Forget about
remembering passwords

Avira Password Manager creates unique, unhackable passwords for all your accounts, securely stores them, then automatically logs you in. And you can use it on all your devices.


Make your searches
safer and faster

Weary of your search engine tracking your queries? Avira SafeSearch is a browser extension that highlights infected sites in – and gives you faster access to – your search results.



Ransomware, a €1 billion industry, is growing 300% yearly. Our 2017 antivirus solutions identify, block, and remove ransomware before it takes your data hostage.


Evade global
surveillance with VPN

Avira Phantom VPN masks your IP address and encrypts your communications, evading snoops, confounding advertisers, and bypassing geo-restricted websites.


Get smarter with
Avira System Speedup

Our tune-up solution is vital intelligence: it wipes any traces of your online history, optimizes PC speed, and frees up drive space when you need it.


Security layers constantly
added to your Suite!

After upgrading, you’ll not only benefit from the latest additions to our 2017 portfolio, you’ll be the first to get new security components and services – for free – as soon as they launch.
