Notification-fix1.best infects most popular web browsers found on iOS devices, such as Chrome and Safari. Notification-fix1.best is an application that falls into the class of programs known as browser hijackers.


The Notification-fix1.best Virus will fill your calendar with messages and ads.

If this application has been found on your iPhone, iPad or iPod, then you have likely come to know about it after noticing certain changes in your favorite browsing program. For instance, you may have noticed a new homepage and/or the default search engine may have been replaced with a new one without you even being asked. In addition, there may have been a new toolbar added to the browser, as well as perhaps some other browser elements.

This rather invasive activity usually surprises users and even scares many of them into thinking that their device has been infected by some terrible virus. However, browser hijackers are not dangerous in that way and don’t aim to harm your system. But the developers of such applications rarely care much for the safety of the websites that they promote. And so it’s very possible that you may at some point be exposed to some unsecure web location and through that to viruses and malware like Trojans, spyware and ransomware.

For this reason we generally don’t recommend allowing software like this to stick around for very long. And instead, it’s best to see to its prompt removal as soon as it’s been discovered. We even have a step-by-step removal guide prepared to help you deal with Notification-fix1.best accordingly. And once you’ve removed the hijacker, you will also be able to restore your original browser configurations.

Detection Tool [Guide_iOS]

To remove 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 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.
