The “Custom Internet” Virus

"Custom Internet" Virus

User complaints from the “Custom Internet” Virus.

Apps like “Custom Internet”, Structured Service and Results Value are seen as unwanted on any computer but, unfortunately, this is one of the most common types of potentially unwanted applications and the chances of landing one such app yourself are especially high if you regularly download free software or install apps from different torrents, free download platforms and ads. In fact, if you are on this page, then you probably already have this browser hijacker inside your browser and are now looking forward to removing it, stopping its ads and page-redirects and reverting its homepage, toolbar or search engine changes that it has made. “Custom Internet” is one of the newest representatives of this class of software but we won’t get surprised if you have mistaken it for some sort of a nasty Trojan Horse or Ransomware infection. This is a common confusion among the users who detect this application inside their Chrome, Firefox, Explorer, Edge or another browser and notice the unwanted changes that it has automatically imposed. “Custom Internet” may replace the main homepage or the default search engine with some sponsored ones as well as install some new browser buttons and toolbars. In addition to that, it may start to display different pop-up windows, new tabs that redirect you to sponsored pages as well as banners and ads that are typically hard to remove and that may cover most of your screen. What is particularly annoying is that, no matter what you do and how you try to uninstall the browser changes or remove the pop-up ads, they simply seem to stick to the browser and and not go away. Even changing the default browser with another one may not save you from the ads generated by “Custom Internet” because the application can integrate with any browsing program that you install. Then how can you deal with this browser hijacker in a fast and effective way? This is what we explain in the removal guide below.

“Custom Internet” is on Mac

In order to answer this question, we first should make it clear that the browser hijackers are applications similar to adware and they serve the interests of the online marketing industry. To be more specific, they are the result of the agreement between their developers and the manufacturers and distributors of different goods and services. The latter, of course, benefit from promoting their products, services and websites directly on the users’ screen. But the developers of this type of software are just as interested in this as the manufacturers because they earn money by displaying sponsored ads and links that redirect the users to the desired pages and by making the users click on specific promotional messages. This most often happens thanks to reward systems such as Pay Per Click. But these same revenue accumulation models sometimes encourage the use of somewhat invasive advertising tactics from the developers of applications like “Custom Internet”. In their attempts to earn more, they tend to overdo it with the amount of sponsored commercials they display through their software and this causes irritation and disturbance to the users. In addition, some people fear the random applicationects and the sketchy pop-ups as it is known that these can often be used as transmitters of Ransomware, Trojans and other nasty viruses. Thus, most users prefer to uninstall the ad-generating software as soon as possible.

“Custom Internet” Mac Virus Removal


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.

First, Force Quit Safari again.

Now if you are using a Wi-Fi connection turn it off by selecting Wi-Fi off in you Mac’s Menu. If you are using a cable internet (Ethernet connection), disconnect the Ethernet cable.


Re-Launch Safari but don’t forget to press and hold the Shift button while doing it, so no previous pages can be opened up. Now, Click on Preferences in the Safari menu,

and then again on the Extensions tab,

The threat has likely infected all of your browsers. The instructions below need to be applied for all browsers you are using.

Again select Preferences in the Safari Menu, but this time click on the Privacy tab,
