Many more free antivirus software products will be added to this page throughout the year!

The range of top free antivirus software downloads available for your Windows system might surprise you. The antivirus software offered for free by Comodo as part of their free Security Suite is possibly the best antivirus software product available at any price. A number of years ago Comodo made the decision to help everyone improve their internet security by offering a number of amazing products for free. Comodo decided to create a smooth performing security suite by combining their top rated free anti virus and free firewall security products. Comodo Internet Security finds and removes viruses from desktops and even networks protecting in real-time using proactive heuristic analysis to intercept unknown threats. Comodo can block malware before it has a chance to run by using host intrusion detection. Comodo is updated daily with the latest virus definitions. In addition to Comodo we like the free antivirus program from PC Tools called Antivirus Free Edition. Registry Mechanic and Spyware Doctor are two well known products from PC Tools. PC Tools in contrast to Comodo also has a paid version that adds faster updates and live support. The free antivirus product from PC Tools is updated frequently and actually protects in real time. Deep virus scanning power is a key feature of PC Tools Antivirus Free Edition to allow you to be confident of your virus protection. These security products both work with Vista.

Over the last couple of years quite a few of the
free firewall downloads have vanished from the internet. This change really does not matter because the best two still are available. Zone Alarm Free Edition is considered by many to be the best single function free firewall available. Many firewall reviews have listed this as a number one choice for many years. ZoneAlarm is so popular and works so well that it practically defines the entire firewall class. Even with all of that, I can still say it is not my first choice. You cannot find a better firewall than the one included in the free Comodo Internet Security suite. While a good basic firewall, ZoneAlarm Free is lacking some of the advanced whistles and bells that its for pay siblings sport. Comodo Firewall although free has the best features and functionality of ANY available firewall. When it was available as a separate firewall many critics reviewed it as the best firewall available. Now that it is integrated in a smooth functioning suite with Comodo Antivirus, it is even more appealing.

There are quite a few great
free antispyware software downloads available for your Windows computer. While many internet security products can only be run as one per class, antispyware often works best with two or three running at the same time. One of our computers has Spybot, Windows Defender and Spyware Terminator all running to prevent spyware issues. These three antispyware programs have been performing perfectly together for over a year.
