Many iPhone users are reporting random events appearing in the Calendar app. You can remove iPhone Calendar virus and protect your iOS device. We will fix the root cause of the problem and provide information on how to prevent it from happening again. Don't panic and assume that the iOS device is jailbroken or compromised because it's a minor loophole that can be fixed in a couple of minutes. We will show you how to prevent and block all doors for such loopholes in iPhone/iPad.
Why do I keep getting the Calendar virus on my iPhone and iPad?
There are two scenarios for why you keep getting the Calendar virus, and we'll cover both of them.
A. Third Party Applications
Apple Calendar doesn't automatically create events in the app, and someone has to do it manually. If random appointments, events, and birthdays appear in reminders, you assume someone has hacked your device. But don't panic as this is a recognized scenario in the community and it happens due to certain aspects.
Many professional iOS device owners subscribe to third-party apps and integrate them with the calendar. These third party apps add events to the Calendar app and unsubscribe from the service and you're done.
B. Security Loophole
iPhone calendar spam is not an accidental security breach and it occurs when you open phishing emails. Nearly all security solutions add email shields because they know attackers are exploiting loopholes to their advantage.
Attackers inject malware into various elements such as text, web pages, emails, pop-up ads, and more. Email phishing is one of the common backdoors used to spam the iOS system when many users click on attachments that come from an unknown sender. iOS device owners need to step up and protect themselves from such exploits.
All you have to do is remove the unknown iPhone calendar integration and I'll show you how to do it in iOS 15.
Disable Calendar Access in iOS 15
Several email accounts have been compromised in the past and this may be the main reason spam events are shown in the calendar app. Prevent access to the calendar in iOS 15 and prevent further reminders on the smartphone.
- Press Settings and choose The calendar.
- Press Accounts.
- Click on an account to access more options and I chose Gmail.
- Toggle”Calendars‘ to turn it off.
- Click on “Delete from my iPhone/iPad‘ to confirm the action.
It will now remove every event added by a third party app and I am not pointing my finger at Google Mail and using it as a demo. If you find an unidentified service using the Calendar app, disable it.
Cancel a subscription to a third-party calendar service
You may have subscribed to a third party service that adds multiple items to the Calendar app. Luckily, you can remove it from the built-in app and get rid of all spam events once and for all.
- Press Settings > The calendar > Accounts.
- Click on Third Party Service Account.
- Click on “Delete account” to remove it.
- Confirm the action by clicking on the “Delete from my iPhone” option.
That's it, you have successfully deleted your account from your iOS device, and it will no longer add new events to your smartphone. Repeat the same instructions if you find multiple unknown or unrecognized accounts on your iOS 15 device.
Remove Spam Calendar Events in iOS 15
Now tidy up the house and remove the leftovers from the iPhone, and let me show you the way. Sure, you'll have to spend a couple of minutes tidying up the Apple app, but it's well worth your time.
- Open the Calendar app.
- Press “The calendar“located at the bottom.
- Click on an event that has a lot of spam items.
- Click on “Delete calendar” is located at the bottom.
- Confirm the action by clicking on “Delete calendar” to remove it.
You deleted an event with a lot of spam reminders. Repeat the same to remove multiple events from the Calendar app.
Enable security features in browsers
Pop-up ads on many websites are designed to promote products and services. However, over the years, I came across a million pages that were spreading malware, adware, and various types of threats on the machine. I recommend that users block all kinds of pop-ups in mobile browsers. Safari is my favorite browser on iPhone, or I prefer Firefox on PC.
- Open Settings > Safari.
- Toggle to block popup ads and make sure the button is green.
- Be sure to enable all four security settings.
- Prevention of cross-site tracking.
- Hide IP address.
- Fraudulent site warning.
- Measuring ads while maintaining privacy.
Turn on all security features in your browser and prevent further problems in the future. Remember, don't disable any of the features in the list because they don't prevent you from visiting sites or blocking web pages. In case this is not enough to protect your device, you can switch to Firefox.
Enable privacy protection in the mail app
The Apple Mail app has security protocols to prevent phishing, but you need to make sure they're turned on in the settings.
- Open”Settings” Appendix.
- Search for “mail” from the list and open it.
- Click on “Privacy Protection” under “Messages” continue.
- Toggle to enable “Mail activity protection“.
You turned on email activity protection and allowed the Mail app to scan for threats.
How to prevent iPhone Calendar Virus in the future?
I'll start with iOS updates because Apple has addressed this in the past and released security fixes from time to time.
- Back up your saved data to local storage or iCloud.
- Charge the battery up to 90%.
- Switch to a high-speed Wi-Fi network.
- Do not force shutdown or restart your iPhone/iPad if the progress bar is not moving.
I ask readers to create a local backup via iTunes if the Wi-Fi network has slower download/upload speeds and less bandwidth. Keep in mind that you must back up and restore it to your device later, which is an indication that you have an internet connection.
- Open Settings and choose General.
- Click on Software update > Download and install.
- Allow your iOS device to connect to Apple servers and get updated information.
- Let the iOS device download the package from the Apple servers.
- The iPhone will prepare the update, so please wait a few minutes.
- Click on “Install now“.
- Your device will start updating the software.
The iPhone will reboot and land on the Apple logo with a progress bar on the screen. Let the iOS software take over the process and give it a maximum of twenty minutes to complete the update.
I have shown you several ways to remove iPhone calendar virus from the latest iOS 15 and it is also applicable to iOS 14. It is extremely important to update the software to the latest version as it comes with security patches and privacy intrusion prevention tools.
