αμα δεν εχεις πολυ εμπειρια με φαιργουωλς uninstall το sygate

και δοκιμασε κατι πιο απλο ( outpost, zonealarm free) και μετα βλεπεις αν υπαρχει και εκει προβλημα.

 

σε εμενα σε 2 xp-sp2, στο 1 τα sygate kai tiny πετανε μπλε οθονες, στο αλλο παιζουν κανονικα. εχουν καποιο προβλημα με συνεργασια με προυπαρχον σοφτ, αλλα δεν το ψαχνω αφου υπαρχουν εναλλακτικα firewall.

 

επισης, τα software firewall, (εκτος των windows xp), προστατευουν και απο ΕΞΕΡχομενες κλήσεις (δηλαδη αν εχεις ενα spyware trojan, ή καποια προγραμματα που επικοινωνουν με τον κατασκευαστη για να τσεκαρουν οτι εισαι registered user).

αν δεν τα φοβασαι αυτα, το windows firewall σε προστατευει απο ΕΙΣερχομενες επιθεσεις αρκετα καλα (port scans, klp)
