There are many firewalls currently on the market, and while many of them advertise that they offer the best protection available, this is obviously true of only one firewall, as you cannot have many different firewalls that are the best. It is hard to decide which one offers the best protection just by reading the descriptions of various firewalls. The best way to decide which firewall can protect you the most is to conduct a test. Such tests were done, and I am going present you with the top five results:
Comodo Firewall Pro (95%)
Outpost Firewall Pro (91%)
Online Armor Personal Firewall (89%)
Kaspersky Internet Security (85%)
It is interesting that the top two firewalls are actually free, and to have the best protection you do not need to spend any money. From the commercial firewalls it seems that Outpost, Online Armor, and Kaspersky are the best choices. From this list I would recommend Kaspersky. These days there is a lot of malicious websites that contain malware, so using a reliable firewall program is a must. However, the results prove that even those who do not have a lot of money to invest in protecting their computer can still have great protection. This is especially true if they do a little bit of research before deciding which firewall to use.
