I have been using Zonealarm for a while under Windows98 and have just installed it on a Windows 2000 machine.
However I keep getting lots of pop-ups via the messenger service. I don't really want to disable this service, but think it seems odd that my firewall is letting all this traffic through.
I will have to look deeper into the settings, but I also think that Zonealarm is let down by its annoying hard to use interface, that has buttons hiding all over the place.
Does anyone else have this problem?
