Notification Booster Club is an ad-generating browser hijacker that affects Chrome, Firefox, and other browsers. Notification Booster Club could modify different aspects of the browser, and potentially cause security problems.

The Notification Booster Club Virus will make fake events on your calendar.

Due to its rather obscure and oftentimes unwelcome activities in the browser, this piece of software is regarded as a potentially unwanted one, and most experts advise the users to get it uninstalled from their systems before anything bad happens. We, too, advise you to remove this app from your computer, and browser, but know that there’s no need for panicking – you aren’t faced with some malicious computer threat, Notification Booster Club is not a real virus, or some Ransomware that can encrypt your files. The browser hijackers may add a new homepage to your browser in the place of the previous one, and they could also change the search engine, and spam you with page-redirects. Albeit annoying and unpleasant to have in the computer, however, those apps are typically not intended to cause harm. Any security issues that could come from them would typically be an indirect by-product of their activities, and not their actual goal. In most cases, a hijacker would mostly irritate you, and not do much else. After all, the main goal of such software is to promote stuff and boost the traffic to certain pages and sites. For example, by replacing your homepage with some promoted site, it makes sure that each time you start your browser, you’d be creating traffic to the site which is now your starting page. The new search engine is likely to present you with modified results that promote the sites and pages that the hijacker is intended to advertise.

  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.

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. 

Why and how could a hijacker be dangerous

Despite their overall harmless nature, these pieces of software could make your system less safe, which is why we told you that a hijacker may cause safety problems in the computer. One of the things that some hijackers do is they display intrusive ads all over the browser – the ads are present on each page, and tab, regardless of what web address is actually being visited at the moment. In most cases, the ads are not harmful, but the control over them is typically not overly strict. This significantly increases the possibility that some of them may originate from sketchy sites, and may redirect you to them if you click on the corresponding ad. Needless to say, this could land you on phishing pages, sites with shady content, and even on ones that spread Ransomware, Trojan infections, and other similar forms of malware. All in all, it’s best to not allow an intrusive app like Notification Booster Club to operate from within your browser. Besides, you’d hardly be gaining anything beneficial from the annoying program’s presence in your computer. Even if you like online shopping and are interested in exploring the ads, there are far safer ways to do this, which is why we advise you to take a look at the instructions below – they will help you remove the hijacker.
