True, a lot of peoples computer use is barely literate and very boring.

And yeah, all of my open ports are done so for programs that i trust and therefore would open for in the firewall as well. That still leaves a vulnerability however. A good firewall will know if its the allowed program that is using the port or not, though.

99% people do not do anything other than browsing and gaming. Then again, if downloading via a trusted p2p app, which keeps a port open, that is not an issue either and it does not require a firewall, since it would be allowed anyway.

If you are doing anything outside of simplest web browsing, you have open ports.

Note, that Windows keeps some ports opened, but they are just loopbacks.

Still going to stay with it as it is a stand alone and doesn’t need to do much more than it does alert me to who on my computer is calling home so I can decide to allow or block and been using computers well before Windows launched in late 90’s.
As you say we dont need your package unless lazy as our routers these days do a good job too so together with OA I’m good til 2020 running Windows 7.
So a firewall really doesn’t need input stands alone and with our routers now today also standing between OA firewall and the internet – we’re all safer than ever before too, so why change? So you dont make the case at all – in fact opposite.
I’m sticking with OA best firewall ever IMHO some say Comodo is but it is much more complicated than OA which is the best always has been. Shame on you – missing a business opportunity by not carrying on licensing it.
Could you at least let me know if you consider selling

Have used this same optical disc it’s on dozens of times to install the suite w/out issues & now OA warns me? Of course the amount of times the alert shows varies by computer, the above was the last & worst time.

It’s the job of installed security to detect installing malware loaded software, or that w/out a digital signature (Windows may also warn of the latter). I agree with the author on this, since many times we already have the software in hand, be it downloaded or purchased in-store.

One can take charge of their own NAT based Firewall built into most of today’s routers, the first of course is to disable remote administration, second to disable UPnP unless needed for a specific reason (I’ve got by w/out it fine for years). Finally changing the obvious name of the network, normally the make & model of the router, which is easily looked up to find weaknesses, to something that doesn’t let the neighbors & drive by attackers to know & exploit. Plus changing all of the default passwords to a strong, yet easy for the user to remember, adding a couple of the symbol keys (!@#$%^&*() to prevent a brute force attack. To include the wireless passphrase.

Turn OFF guest network option if not used, as one highly popular brand doesn’t allow the creation of a complex password to prevent brute force attacks.

Finally, change passwords every few weeks to months, depending on need & if guest access is needed, enable this option & disable once finished. Be sure that the Windows Firewall is active, when running any security, even Emsisoft Anti Malware. However if an Internet Security pack is used, such as Emsisoft Internet Security, the Windows one should be disabled. Note that some brands that says ‘Internet Security’ on the package doesn’t include a Firewall. Seems misleading, yet technically it’s not. It’s up to the consumer or business to ensure a Firewall, if desired, is included.

Taking charge of one’s networking goes a long ways towards their Firewall protection, at no cost except taking a little time when setting up the router, rather than just plug in & go.

High end BMW’s and Land Rovers with the latest in automotive security for example get stolen everyday and they paid a heck of a lot more than 3000 bucks. Security is not set and forget. :-) Ask the NSA.

Hope all this talk of Emsisoft Internet Security being a technological evolution, etc, doesn’t mean you are looking to abandon development of Online Armor!

Let us stick to formal: definition of give piece of your mind from U.K. English Cambridge advanced dictionary open source of course. P.S. my Japanese is perfect also. In the U.S. they say “love to have a piece of mind” but I agree with you English is best and is the correct use of the word. “Peace of mind ›a feeling of calm or not being worried: For my peace of mind, please check that the door is locked.” And now what do we do with a U.S. stroller because it is no longer a person who strolls, it’s a pushchair. And so on and so on and so on. ( ? ).

Interesting reply. In your last sentence you meant “peace of mind” for sure and not “piece of mind” unless you meant of course to say that you were giving us a “piece of your mind” i.e., your version of the working of a firewall in this case…Enjoy the day and thanks again for your contribution.
