Why should you get extra protection?

The Microsoft Defender antivirus preinstalled on Windows laptops and PCs doesn't provide complete security online. Microsoft Defender is not able to detect all types of malware, especially new forms of ransomware and spyware, and updates are less frequent compared to specialized software.

More than just an antivirus

Avira Free Security is a powerful antivirus, capable of blocking new threats and zero-day exploits. The real-time virus scanner works seamlessly and efficiently, without slowing down your device. In addition to the top-rated antivirus, you get an entire suite of privacy and performance tools, from free VPN and password manager to automatic driver updates and memory optimizer.

Customers love us. Cyber attackers and privacy violators, not so much.
