Trojans, viruses, spyware… Not with our free malware removal software

Avira Free Security is a powerful malware removal software that includes a wide range of tools for security, privacy, and performance.

What is malware?

Malware is shorthand for malicious software that infects your system. It’s developed by cyber-attackers in order to steal personal data, gain access to your device, or cause damage to it. Rootkits, viruses, trojans, spyware, adware, worms, and browser-hijacks are all malware.

Malware is typically spread through email attachments, phishing websites, malicious advertisments, malicious software disguised as utility software, and even GIFs or text messages.


Trojans sneak into your system, often disguised as a legitimate tool.


Spyware monitors what you do online and collects data.


Ransomware encrypts the infected system, locking the user out until they pay a ransom.


Keyloggers log all your keystrokes and give cyber-criminals your login credentials.


Viruses can infect the operating system and slow it down or stop it from loading altogether.
