My OS is Windows XP Pro SP3 and I've used Sygate Personal Firewall Pro for years. Does Sygate still 'cut the mustard' in 2011... or is it ready for the knackers yard?
it hasn't been updated or developed for a long long time. My rule is not to use obsolete software but if you are content i doubt you will encounter some malware that will take advantage of your FW
you might want to take a look at this Google FortKnox Firewall used Sygate myself for several years this seems to be a updated version
