Full features and system requirements

Don’t take our word for it, hear what the reviewers have to say about Avira.

"What I really like about Avira is the fact it runs completely silent without bothering you with all kinds of messages or something similar. On top of that, it is extremely light on your system resources. After I installed the application, I entered in task manager and I was surprised to see that there were no significant modifications in the CPU usage and Memory fields."

"Avira found and disarmed all of the rootkits and other malware infections tossed at it. Avira's program was not just the most thorough tool of the group, but also the fastest. It led in speed tests for both on-demand scans (which you schedule or start manually) and on-access scans (which happen automatically during tasks such as copying files)."

You don’t need much! Just a PC running Windows 7 (32-bit or 64-bit) or higher, or a Mac running OSX 10.10 (Yosemite) or higher, 1024 MB+ of RAM, and 800 MB+ of hard disk space. That’s it!
