PrimaryIndexer

PrimaryIndexer is a Mac utility that may pose as a search-enhancing feature, but its true mission is to bring undesired changes to your Web browser's configuration. PrimaryIndexer is capable of acting as adware – this means that it will inject advertisements in your Web browser, and may often end up promoting content that is not reliable. In addition to injecting advertisements, PrimaryIndexer also may modify your browser's settings, so that you will be redirected to a 3rd-party website whenever you try to search the Web. Needless to say, such intrusive behavior should not be tolerated, and the removal of PrimaryIndexer should be your top priority.

Users often may be unaware that PrimaryIndexer is present on their Mac computers because this software does not have a dedicated installer or download location – it often is installed by using misleading instructions, promises or fake downloads.

If your Mac or Web browser appears to be acting strangely, then the best thing to do is to run a reputable anti-malware scanner, which can check your computer for any troublemaking applications like PrimaryIndexer.
