How To Clear Calendar Virus Iphone

Many iPhone users have reported random events appearing in the Calendar app. You can remove the iPhone Calendar virus and secure the iOS device. We will address the root cause of the problem and provide information on how to prevent it from happening again. Do not panic and assume that the iOS device is hacked or compromised because it is a minor loophole that can be fixed in a couple of minutes. We will show you to prevent and lock down all doors for such loopholes in the iPhone/iPad.

Why do I keep getting Calendar virus on my iPhone and iPad?

There are two scenarios on why you keep getting the Calendar virus, and we will address both of them.

A. Third-party apps

Apple's Calendar doesn't auto-generate events in the app, and someone has to do it manually. If random appointments, events, and birthdays are showing up in the reminders, then you will assume that someone has hacked into the device. But, do not panic since it is a recognized scenario in the community, and it is happening due to certain aspects.

Many professionals iOS device owners subscribe to the third-party apps and integrate them with the Calendar. Those third-party apps are adding events in the Calendar app and unsubscribe from the service, and you are good to go.

B. Security Loophole

iPhone calendar spam is not a random security breach, and it occurs, when you have opened phishing emails. Almost all security solutions add email shields because they are aware of the invaders taking advantage of the loopholes.

Invaders plant malware in different elements such as text, web pages, emails, pop-up ads, and more. Email phishing is one of the common loopholes used to spam in the iOS system, where many users click on the attachments coming from an unknown sender. iOS device owners have to step up and protect themselves from such exploits.

All you have to do is to remove unknown Calendar integration from the iPhone, and I will show you how to do it in iOS 15.

Disable Calendar Access in iOS 15

Several email accounts are compromised in the past, and it could be the leading reason why spam events are showing up in the calendar app. Disallow calendar access in the iOS 15 and prevent any further reminders in the smartphone.

Tap on the Settings and choose Calendar.
Click on Accounts.

Tap on the account to access advanced options, and I chose Gmail.

Toggle "Calendars" to disable it.

Tap on "Delete from my iPhone/iPad" to confirm the action.

Now, it will remove every event added by the third-party app, and I'm not pointing finger at Google Mail and using it as a demonstration. If you find an unrecognized service that is using the Calendar app, then disable it.

Unsubscribe Third Party Calendar Service

You might have subscribed to a third-party service that is adding multiple elements in the Calendar app. Fortunately, you can remove it from the inbuilt app and get rid of all spam events once and for all.

Tap on the Settings > Calendar > Accounts.

Click on the third-party service account.

Tap on "Delete Account" to remove it.

Confirm the action by tapping on the "Delete from My iPhone" option.

That's it, you have successfully removed the account from the iOS device, and it won't continue adding new events in the smartphone. Repeat the same instructions, if you found multiple unknown or unrecognized accounts in the iOS 15 device.

Remove Spam Calendar Events in iOS 15

Now, clean up the house and remove remnants from the iPhone and let me show you the way. Of course, you have to spend a couple of minutes cleaning up the mess in the Apple app, but it's worth your time.

Open the Calendar app.
Tap on the "Calendar" option located at the bottom.

Tap on the event that is having a lot of spam elements.

Tap on "Delete Calendar" located at the bottom.

Confirm the action by tapping on "Delete Calendar" to remove it.

You have removed the event that has a lot of spam reminders. Repeat the same thing to remove multiple events from the Calendar app.

Enable Protective Functions in Browsers

Pop-up advertisements on many sites are designed to promote the products and services. However, I have come across a million pages in several years that have spread malware, adware, and different types of threats in the machine. I recommend the users block all sorts of pop-ups in mobile browsers. Safari is my go-to browser on the iPhone, or else, I prefer Firefox on PC.

Open the Settings > Safari.
Toggle to block pop-up ads and make sure the button is in green color.
Make sure to enable all four security options.
- Prevent Cross-Site Tracking.
- Hide IP Address.
- Fraudulent Website Warning.
- Privacy-Preserving Ad Measurement.

Enable all protection features in the browser and prevent any further problems later down the line. Remember, do not disable any feature in the list because it doesn't interrupt you from visiting sites or blocking web pages. In case, if this is not sufficient to protect the device, then you can switch to Firefox.

Enable Privacy Protection in Mail App

Apple Mail app has security protocols to prevent phishing, but you should ensure that they are enabled in the settings.

Open the "Settings" app.
Look for the "Mail" app from the list and open it.
Tap on "Privacy Protection" under "Messages" to continue.

Toggle to enable "Protect Mail Activity".

You have enabled email activity protection and let the Mail app scan for threats.

How to prevent iPhone Calendar Virus in future?

I'll start with iOS updates because Apple has addressed it in the past, and they have released patches from time to time to strengthen security.

Back up the saved data in the local storage or iCloud.
Charge the battery to 90%.
Switch to a high-speed Wi-Fi network.
Do not force shut down or force restart iPhone/iPad if you don't see the progress bar moving.

I'm asking the readers to create a local backup via iTunes if the Wi-Fi network has slower download /upload speeds and lower bandwidth. Remember, you have to create a backup and restore in the device later on, which is a testament to the internet connection.

Open the Settings and choose General.
Tap on Software Update > Download and Install.
Let the iOS device connect with Apple servers and fetch updated information.
Let the iOS device download the package from the Apple servers.
iPhone will prepare the update, so give it a few minutes.
Tap on "Install Now".
Your device will begin updating the software.

iPhone will reboot and land on the Apple logo with the progress bar on the screen. Let the iOS software take over the process and give it a maximum of twenty minutes to finish the update.
