognising my correct IP address and AntiHacker passed all the other tests on the site and the two tests on 'Shields Up'. I have not tried more extensive testing as I was quite alarmed by the negative results at Flank. The WinXP firewall is switched off. Is the stealth testing procedure over at PC Flank reliable or is it simply something I am doing wrong? Overall can people suggest testing sites they would recommend for testing of the reliability of their firewalls?
