Hello Chestnut,
SONAR is indeed a component of your Norton product. It is essentially a heuristic engine that analyzes file and system behavior to identify "threat" like activity - the technology was covered pretty well in this ComputerWorld article.
As to the detection you getting from Zone Alarm, I believe this would be "normal" behavior when you have two real-time anit-virus components from different vendors. If this is the only indication of a problem you've witnessed, I think you can safely ignore ZoneAlarm's message.
That said, there are ways to use the products together, but ones that do essentially the same function can cause performance and stability problems. The primary components that generally don't mix well together are the firewall and anti-virus real-time (ours is called AutoProtect) features.
Thanks for posting,
Matt
The best thing you can do is either uninstall Norton or ZoneAlarm.
I would recommend uninstall ZA and just run Norton. They are listening great to their customers and there are some great things coming up
To everyone who replied:
Thank you very much for your thorough and prompt response. I'm very impressed by your depth of knowlege. I was advised to run Zone Alarm as a fire-wall protection and Norton for its antivirus properties by a technician who worked for my previous internet provider. I had installed Norton at that time, but when he examined my computer, he said that there was no fire-wall, so he advised me to acquire Zone Alarm. The two programs have cohabitated for over two years without a problem. I'm quite happy with the Zone Alarm pop-ups because I feel that there really is a constant guard at the door. That said, I have noticed a steady decline in the speed of performance in my computer which I attributed to a nearly full hard-drive (35 of 40 gigabytes). If I remove the firewall from Zone Alarm, how does Norton compensate?
Again, thanks to all four of you. This is a mysterious field for me, where I have a serious lack of fundamental knowlege. So your advice is greatly appreciated.
Sincerely,
Chestnut

That depends. I see in your previous post that a technician said you had no firewall. Is that because you were just running Norton Antivirus and not the complete Norton Internet Security Suite?
If you are running just Norton Antivirus, this does NOT include a firewall.
If you are running Norton Internet Security, then you have very effective Firewall Protection (if you have it enabled).
Phil- I am running only NAV2008. I have been advised on here not to run another firewall as the NAV2008 has an inbound firewall. I have been advised to not use another company’s firewall other than to upgrade to NIS 2008
Forgive me but I'm new to both this board and this method of obtaining information. That said, I apologize if I'm posting the the wrong place. I am running both Norton and Zone Alarm Security Suite. The latter often displays the following warning:
SONAR Component is trying to communicate with
C:\Windows\sysems\ZoneLabs\vsmon.exe
by opening COH32.exe .
It often happens when I run a Norton scan. Is SONAR Component part of your poduct? If not, do you know what it is? If not, could it be malicious?
Thank you for your help.

NY1986,
I stand corrected. You are right that NAV2008 has an inbound firewall.
Thanks for pointing that out to me.
I personally prefer the two way Firewall in NIS 2008.
Best Wishes.
Phil. I wasn't trying to throw you under the bus :)
Just wanting to make sure that I was pretty well protected (I know NIS will give me more protection)
NY1986,
Don't worry about it. I wasn't offended by your pointing that out to me.
I like to think that we all learn something new from these forums from time to time. It helps us all give more accurate information and help to others.
aha
I thought you were running NIS next to the ZoneAlarm suite.
That's not advicable but NAV next to the ZoneAlarm firewall is possible although some people do have problems.
I would suggest upgrading to Norton Internet Security or run Comodo firewall next to NAV
Chestnut,
I assume you are running Norton Internet Security 2008 since you did not specify the Norton Product.
First the good news. SONAR (Symantec Online Network for Advanced Response) is a legitimate component of NIS 2008. It protects against malicious code before standard virus and spyware detection definitions have been created. In other words, SONAR keeps you a step ahead in protection.
Now for the bad news, you should not be running Norton Internet Security 2008 and Zone Alarm together. You are creating a scenario for some serious conflicts. I am curious as to why you would want to do that. I have been using Norton for many years, and have never been infected. If you research the topic on the internet, you will see that it is bad practice to have two security suites running together.
I highly recommend that you uninstall all traces of Zone Alarm. Otherwise, you are heading for trouble down the road. Additionally, by running two suites you are consuming way to much of your computer's resources.
Best Wishes
Phil
