ExtraList

ExtraList is an application for the Mac OS that may be advertised as a search-enhancing tool that is meant to help users find better results online. However, users who opt to install the ExtraList program may soon be disappointed by what it has to offer – this application is categorized as a Potentially Unwanted Program (PUP) by many security products. While it does not cause harm to your system, it may impair your browser's functionality by tampering with the settings and configuring your browser to use a different new tab page or search engine.

It is possible that using the websites that the ExtraList PUP promotes may expose you to advertisements and marketing offers that you may not be interested in. Overall, the purpose of ExtraList seems to be different from the one advertised entirely – instead of helping you, it is meant to promote its own offers and affiliate links that are meant to generate profits for ExtraList's developers.

While PUPs like this one are not a major issue, their removal is strongly recommended. Although you can complete this task manually, it is much better to do it with the assistance of a trustworthy Mac security product
