WindowGroup Unwanted Extension – Spreading Techniques and Impact
WindowGroup is a suspicious browser extension that tends to affect commonly used web browsers installed on macOS. Similar to WindowMode, ExtraWindow, CoordinatorPlus and several other that seem to be from one and the same family, WindowGroup pretends to be a useful application that aims to improve your browsing experience. In reality, these apps primarily aim to hijack the settings of commonly used web browsers on Mac like Google Chrome, Safari, Firefox and Opera. Modifications of main browser preferences are usually applied without your knowledge or permission.
This impact could be explained by the fact that once WindowGroup has access to a target browser it becomes able to inject sponsored content during browsing sessions. The advertisements that may be displayed by this app may be of the following types:
You may have missed the moment when WindowGroup landed on your Mac because programs of this type are usually spread via shady techniques like software bundling, corrupted freeware installers, various torrent files and other. All these techniques aim to trick users into installing potentially unwanted programs without noticing the process.
So you might have installed the hijacker during the installation process of another supposedly useful app. Unfortunately, it is easy to agree with the installation of some extras without noticing their presence as the information about all app installers’ components is rarely disclosed properly. That’s why the Advanced/Custom configuration option is preferable. Sometimes it contains information about additional apps that will be installed by default if not unmarked. Eventually, there you will also find a tick box that prevents undesired apps from running on your Mac.
For the sake of your Mac security, it’s best to consider the complete removal of WindowGroup from the affected browser and system.
