Potentially Unwanted Applications (PUA) Shield

Potentially unwanted applications are applications that might be embedded within a legitimate software, to be installed along with the legitimate software. If you don't follow the installation wizard carefully, you might install these unwanted applications into your system, which can cause trouble to your system later. For instance, some unwanted applications might be designed to track your online behaviors and display various kinds of unwanted ads on your screen. By using this security software, you can protect your system from being infiltrated by unwanted software that is installed along with the installation of your legitimate software. The security system provided by Avira always warns you whenever a potentially unwanted application is about to be installed into your system.

Safe Browsing with Browser Tracking Blocker

Not only Avira Free Antivirus can protect your system from malicious threats, it can also protect you during your browsing activities. Whenever you are about to click a harmful link, the security system warns you about the harmful website page or file that you are going to access. Thus, you are fully protected from harmful websites that might be designed to steal your important information. The browser tracking blocker feature helps prevent websites from tracking your browsing behaviors so that they can display relevant ads to you.
