When it comes to cyber security, most of us are already familiar with antivirus, anti malware, and anti spyware programs that keep various and sundry types of online nastiness off of our computer systems. However, a good firewall is also an integral part of any cyber security suite, as it protects against active and passive hacker attacks, as well as rebuffing other cyber intruders of various stripes. With a little preliminary research, you should easily be able to find a firewall out there that works with both your system and your budget.
To find the best firewall for you, a simple search engine query is a great place to start. A query that includes the name and version of your operating system, as well as the phrase firewall reviews, should return many pages of reliable, third party results. Pay especially close attention to those firewall reviews that are listed on professional software review sites, as these tend to be some of the most reliable sources online. Make sure that the firewall you plan to download is compatible with your operating system, and is consistently ranked highly in security and reliability ratings. And of course, do bear in mind that, as with most software, a good firewall can run the gamut of price points. Again, read the reviews carefully, as an expensive proprietary piece of software does not necessarily equal a better firewall.
Once you have downloaded and installed the firewall of your choice, have your firewall scan your system immediately to check for any holes, intrusions, or other cyber nuisances that can wreak havoc on your system. With any luck, your system should be clean, and your firewall should be able to identify, quarantine, and remove any suspicious pieces of software that slipped through cyberspace and onto your computer. Good luck!
