Need an opinion here. Do I need ZA behind my router?

While it won't hurt anything, it also won't really do you any additional good. Protection from firewalls does not stack, in that two firewalls give double the protection of a single one.

If you ever use this system from out behind your router, it might be prudent to keep a software firewall around for those times, but it's little more than a drain on system resources otherwise.

That's kind'a what I'm thinking. . .

I run AVG and the rest of my Anti-Parasite Suite. This is the wife's new PC BTW. I'll watch it for a while. If all goes well I may remove it from the rest of the PCs on my home network.

I remember a time when a firewall was essential on a PC just connected to a modem. But not today behind a router and proper precautions are taken.

Router & ZA firewall

I'll not argue the point. However, I ask this question. Does your router have two way checking? Does it check incoming (yes) AND outgoing (probably not). You would be wise to use ZoneAlarm in conjunction with that router as it checks both ways.

Yes.

All it takes is some pest to invade one machine and it will turn and attack it's neighbors.

IF Multiple Machines On The Network.. Yep...
by Grif Thomas Forum moderator / August 2, 2007 5:08 AM PDT

If one computer contracts a network-aware worm, it will transfer to all machines on the network unless it's blocked from doing so. For example, when the Blaster worm was released a few years back, for those portions of the agency that weren't patched correctly, the firewalled computers were the only ones that weren't affected.

Hope this helps.

Router or Zone Alarm
by Joseph Petrini / August 3, 2007 1:54 PM PDT

We have routers at both the office and home, but I'm concerned as you are about security. I purchased Zone Alarm about 2 weeks ago and would recommend you try any other protection you can find. Zone Alarm has 2 processes that run and use 100% of the processor most of the time. It does allow you to stop a search for updates, but does not permit scheduling them, when the Zone Alarm program is downloading and installing updates, it freezes my computer. Last night I finally uninstalled it. For analysis & comparison I am running Windows XP, have 1 gigbyte of Ram and the processor is x86 Family Model 13Stepping 6 GenuineIntel ~2098 Mhz (I think that means 2 Ghz)

You need a firewall coming and going...

I spoke personally with a techie from Linksys, and while their router protects what goes out, you must protect what comes in!!!! Double protection, double the unhacked fun.

I run a Linksys Wireless-G broadband router behind a Linksys Broadband router which is behind a Linksys cable modem. Software firewalls (Zone Alarm) are installed on every computer (five computers) on my home network. And I run current A/V on all.

I like to watch the "In/Out Traffic Monitor" in the lower right corner of my screen. When I see unexplained traffic it is time for me to worry.

I guess I have overkill......

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
