GlobalEngineSearch is an adware. It will redirect you to pages. The app looks like a normal update for the Adobe Flash Player. However, a pop-up shows up making redirects and landing Mac users on different pages where they are presented with a notification. The notification states that they need to update their Flash player (which is not true).
Another situation that might occur is for your search engine to change and show different advertisements, generating revenue for its makers. While using its services, you can find yourself on unknown pages with many pop-ups and sponsored content coming from the files that the fake update has put on your machine. The threat might change the start page, new tab, and search settings for the browser applications you have on your Mac machine.
