The best free antivirus tools for Windows and Mac

It’s fair to say that an antivirus should be one of the first software you install on your computer. If you’re running Windows, the built-in Defender doesn’t provide the most reliable protection. And if you’re running MacOS, don’t believe the myths that Macs don’t get infected by malwareFortunately, it won’t cost you a fortune to get good antivirus protection. In fact, it won’t cost you anything. Below are some of the best free antivirus solutions that are available for both MacOS and Windows.

The best free antivirus for Windows and Mac

1. Avast Free Antivirus

The free edition of Avast! Antivirus is a reliable security software. The headline feature is as solid as you’d find in any endpoint protection solution, and it provides tools for scanning the file system, email attachments, and web activities such as webpages, downloads, and Javascript files.

Avast recently merged with AVG, and now both products enjoy the added benefit of a shared user base. That provides more data about new threats, which means they’ll be even better at protecting you against emerging threats.

In addition to its excellent anti-malware protection, Avast also offers peripheral protection tools, including a network security scanner, password manager, and secure browser. Avast also has a game mode that will avoid displaying pop-ups while you’re playing.

2. Sophos Home

The Sophos Home free antivirus sports some features that are usually found in commercial solutions. Sophos provides run-of-the-mill malware protection, both in real-time background mode and on-demand with impressive results. The anti-phishing feature works by blocking blacklisted URLs and scanning incoming HTML content for possibly malicious content.

One of the features that makes Sophos Home stand out among other free antivirus solutions is its cloud-based option. A single free account can be used to secure up to 10 devices, and you can use the online Home Dashboard to monitor and control your computers for alerts or perform scans remotely.

3. Avira Antivirus

With hundreds of millions of users worldwide, the Avira free antivirus is very popular. While speed is not Avira’s forte, its malware protection is quite impeccable. The mail and web protection, as well as its game mode, are disabled in the free version, which is a bit of a disappointment, given that other solutions offer those features for free. However, Avira free edition has a Browser Safety extension for Chrome and Firefox that fends off malicious and fraudulent URLs.

Avira’s bonus features include a free VPN service limited to 1GB monthly traffic on a single device, as well as two privacy features it has borrowed from Electronic Frontier Foundation (EFF): Privacy Badger and HTTPS everywhere. The former prevents online ads from tracking you and the latter enforces encrypted connections to websites wherever possible.

Bitdefender is especially good at detecting and blocking phishing, as well as malicious and fraudulent websites.
