Protect your PC against online threats
With the industry’s leading detection rates, Avira Free Antivirus protects you from viruses, worms, Trojans, ransomware, spyware, adware, and rootkits.
Top protection, performance, and usability on Windows 10
Avira's free antivirus provides complete virus protection and a variety of security, privacy, and performance tools. We combine artificial intelligence (AI), cloud technology, and our real-time virus scanner to keep your personal data safe from all types of malware, including Trojans, ransomware, spyware, and adware. Avira's mission has always been to protect people in the connected world. However, it's a sad fact that nowadays threats are not just caused by viruses and malware — making protection far more complex.
