The next part of this post will tell you how to check your iPhone for an actual Calendar spam virus and how to deal with such a virus if it gets detected.

To remove Notification-cleaner1.best Calendar Virus quickly you can try this:

1. Go to Settings on your iPhone/iPad.
2. Open Passwords and Accounts.
3. Then go to Subscribed Calendars.
4. Look for Notification-cleaner1.best or anything that looks suspicious and delete it.


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.
