A firewall is probably best described as a software application that stands guard over your network. Since users may at any time connect to the Internet, the firewall needs to be able to go up at a moment’s notice if it appears that an undesirable file is about to infect the network. Take for example the viruses which are notoriously spread by email. It is the job of the firewall to recognize the threat before it occurs and erect a virtual barricade that will not permit the infected file entry into the system.
Fortunately for the average computer user, it is no longer just the corporate networks that are being protected by a firewall, but instead a person firewall is now also available for the home PC. Once again the firewalls will monitor communications to prevent access by infected communications. While many a firewall software is commercially available, there is also some free firewall software that may be downloaded by the consumer. Free firewalls work just as well as their commercial counterparts, and it is up to the consumer if the few extra bells and whistles usually offered by the commercially available package are worth the money. While it is not necessary to run a firewall test on your free Windows firewall, it is advisable to periodically check that the application is indeed enabled. Similarly, keep in mind that the best firewall is the one that is periodically updated and if you find yourself prompted to download the latest version of your free personal firewall, it is wise to pay attention to the notice and actually go ahead and do so. A firewall free of charge should still offer you periodic updated. If you find that this is not the case, then it might be best to look around for another provider. There is a plethora of websites dedicated to the review of the best free firewalls on the Internet, and oftentimes it is the consumer who gets to rate the software and share the experiences they had with it. Sometimes these experiences showcase that the software is too complicated for use of the average PC aficionado, while other times they clearly state that certain types should be run by those in the know about such programs since they require heavy customizations. Probably the very best software to run is also the simples – and this one is usually bundled together with a good anti-virus protection software package.
