Download Avira Free Antivirus

Protect your identity, banking information, and privacy.

Cybercriminals want your credit card details, passwords, and other personal information – and use malicious software like rootkits, keyloggers and spyware to get them. Our virus cleaner blocks all of them. The virus cleaner also protects from DNS-hijacking, blocks botnets and banking Trojans. A key feature is the virus protection that keeps you safe from ransomware that locks your personal data and prevents access to your photos and videos.
