Download our award-winning, free antivirus for PCs.

Yes. Plus, viruses are far from the only type of malware you might encounter. Malware has many faces and gets spread in different ways, whether it’s blackmailing with ransomware, spyware monitoring everything you do, or a Trojan that’s hidden in your PC software. There are other kinds of dangers too, such as unsecured public Wi-Fi hotspots, which are often used to launch cyberattacks. Also, when you go online, phishing websites can target your online account login details.

With this in mind, it makes a lot of sense to have a Windows PC with real-time antivirus protection that helps you regularly scan your computer for malware. Avira Free Antivirus for Windows uses advanced AI technology, cloud-based cyberthreat detection, and thorough virus scanning to provide you with a comprehensive defense. You also get a browser safety extension with phishing protection to block potentially unsafe websites, plus a software updater to keep your PC apps safer from security vulnerabilities. To add, our virus definitions update automatically.

Click the free download button to get Avira Free Antivirus. Open the downloaded file and follow the installation instructions. Once installed, system protection runs automatically in the background, but you can turn it off temporarily if you want.

You’ll need to start the virus scanner manually, which runs in the foreground. You can run a quick scan to check the most vulnerable areas of your device or have your entire system checked with a full scan. You can also run preset or custom scans and schedule and manage your scans.

The convenient Smart Scan feature allows you to check your device for cybersecurity, online privacy, and performance issues with just a single click. This is all thanks to our free Windows protection solution. The latter offers much more than just an antivirus program.

Yes. Avira Free Antivirus for Windows is available to download for nothing. The antivirus protection program for your PC uses the same antivirus scanning technology as Avira Antivirus Pro for online protection you can count on. The Pro version for Windows has additional features. This includes web protection and the Avira Firewall.

Our free antivirus app for PCs, Avira Free Antivirus, is available as a free download for most computers running Windows 7, 8, 10, or 11. We also offer free online protection solutions for your mobile devices in the form of Avira Antivirus Security for Android and Avira Mobile Security for iOS.

Yes. You can easily get free antivirus software for your laptop or PC. The key thing is to choose an app from a reputable brand, especially one with award-winning credentials that you can really trust. At Avira, we offer a reliable, free Windows antivirus of our own that gives you real-time protection against various different kinds of cyberthreats.

Windows offers basic antivirus protection with the pre-installed Windows Defender app. Unlike Avira Free Antivirus for Windows, it does not have additional cyber protection levels and online privacy features. These include a free VPN, a password manager, a browser safety extension with phishing protection, and a software updater that updates third-party PC programs to help prevent security vulnerabilities. That’s why we recommend using our free antivirus protection app, Avira Free Antivirus, on your Windows computer to boost your online security.

Windows Defender doesn’t conflict with other antivirus programs. But it’s best to only have one antivirus program running. This is to stop multiple security apps, running at once, from impacting your PC performance. If you’ve installed other antivirus software, you can disable Windows Defender’s real-time protection temporarily. To do this, go to the virus and threat protection settings in the Windows Security app.

In short, there is none. In the past, we added various tools and features to our Avira Free Antivirus app. This included a free VPN, software updater, and some optimization tools. Plus, we added a password manager too. After this, we renamed this all-in-one antivirus software Avira Free Security.
