If you run ZoneAlarm free edition version 6 then note that the update checker does not seem to find version 7 which has been available for a while and you need to download and install this separately. Just noticed this myself recently.
On the subject of ZA free, what settings do people reccomend. I only want the firewall functionality as Im happy with my current AV and ASpy arrangements.
I generally just install ZA, leave it set at the default settings, clear the allowed program list from time to time and then just allow or block individual applications (and remember the setting) thereafter. ZA of itself doesn't perform anti virus/spyware tasks.
A colleague reported the srescan BSOD with ZA7. He has switched to [broken link removed]as a result. No experience of it myself but I see that [broken link removed] which would, in my opinion, inspire confidence.
