Notice Cleaner

Notice Cleaner is an iOS app that is labeled as potentially unwanted because it forces the user’s browser to automatically open different unknown sites and it changes the browser homepage and search engine. Notice Cleaner can be described as an iPhone browser hijacker that needs to be removed in order to keep the device safe.

The Notice Cleaner iPhone Calendar Spam

There are lots of different issues that can arise as a result of the presence of such an app on an iPhone device. One of the main problems here is the sheer number of permissions that these apps tend to obtain once they get installed. With so many system permissions, a hijacker like Notice Cleaner could make changes in the system and browser settings, keep tabs on your browsing activity, generate ads and page redirects without permission, and return information about your device to its creators who could, in turn, use this data in different ways, without requiring your approval.

One of the worst things about all this is the fact that, a lot of times, the content that unwanted apps like Notice Cleaner and Notifguide advertise is not particularly safe or reliable. Many of the pop-ups, banners, and box messages this app puts on your screen and in your Safari or Chrome browser may actually be linked to dangerous and unsafe sites. In some instances, you may even get your iPhone attacked by different types of viruses including ones like ransomware and Trojans after a browser hijacker redirects you to some potentially dangerous website.

Needless to say, the only wise course of action if you have a hijacker on your device would be to delete the intrusive app. You could do that by following the steps from our removal guide that’s available below – something we strongly advise you to do right away in order to keep your device safe from potential virus attacks.


Name Notice Cleaner
Type Browser Hijacker
Danger Level Medium (nowhere near threats like Ransomware, but still a security risk)
Symptoms Possible symptoms are the generation of obstructive pop-up ads on your screen and the sudden redirection of your Safari browser to unfamiliar sites.

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.
