Adware in general
In most cases, adware is designed to display annoying (intrusive) advertisements. In certain cases, it can change the settings of a web browser (hijack a browser) and collect various data. Either way, it is highly advisable not to have any adware installed on a browser or the operating system.
More adware examples are VastVista, IntegerLocator, and AdvancedControl.
How did MajorSector install on my computer?
Adware is often distributed via fake Adobe Flash Player installers, deceptive advertisements designed to run certain scripts, and installers for other software. When software is bundled with adware, its installer has "Advanced", "Custom", or similar settings. Adware gets installed after completing software installation without changing those settings.
How to avoid installation of unwanted applications?
Do not use shady websites to download software updates (or the software itself). Download applications from legitimate sources (official pages and platforms). Do not trust notifications and advertisements displayed by questionable pages.
Check downloaders and installers for optional downloads and installations and deselect them before downloading or installing software. If your computer is already infected with MajorSector, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
