Calevent is known for hijacking the browsers installed on Apple iPhones and other iOS devices. Therefore, Calevent falls into the software category of so-called browser hijackers.
This application has the capacity to integrate with your Chrome, Safari or other web browser. And as a result, it begins to impose its own settings and cause the browser to behave in certain ways. These types of programs are generally designed to earn revenue for their developers by means of displaying paid ads like popups and banners. And as other methods of promoting various products and services that they can profit from, programs like Calevent, Msgstars may also start triggering page redirects in your browser and even change its default search engine and/or homepage.
That goes to say that Calevent.online is merely considered a potentially unwanted program or PUP, though. Hence, it is not a virus and cannot harm your iPhone, iPad or iPod. But it can quite plausibly expose you to various unsafe web locations as a result of its aggressive online advertising practices. And that, in turn, has the danger of leading to infections with Trojan horse viruses, ransomware and other malware.
In order to protect yourself and your system from such things, we highly recommend refraining from tapping on any of the ads that come your way. There’s no telling where they may lead and it’s simply not worth the risk of compromising your device. Instead, the optimal course of action is to remove Calevent entirely. And we can help you with that in the removal guide you’ll find below.
|Danger Level||Medium (nowhere near threats like Ransomware, but still a security risk)|
|Symptoms||Popups, banners and other ads covering the screen during browsing sessions; changes made to the browser’s settings; page redirects, etc.|
|Distribution Method||Browser hijackers like Calevent are usually integrated in other apps in order for them to get distributed.|

This is the first thing you should try if you are getting targeted by this kind of spam.
- Log in yo your account at iCloud.com and tap on Calendar.
- Tap on the Settings icon (a gear icon) located in the lower-left corner of the screen.
- Now, select Preferences and then Advanced.
- Change the Invitations setting from In-app notifications to Email to and provide your current email.
- 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, they’d go to the email you have provided. This also applies to the spam you’ve been getting – it would too go to your email, but at least you won’t 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.
To remove Calevent.online 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 Calevent.online 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:
- Select the Security icon and then click on “Block pop-up windows“. This should stop many types of pop-ups from appearing.
- 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.
