In case that has taken over your iPhone or iPad, you should know that you’ve got yourself a browser hijacker. As scary as the term “browser hijacker” may initially seem, is nothing dangerous and won’t damage your Apple iOS device. However, there are some strong reasons to uninstall this app as soon as possible.

The Calendar virus will display pop up ads and messages

For instance, you may face some problems with your web browser (Safari, Chrome, Firefox, etc.) due to frequent redirects and the generation of unwanted popups, hard-to-remove banners, and aggressive advertisements all over the screen. It may start to crash, freeze or become unresponsive to your searches.

Also, you may notice some changes to the browser’s setup and preferences. Your favorite homepage and/or your search engine may be replaced with a new one. Additional toolbars and buttons may also be introduced to the affected web browser without your approval.

These modifications and the above-described browsing-related disturbance are typically enough for most web users to decide to remove or without a second taught.

Besides, keeping a browser hijacker like this one on your iOS may always increase the risk of being exposed to malicious links, fake web ads, and websites with harmful content. One wrong click may easily infect you with ransomware, Trojans, and other viruses which is simply not worth it.

With this in mind, it is best to get rid of as soon as possible. For your convenience, we’ve put together a step-by-step removal guide that will teach you how to do that without the need for expensive professional help.

  5. Lastly, click on Save to confirm the change.

Note that after you do that, you will no longer get any events automatically added to your Calendar. Instead, theyd go to the email you have provided. This also applies to the spam youve been getting – it would too go to your email, but at least you wont be getting the spam notifications on your screen.

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.

Here is one quick way to remove Calendar Virus from your iPhone:

  • First, on your iPhone/iPad, navigate to “Settings”.
  • Second, tap on “Passwords and Accounts”.
  • Then, navigate to Subscribed Calendars.
  • Once you get there, specifically look for anything that seems questionable, unfamiliar or suspicious.
  • If you detect anything, delete it.

If this doesn’t work, please proceed to the steps in the removal guide below.


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.
