At Avira, we believe that everyone should enjoy a safer and more private digital life—anytime, anywhere. That's why we provide free software for your online security and privacy, plus performance enhancement—for Windows, Mac, Android, and iOs devices. Our Avira Free Antivirus is a great place to start if it’s just free software security you’re after: It offers cloud-based, real-time protection to help block a huge range of online threats and malware, including the latest viruses, Trojans, and ransomware.

If you love surfing online, consider this free, discreet add-on that helps secure your browsing and can protect your privacy: Avira Browser Safety (for Opera, Firefox, and Microsoft Edge) was designed to shield you from dangerous and phishing websites, malicious advertisements, and online tracking. It highlights infected sites in your search results, so you’re forewarned. Plus, its anti-tracking capabilities can help prevent ad networks from monitoring your online activities. It also helps stop potentially unwanted applications (PUAs) from hiding in your downloads—once inside your system, they could spy on you or display an annoying stream of ads. Google user and online shopping fan? We have something for you too. Avira Safe Shopping offers a price comparison tool so you can still grab a bargain and rest assured it’s from a trusted site.

Avira Phantom VPN encrypts your data traffic, helps anonymize your online activities and lets you surf more securely, even on public Wi-Fi. VPNs create a virtual private ‘tunnel’ through which all your online data is passed, where it’s safer from prying eyes and cyber criminals.

Now you know how to stay more secure and private online (for free!), but what about device performance? Avira offers numerous cleanup and optimization tools to help you speed up your machine and free up more storage space. Now how about freeing up your own mind from the hundreds of passwords its struggling to remember? Avira Password Manager creates and stores strong passwords for all your user accounts. For peace of mind that you’ve got all your (virtual) bases covered, there’s this: Avira Free Security contains the free Avira tools as a single, practical solution. With just a few clicks, you can check your devices for security, online privacy, and performance issues—and fix problems fast.

Stronger security and revved-up performance with our premium solutions

Our free security software offers essential tools to help optimize and protect your digital life. For example, the free Antivirus for Mac and Windows uses the same powerful virus scanner as our premium version. However, our Pro versions unlock additional features and enhanced levels of protection, such as a VPN with unlimited data volumes (limited to 500 MB per month in the free version). With Avira Antivirus Pro for Windows and Mac, you get built-in web protection and advanced anti-ransomware. Plus, there are no ads.

Avira System Speedup Pro for Windows offers a wider range of tune-up tools for more thorough and automatic cleaning and device acceleration. Avira Internet Security offers multiple premium products but has a few more things up its sleeve than its free cousin, Avira Free Security: In addition to the advanced protection features of Avira Antivirus Pro (such as download and email protection), it also includes Password Manager Pro which can alert you if your data has been leaked in a breach. Plus, there’s Software Updater Pro, which allows you to automatically update your programs and drivers. Explore the differences between the Free and Pro versions here.

If you truly want all that Avira has to offer, there’s Avira Prime for the discerning, even more security-conscious user. It’s our most comprehensive offering and runs on up to five different devices. This premium all-in-one includes all our Pro features for more security, online privacy and performance.
