Remove AdminRotator – Mac Adware

AdminRotator is a dubious browser extension that targets Mac computers and specifically infects internet browser extensions like Safari, Google Chrome, and Mozilla Firefox. Because the primary objective of its operators is to use the infected computer as a tool in their revenue-generating plan, it was created to issue an excessive amount of advertising.

The AdminRotator program, like its forerunners SoftwareSkillMatrix and ProgramProcessor, is marketed as a browser plugin that improves online browsing and searches for Mac users. It promises to deliver precise, quick results that are useful for online users. AdminRotator, according to Mac security experts, is actually useless software that belongs to the threat class of potentially unwanted applications (PUA). It enters the Mac computer through the browser program, using a variety of intrusive tactics.

Effects of AdminRotator installation

The AdminRotator app starts making changes as soon as it successfully integrates with the internet program as a browser extension. It begins by altering the default search engine, which routes all user queries through predetermined servers. The goal is to gather data on a Mac user’s search activity, including search terms, user location or origin, and browser type and version. In addition to monitoring the online browsing activities of Mac users, the AdminRotator program is ready to show pop-up ads, redirections, and push alerts. The most bothersome thing about this advertising is that it frequently appears where it shouldn’t, such as in the page’s middle, where it obstructs users’ views. Mac users may see a warning indicating that “AdminRotator will damage your computer” if the browser program notices the adware’s improper conduct.
