Avira Free Antivirus is free of charge for home users, so it is available only for private, non-commercial use.
Unlike Avira Antivirus Pro, it does not include email protection (Mail Protection) or internet protection (Web Protection).
With Avira Web Protection you can browse with complete confidence because we block malicious websites, drive-by downloads, and hijack attempts on your web browser – not to mention phishing attacks via social networks and email.
Avira Mail Protection protects your unsecured, non-encrypted email traffic.
