ZA needs to put this disclaimer on the site before you DL. I get so many emails from friends that are freeking out after they install ZA because of all the IP blocks they are getting. I'm tired of explaining to each one.
Also Zone Alarm is good with NT but only if you use it 100% of the time. I got to where I turned it off every now and then, and it would shut down my internet connection. And I was told the same from many on NT newsgroups.
If the people would click the link zonealarm provides, it is a very thorough and simple explanantion of what the port scans are. Personally, I don't worry about them, because if ZA logged it, then that means the attempt was un-successful. I have had two that piqued my interest as I stated above. The one from the "Investigaciones de y Internacionale" (I'm doing this from memory, so the exact name is probably a little diffrent from this) listed in Mexico city actually sent a little paranoid tremor through me. I can't figure out why a place like that was trying to scan me. Anyway, there's probably nothing to it, and this is probably just a fancy name for a data mining firm, bug I still wonder about it.
The first time that happened to me at home, I thought it was the connection somewhere on the hardware. Spent 10 minutes going through the connections, then decided I would start up ZA and try again. Internet popped right up. Considered just removing ZA but considering some of the interesting places I've received pings from lately I'll keep it running
