I've never experienced any repeated connect attempts with P4. Before I set ZA to always allow it to connect, it would try once on launch and not after that, regardless of whether I let it through or not. As far as I can tell, it doesn't matter whether you allow it access or not but that's on dial-up with no network. I use the freeware Antivir AVS and havent experiencd any application conflicts. Norton seems to be a bit touchy.
