iPhone is a potentially unwanted program that is mounted on iOS devices such as iPhones and iPads and is used to reroute users to pages that actively promote various products, services, and other sites. Though not malicious on its own, may expose your smart device to damaging threats including Trojans and Spyware, so it should best be uninstalled.

The Virus will display pop up ads and messages


The symptoms of having Iosdfnc are typically hard to ignore. They usually include dozens of banner ads that tend to suddenly pop-up (Clear Your iPhone From Malicious Attacks) on the screen when using your iPhone or iPad and a number of unwanted and unauthorized modifications to your browser such as a new homepage, a new search engine, and some third-party tools and toolbars.

Whether you are using Chrome, Firefox, Safari, or the default “Internet” browser on your device, such unauthorized changes will ultimately affect your overall web browsing experience and the use of your iOS device. What is more, any unauthorized changes to your web browser preferences, combined with the constant generation of random ads and auto-redirects may expose you to all kinds of deceptive, misleading, or sketchy web materials that may infect your iPhone with viruses and other malware. That being said, it is important to uninstall as soon as possible and the removal guide below can show you how to do that in a quick and safe manner, if you have a few minutes to spare.

As far as prevention is involved, the key to keep and similar potentially unwanted apps away is to always check user feedback on programs that you intend to install and if possible avoid downloading anything out of the Apple App Store.

Remove Virus from iPhone

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.
  1. 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.
