Quick ZoneAlarm & AV questions

I just installed the free ZoneAlarm firewall, and I was wondering...I don't have a home network, really, just one PC that's hard-wired to my cable modem, printer, and other stuff -- no wireless, either, usually, though occasionally I'll plug in a wireless router when I need to work from home off my office laptop. So my question is, when ZoneAlarm asks me whether my ISP should go into the "Internet zone" or the "Trusted zone", what should I say? Right now I've got it on "Internet zone," but I don't know if I'm being overcautious or if that's what it really should be set to.

Also, I've installed the free Avast! antivirus -- any special settings I need for that? I don't think it has a "gamer mode," so should I shut down resident protection when playing CoH or leave it on?

I'm also planning on getting Malwarebytes resident protection (one-time cost of $25). Any settings advice on that? (Do I even need that, or should I just do weekly scans with the free version?)

Thanks in advance for any advice!

I haven't used ZA in a long time so can't help there but Avast can run continually. Go to troubleshooting - and set check for full screen apps before using popups. Not familiar with the third one. I run Avast free version every two days.

Definitely put your Internet connection in the Internet Zone, otherwise ZA will do hardly anything.

We've been saving Paragon City for eight and a half years. It's time to do it one more time.

As long as the adapter/adapter subnet used to connect to the internet is listed under the internet zone you are fine.

The only thing you should have as trusted zones is dhcp, dns, and loopback along with internal computers as part of your home network behind a router. As you stated you are not networked,so you do not have to worry about that.

As for Malwarebytes, my understanding is the purchase version is not really worth it. I run the free version once every couple of weeks or simply when I think something is amiss.
