Avira Free Antivirus offers award-winning protection and it is free forever. With over 30 years of security experience, Avira offers superior detection, with additional web protection and repair capabilities. And as a German company, we don’t track what you do or sell your data to third parties.

Avira’s free antivirus software uses the latest cloud technology to offer you the fastest and most reliable real-time scanning and data protection. The fingerprints of new unknown files are automatically uploaded to our cloud and analyzed in real-time. This way, we protect you from Zero-Day-Attacks, where cybercriminals use new methods to infiltrate your system. Our Protection Cloud can detect these never-seen-before attacks. Once a new thread has been identified, you are instantly protected against it.

Real-time protection & repair

We protect you from billions of malware attacks annually, including against ransomware, Trojans, worms, viruses, and more. In addition to virus scans, our antivirus software includes advanced repair functionalities, fixing over 90 million files last year.

Light and fast

Avira has one of the smallest footprints in the industry – with virus definition updates 2-5 lighter than most other antivirus products. Unlike many others, our protection doesn’t slow you down nor hog your system’s resources.

Real-time updates via the cloud

Stronger together: every secured device is as a sensor, which detects emerging, never-seen-before attacks. As soon as a new threat is identified, all our customers are immediately immunized against it, protecting millions within minutes.

Why is antivirus software important?

Browsing the internet puts your privacy at risk. Companies want to track your behavior to create a detailed profile about you to serve personalized ads. Browser trackers enable companies to collect a significant amount of data and track your online activities. You can easily become a victim of adware, which is not only intrusive but also slows down your device.

The security of your devices is also at risk, especially when shopping online or using cloud-based services. Cybercriminals are on the lookout for personal data, trying to steal passwords, bank details, or even hijack your computer access to use your devices for attacks against others. Keyloggers, rootkits, spyware, Trojans, and worms are just some of the malware types that can attack your system.

To keep your system secure and protect your privacy, you need to install an antivirus software, designed to detect and remove malware. With regular virus scans, you can protect your computer against a wide range of threats.

Why is Windows Defender not enough to protect your system?

The Windows Defender Antivirus is installed by default on all devices running Windows 10. While it is a good option for conducting basic virus scans, it does not offer complete protection. When tested by IT security experts, the default windows antivirus didn’t perform as well as other antivirus software, often failing to block malware.

Furthermore, Windows Defender is not updated often enough to keep up with the new threats. To detect the new types of malware that are being spread daily, cybersecurity experts recommend an additional antivirus to conduct real-time virus scans and alert you as soon as a malicious threat is detected.
