Remove MapperTrack
MapperTrack is a Mac application that antivirus products identify as a Potentially Unwanted Program (PUP.) This software has no valuable or redeemable features. Users often end up installing it accidentally, because of interactions with fake content or software bundles. Once a user installs MapperTrack, the app may silently insert a new Launch Agent that allows it to run whenever the system boots up.
MapperTrack works in the background and aims to manipulate the settings of Web browsers like Safari, Chrome, or Firefox. It does this in order to promote 3rd-party sites. These might show up in your browser when you try to search the Web or to load a new tab. While this is not harmful, it will certainly have a negative impact on your Web browsing experience.
Users who notice MapperTrack and try to remove it manually might not succeed. This PUP will keep on working in the background even if it does not show up in the list of installed applications. The proper ways to deal with intrusive Windows or Mac apps is to remove them via antivirus software. Even though Macs tend to be pretty secure, using 3rd-party anti-malware services is still strongly recommended. They will fend off not just intruders like MapperTrack, but also high-profile Mac malware.
