More about adware

Pretty often, adware can access and collect various information (for example, browsing-related data and even sensitive information such as passwords, credit card details). Either way, adware is software that should never be installed on the operating system. More examples of adware-type apps are AllianceInstallations, ImmersiveTask, EffectiveVision.

How did CheckFeature install on my computer?

In many cases, adware is distributed using deceptive websites and fake installers. Those websites use scare tactics or other deceptive methods to trick users into downloading and installing adware. Also, users download and install adware by clicking on shady advertisements or through downloaders or installers for other programs.

Downloaders and installers used to distribute adware (or other unwanted apps) have "Advanced", "Custom", or similar settings. Users download or install adware alongside other software when they finish downloads or installations without changing the aforementioned settings.

How to avoid installation of potentially unwanted applications?

Download files and programs from official websites and use direct download links. Avoid using unofficial pages, third-party downloaders, P2P networks, and similar sources as tools for downloading anything. Do not click on advertisements that torrent sites, adult dating pages, and similar sites have on them.

Deselect unwanted apps before downloading and installing software. If your computer is already infected with CheckFeature, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
