You are not the only one dealing with this issue. Several Mac users have reported having trouble removing permanently a couple of pop-ups known as “ExtraBrowser” and “CentralStructured“. Note that these two pop-ups may be coming from different adware applications which have been bundled in one installer. You could be witnessing either one of them, or both of them simultaneously.
You may be seeing a white screen showing up on the desktop, first saying that it is loading and then that the installation is complete. It appears that all these issues are stemming from adware applications which may have sneaked into your system.

CentralStructured Pop-Up – Why Do I Keep Seeing it?
The CentralStructured pop-up may be related to an adware application or a bogus search engine known as AuraSearch (aura-search.net). If your browser’s homepage and new tab page is changed to aura-search.net without your consent, then you are dealing with a browser hijacker.
You should keep in mind that AuraSearch could be bundled with a variety of potentially unwanted applications (or PUAs) with browser-hijacking capabilities, so unless you do a thorough search on your Mac or scan it with an anti-malware program, you cannot be certain what caused it. The CentralStructured pop-up you’re seeing in your browser is most likely related to the same PUA/adware.
You may have missed the moment when the PUA causing the CentralStructured pop-up landed on your Mac because PUAs are usually delivered via shady techniques such as software bundling, corrupted freeware installers, various torrent files and other. All these techniques aim to trick users into installing unwanted programs without noticing the installation process.
In a nutshell, you might have installed a potentially unwanted application while you were installing another supposedly useful app (a method shortly known as bundling). Unfortunately, it is easy to agree with the installation of some extra apps without noticing their presence because the information about added extras is rarely disclosed in a proper manner.
There is also the possibility of a drive-by download. If you don’t recall downloading any app, be it legitimate ot suspicious, you may havе visited an infected website. Note that even legitimate websites can get infected. Long story short, the infected website could leverage a vulnerability in your web browser to carry out a drive-by download. Once the adware/PUA is installed, it may start performing a list of illicit actions, such as collecting your information, redirecting you to malicious websites, and generating lots of intrusive advertisements on all the pages you visit.
For the sake of your device’s security, it’s best to consider the complete removal of OutputData “virus” from the affected browser and system.
