More about adware

Pretty often, adware can operate as a browser hijacker. It can promote a fake search engine by changing the web browser's settings. Usually, browser-hijacking apps do not allow to undo their changes while they are present. More adware examples are ComputingInteractive, SmartProducts, HorizonLiving.

How did ColossusAspect install on my computer?

Usually, adware gets downloaded and installed unintentionally. It is caused by clicking deceptive advertisements, using fake installers. Also, adware often is distributed using downloaders and installers for other software. Advertisements can download or install adware when designed to run certain scripts.

Downloaders/installers used to distribute adware have "Advanced", "Custom", or other settings (or ticked checkboxes). Unwanted downloads/installations are caused after downloading or installing software without changing the aforementioned settings (deselecting unwanted apps).

How to avoid installation of unwanted applications?

Download applications (and files) from legitimate sources (official pages, platforms). Do not trust downloads from third-party downloaders, unofficial pages, P2P networks, and similar sources. Also, do not click on advertisements displayed by questionable pages or allow those pages to show notifications.

Examine downloaders and installers before finishing download and installations. Check them for unwanted applications and deselect those apps. If your computer is already infected with ColossusAspect, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
