PUP (Potentially Unwanted Program) also known as PUA (Potentially Unwanted Application) is the type of software that pretends to be a legitimate program, but in reality does nothing more than flood your computer with pesky pop-ups urging you to buy the program’s full version or download more adware. Some PUPs may also pretend to be legitimate browser extensions for Google Chrome, Mozilla Firefox, Safari or other browsers, whereas they may do significantly more harm than good by showing all types of ads on your browser and taking over your search engines.

PUP – How Did I Get It and What Does It Do?
The primary method via which such software tends to be distributed is bundling. This means that you could encounter these programs in the installers of other free programs, where they could be advertised in one of the installation steps as “free extra” or “optional offer”. These programs often aim to be spread through websites where they are advertised as an antivirus or some other Mac optimizing tool. An example for a PUP is Mac Auto Fixer – an extremely annoying fake optimizer that may show hoax detection with the main purpose to get you to buy its licensed version to fix all the “errors” detected by it.
Such programs may also come as other forms of software on your Mac, like browser extension, toolbars. They often tend to pretend to be useful, when in fact they may change your browser home page to a third-party one, which only aims to slither you third-party ads and collect information from your Mac via cookies. Such cookies and tracking technologies may obtain the following data from your system:
- Your browsing history.
- Bookmarked sites.
- Sites you have mostly visited.
- Online search history.
- Online clicks.
This data may be used to slither to you all forms of ads. If adware or a browser hijacker, this PUP may show the following advertised content on your Mac:
- Browser redirects.
- Push notifications.
- Highlighted text ads.
- Ad-supported search results.
Since some of those ads could eventually lead you to potentially unwanted or virus websites, this makes this software indirectly harmful for your computer and its removal is strongly advisable.
