n05.biz iPhone


n05.biz is a browser-hijacking program that is commonly bundled with other apps and installed on iPhones and iPads without being detected. Once inside the smart device, n05.biz tries to aggressively promote different types of web content via on-screen pop-ups, ads, banners and links that redirect users to random pages.

Rogue apps like this one are not as harmful as Trojan Horses, Ransomware or any other advanced malware, but if they ever enter your iPhone or iPad, you still may need to remove them.

The good news is that unlike most viruses that try to hide in the system, you will know that n05.biz or “Your iPhone is Not Protected” are there immediately: its never-ending shower of commercial messages and click prompts are common indications for the presence of this and other browser hijackers in the system.

As a matter of fact, such apps don’t harm the device directly, but they may be quite irritating and hard to ignore. Besides, the many ads that the hijackers spam you with might not be the safest thing to click on. Such random pop-up boxes and links may easily redirect you to dangerous web locations where real viruses are only waiting to infect your iPhone or iPad before you even realize it.

And the most annoying thing is that they tend to pop-up just as you’re ready to tap on something else, meaning that you might easily click on them by accident and land on some harmful, malware-filled website instead of the page that you want to visit.

Fortunately, this risk can be avoided if you act now and remove n05.biz along with all of its nagging message with the help of the instructions below.


Type Browser Hijacker

Remove n05.biz virus

If you have an iPhone virus, continue with the guide below.

If you have an Android virus, please use our Android Malware Removal guide.

If you have a Mac virus, please use our How to remove Ads on Mac guide.

If you have a Windows virus, please use our Windows Virus Removal guide.


First you need to close all pop-ups that are currently open.

  • If the pop-up has a checkbox named “Don’t show more alerts from this webpage” click on the checkbox before closing the Ad.
  • If a Block Alerts button happens to appear after you shut down a pop-up on your iPhone, iPad, or iPod touch tab that button to stop receiving alerts from the same page.

In case that a pop-up fails to close after performing the above operations:

  • On your Mac you should make your Safari browser close forcibly by pressing Command-Option-Esc. Select Safari from the list of Apps and force close it. After you force close it you need to restart Safari, but please hold the shift button while it starts. This will prevent any pesky Ads from opening automatically.
  • On your iPhone, iPad, or iPod touch you can do the same by pressing the home button twice in a quick succession. You’ll then see a preview of all apps that have been recently used. Swipe left to find Safari and then swipe up on the app’s preview to close it forcibly In order to prevent Safari from opening unwanted windows on startup go to Settings->Safari and Clear History, as well as Website Data. This will also clear your browser history and cookies so keep that in mind and export them if you want to keep them.

Choose Preferences from the Safari menu. Then do the following:

  1. Select the Security icon and then click on “Block pop-up windows“. This should stop many types of pop-ups from appearing.
  2. Next check on your homepage and the settings for the search engines. Adware likes messing with those. We can not provide more specific instructions for this, as you may be using many different browsers.
    • Select the General icon and look at the Homepage field. It should either be empty or filled with the address of the Homepage you want.
    • Follow up on the Search icon. Again it should be either the default search engine or any that you have set for yourself. Note that in some versions of Safari these settings are found in the General panel/

Open Safari and click on the Extensions button. Note that Adware use extensions almost exclusively to inject the pop-up Ads into your browser. Any extension on this list that you do not remember installing yourself is likely planted there by the Adware. Remove ALL extensions you are unfamiliar with.
