I have Zone Alarm Free installed on my winvista system. While online I received a message form my firefox browser; "connection lost, the session was reset", then one of zone alarms programs permission alerts, to allow or not allow a program web access, followed. The zone alarm permission alert was: "svchost is trying to access the internet, would you like to allow this?" I clicked no since I had done this many times before with no problems. This time I could not regain a connection. Then I went into zone alarms programs tab and clicked "allow" for all items except server permission with regards to svchost. Should I allow svchost server permission? I believe svchost is part of the windows oper system so I'm guessing it's ok to let it have sever rights. I tried to post this at the zone alarm forum but the create an account page would not let me create an account (said my username contained irrelevant data?). Anyway, in the meantime I'm using windows firewall. Thought I would ask here before messing with it for the time being. Is windows firewall as good as a third party firewall? Any ideas? Thanks for your help.
