Remove PrimaryRotator – Mac Adware

This potentially undesirable application (PUA) should therefore be dealt with by the user as soon as possible. The browser extension PrimaryRotator has been identified as being dangerous and capable of misbehaving with internet browsers like Safari, Google Chrome, and Mozilla Firefox. Since the PrimaryRotator app serves no purpose and merely irritates web users, there is no reason to permit it to run in the browser.

More about PrimaryRotator

It is clear from looking at the entry schemes of CharacterGeneration and ConnectSystem that PrimaryRotator is simply a rebranded version of the aforementioned dubious browser addon. All of these dangers come from a sizable adware gang, whose primary goal is to control the browser software and carry out various illegal actions like the ones listed below:

Search hijacking: The PrimaryRotator app was made to interfere with internet browser programs’ search functions. This malware will send online search requests made by Mac users to a predetermined server in order to extract certain data. The final search result on a reliable search engine like Google, Yahoo, or Bing is then displayed as a decoy.

Display advertising: Similar to other unwanted programs, PrimaryRotator has the ability to show a variety of advertisements on infected internet software. Every page and website a Mac user visits may have advertisements. As long as the malicious browser program is running, it may even pop up everywhere. It is clear that the developers of PrimaryRotator are making money online by taking advantage of the compromised browser.

Data tracking: PrimaryRotator injects specific internet cookies and codes, enabling it to monitor web users’ surfing habits. This type of adware is skilled at retrieving data from the browser’s storage and from online forms that consumers are filling out. This unlawful activity by PrimaryRotator may ultimately result in privacy theft.
