Structured Service App

Structured Service is a browser hijacker that will spam you with page redirects and ads and also alter the homepage, the search engine, the toolbar and some other elements of your browser. This is what Structured Service normally do and while on paper it might not seem like much, experiencing a hijacker first hand nearly always turns out to be a pretty unpleasant experiences.

The Structured Service Virus App will display pop up windows and messages

A browser hijacker is not a virus or some other dangerous program like a Ransomware or a Trojan but it could still be potentially hazardous (albeit not directly) and it is almost certainly not something that you’d enjoy having added to your Safari, Firefox, Opera, Chrome or to any other of the browsers that you might have. Here, we will show you how to take care of the so-called Structured Service “Virus” which is yet another recently released browser hijacker that many users have been complaining about as of late. But before we get to the part where we give you a detailed guide on how to remove Structured Service , we must first tell you something more about it.

Structured Service targets Mac

Nowadays, we use our browsers a lot and therefore we need them to be as fast and as optimized as possible. Though a hijacker app might actually sometimes promise you to help you with that, the reality is that it will usually do the exact opposite. The constant spam with ads and redirects to random sites and the changes to your browser’s components that you probably didn’t actually agree on are all things that most users find highly irritating and undesirable. The good news here is that you can, with proper, guidance, easily deal with this issue and remove the nagging software component from your browser. Just take a look at the uninstallation instructions down below and follow them in order to get rid of Structured Service .

What is Structured Service?

Due to the constant spam with all kinds of advertising materials and the usually low-quality of the newly imposed browser tools that a hijacker is likely to add to your browser, most security experts advise users to uninstall software like Structured Service, Formal Search or Bing Redirect from their machines or else, the computers might get exposed to different sorts of threats like Trojans, Rootkits, Ransomware and so on. Again, a hijacker, in and of itself, is usually not something malicious that is going to harm your computer. However, it’s ads may not be safe and sometimes it might redirect you to online addresses that aren’t overly reliable either. Besides, you certainly don’t fancy the endless irritation coming from the unstoppable barrage of commercials, banners and pop-ups showing on your screen which is usually more than enough of a reason for the majority of users to get rid of a browser hijacker. Just makes sure to only download quality software from now on and even then to always check for bundled components in the setup wizards since this file-bundling method is one of the most commonly used ways of getting a hijacker app installed onto more machines.

Detection Tool

Remove Structured Service Virus App


We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading ComboCleaner to see if it can detect parasite files for you.

The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively you can simultaneously press (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.



To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading ComboCleaner
a professional malware removal tool.
