Pinecone, I have known people who just use the built-in Windows firewall, however the downside is it does not monitor outbound traffic. I would like to think that most, but not all, people would agree that a third party firewall that monitors both inbound and outbound traffic is the best way to go. Regardless of how careful some consider themselves to be on the internet there is always that chance of getting infected by malware one way or the other that may try to 'call home' with your personal information. http://netsecurity.about.com/od/firewalls/a/aa081804b.htm "Is there any way to know for sure what I am changing?? " As Luis stated Zone Alarm will present you with a pop-up window letting you know that an application or program wants to access the internet. It will give you the option of 'Yes' or 'No' and list the application that wants access, such as 'Internet Explorer' or whatever programs you have. There is also a 'More info' button in the alert. If the program is one you recognize and use all the time, you can click 'Yes' and select the box 'Remember this info_______' to keep from being bothered with the same request all the time. If it is a program you don't recognize I would click 'No', but not necessarily select 'Remember this info'. If the request keeps coming up and you don't recognize the program and the 'More info' button does not give you the info you need you may want to 'google' and see what it says. There are some 'Windows applications' that need internet access on occasion. Witz

unfortunately it is extremely important so some way some how we will all have to do this. Here are articles to help you get an understanding on this DNS vulnerbility which the patch is for. The DNS converts the words you type in the address bar into a numerical address thatÂs used to route all Internet traffic. Exploiting an error like that would make phishing scams simple  people would think they were at their bank website and happily type in personal details, which the criminals could then harvest. Internet flaw could let hackers take over the Web Deficiencies in the DNS protocol Major DNS flaw could disrupt the Internet this is the site where you can find the DNS checker to have it run on your pc and see what it says about your system and how vulnerable it is. DNS Checker For those that are needing to completely remove ZA from their system many people are reporting using this program to get a clean full uninstall, it is a free uninstall program which works well to remove many programs that can tend to be hard to remove. I personally have not used it but several people on the tech sites are recommending it. Revo Uninstaller Zone Alarm also has detailed instructions on their site on how to do a clean uninstall should you need it.

I will rephrase. If your most recent install or update of an Adobe product came directly from the Adobe site, then I would view that as a trusted source and I would tell Zone Alarm to allow it. That's just my opinion. If that doesn't work for you then I would get in contact with ZA and find out how to get ZA to do what you want. On the other hand, if your most recent install or update of an Adobe product did not come directly from the Adobe site then it's possible that whatever you put on your computer is infected and Zone Alarm is trying to warn you. I would be very suspicious of installing anything related to Adobe from any source other than the Adobe site. So tell us...where did your most recent install or update of an Adobe product come from?

At this point, I wouldn't start swapping zones right now - it may just add more confusion. As far as relocating, the sensors can be sensitive to RF interference and, although they shouldn't be, temperature changes on the wall. But first, if you have the installation/service manual - not the owners manual - you can see if zone-4, or all the zones, are "supervised alarm zones/circuits." When I mentioned it may contain a resistor (end of line), it is because of supervised circuits. Supervised circuits, in simple terms, the alarm control panel is acting in a tri-state mode. It it always looking to see a certain resistance across the circuit; let's just say 1k, it's a NC circuit, and the resistor is in series. A cut of the wiring triggers a high resistance error and sets the alarm mode. Somebody who places a jumper across the wiring, triggers a low resistance error and sets the alarm mode as well. The resistor value that must be used will be listed in the installation manual. Since ambient temperature affects resistor values, placement on a wall heated by the sun could cause enough change on a high tolerance resistor to cause an error - but that's just in theory and there's usually enough tolerance in the system, but it could happen. A simple test to help determine sensor, wiring, or controller fault would be to first determine if this is a supervised circuit and it's resistance value. Disconnect zone-4 wiring, at the controller, and either jumper with the appropriate resistor (or just a short wire if non-supervised) and disable all zones but 4. Let it run for a couple weeks and see what happens. Just kind of flowchart logic from there. But actually, I also have another thought here. You mentioned zone-4 is master bedroom and home office, so I'm thinking a PC in the home office... maybe a UPS power supply? Maybe one with an "auto test feature?" I even had an APC unit that by default ran an auto test mode "about every two weeks" - now with the full cycling of the UPS, and it's temperature changes, that could possibly trigger an IR detector... just a thought.
