We currently live in a time where keeping your computer secure is more important than ever before.

Viruses are now extremely advanced and can penetrate a system with consummate ease. Having the right Antivirus protection can literally be the difference between having a working computer today, and a broken one tomorrow.

With that in mind, we thought now would be a great time to showcase what we believe are the best free antivirus software options currently available. I mean, who said protection had to cost you money? Well, maybe organized New York crime families. But that, thankfully, is another story altogether.

Antivirus software manufacturers now provide superb protection from malware, spyware, and adware, for literally no cost what so ever. Before we go into any further detail regarding the features and benefits of antivirus software, let’s take an initial look at the contenders.

The Best Free Antivirus Software
WePC Awards Best In Class

Avast Free Antivirus

Avast Free Antivirus

Editor's Rating
★★★★★ 4.7/5
How we review
Pros
Cons

Avast’s free antivirus software package has been praised for as long as I can remember and sits high on the list of best free antivirus software options. It offers a lot of free features that other antivirus packages class as premium. Some of the features included are; Online security, a password manager, Wi-Fi inspection, several scan options, phishing and malware protection, and more.

This package gives you almost everything you’d need from the free version. However, if you are looking to splash out on some additional features, the Pro version offers a full array of extra addons.

The Next Best Free Antivirus Software

Kaspersky Free Antivirus

Pros
Cons

Kaspersky free antivirus software is one of the most watertight package options available. It’s one of the only antivirus software packages that scored near perfect in the independent tests as well.

It comes with a bunch of cool features which include malware protection, spyware protection, general virus protection, multiple scanning choices, URL blocking, and much more. Many of the features displayed in the free version are considered premium also.

Kaspersky doesn’t take up too much computational power, which makes it great for people with slower than average computers.

Overall, a nice little antivirus package that sits right up there with Avast in our best free antivirus software packages.

03
Another Great Free Antivirus Software

Bitdefender Antivirus Free Version

Bitdefender Antivirus Free Version

★★★★★ 4.5/5
How we review
Pros
Cons

The main draw of Bitdefender’s free antivirus software is the excellent virus protection it provides. At its core, it offers the same amount of virus protection as the paid version. So what’s the difference I hear you ask? Well, that’ll be the features.

Unfortunately, Bitdefender free doesn’t come with any premium-level features, unlike other free antivirus options. That being said, it does offer premium virus protection overall.

Another great reason people choose Bitdefender comes down to the computational power it uses. Well, in this case, I suppose you could say doesn’t. Compared to other antivirus packages, Bitdefender uses very little power. You can have this thing running in the background, and you wouldn’t see any difference in your PC’s performance.

Ultimately, if you’re looking for simple, solid protection, this might be the pick for you.

04
A Very Popular Free Antivirus Software

AVG Antivirus Free Version

AVG Antivirus Free Version

★★★★★ 4.5/5
How we review
Pros
Cons

AVG has been a huge player within the antivirus game for as long as I remember and was my goto choice for a paid virus protection. It is by far, one of the most popular antivirus solutions available thanks to its high test lab scores and excellent overall protection.

It includes features such as real-time scanning, malicious URL filtering, a great antivirus engine, and more. It also comes ad-free!

The user interface is classic and one that is very self intuitive to use. Unlike other antivirus software packages that can seem quite technical, the AVG package is really easy to navigate and use.

A great antivirus software package that has everything you would want from a free package. However, it could use a few more features if truth be told.

05
A Free Antivirus Software With Great Overall Results

Avira Antivirus Free Version

Avira Antivirus Free Version

★★★★★ 4.5/5
How we review
Pros
Cons

Avira might be news to you when it comes to the best free antivirus software, but I can assure you, it’s a great overall package none the less. Even though the Avira antivirus software gets good independent lab scores, it still falls a little short of others on this list.

It does very well in the hands-on malware blocking tests and does a great job of alerting you of any malicious URLs. The user interface is very simple to use and is self-intuitive. That being said, the Avira antivirus package comes with a few downsides, respectively.

You only get browser protection for Chrome and Firefox, unlucky Microsoft Edge users. It can also be quite slow in the scanning processes.

Other than that, it’s not a bad little antivirus package and one that might suit your needs perfectly.

Final Word

So, there you have it, our comprehensive breakdown of the best free antivirus software currently available. If truth be told, most of the packages have very similar features and benefits. However, they do differ slightly.

Some have more efficient power usage, and some have a more intuitive user-interface. But at their core, they all offer excellent virus protection for your home computer.

Ultimately we have ranked the Avast antivirus software as the number one free pick because it simply offers the most in terms of performance and protection combined.
