Avira Free Antivirus is one of best free antivirus software programs out there for various reasons, the least of which is just because it's free.

My favorite feature of Avira Free Antivirus is the wide range of malware threats that it protects you from. I also like how simple the interface is.

Important: Avira Free Antivirus provides free on-access or resident protection, meaning it's keeping an eye on things all the time.

Because of this fact, Avira Free Antivirus can completely replace any antivirus software that you might be paying for, like popular products from McAfee and Norton. Some of those programs might be offering you other services but as far as malware/virus protection is concerned, Avira Free Antivirus does the same job... for free.

My Thoughts on Avira Free Antivirus 

Avira Free Antivirus is an excellent free antivirus choice. While not my favorite (I prefer AVG, avast!, or MSE), it certainly has its pluses.

As I mentioned above, the best thing about Avira Free Antivirus is the range of protection - everything from old fashioned modem dialers that used to rack up the phone bill to the most advanced Trojans.

While this might seem odd to mention, the configuration wizard, which I listed as a con, is actually quite handy as long as you know what you're selecting. For example, one option allows you to choose whether to start Avira Free Antivirus early in the Windows boot process, giving you greater protection, or later in the process, providing a bit less protection but speeding up your boot. Options are always good, right?

Tip: You're asked to register after the Avira Free Antivirus installation, but it's optional. Also, if you'd like to prevent browser toolbar and settings changes, choose the Custom Installation option and unselect those options.
