Extra Window Mac “Virus” – How Did I Get It and What Does It Do?

Extra Window app is a very similar software to other unwanted and ad-supported applications we have discovered so far:

  • Coordinator Plus
  • WindowMix Mac App
  • These types of apps usually find their way on your Mac by being added from a third-party site, not the official Apple app store. They may be advertised as useful applications, but bear in mind that there is more to this than just them being legitimate.
