How To Check Your iPhone For Viruses & Malware?

One of the best-selling features of iPhones is their security measures. Compared to Android phones, iPhones are rarely infected with viruses and malware.

Often hackers use such malware to get access to your personal information, including financial data, and this could cause damage to you. It is advisable not to modify your phone through jailbreaking. Also, ensure that all your apps are downloaded from the Apple App Store only.

If you are looking for advice about iPhone viruses and malware, you are probably concerned about the possibility of an infection. How do you check your iPhone for viruses and malware?

Check Your iPhone for Viruses and Malware

1. Check Your Data Usage

Have you noticed that your data usage has increased more than in previous months? This could be due to a virus or malware on your iPhone.

Viruses and malware run in the background and use data to communicate with the internet. As a result, they use more data, and you will notice that your data usage is higher than in previous months.

Here is how to check your data usage:

  • Go to settings on your iPhone.
  • Select Cellular or mobile data, depending on your iOS version.
  • Check how much mobile data you have used in the current period. Is it higher than in previous periods?

Viruses and malware run in the background, which may go unnoticed for a long time. However, they use many of your phone’s resources, affecting your iPhone’s battery performance.

Thus, you may notice that your battery drains faster than usual. You may even find that your battery drains at a high rate even when not used.

Here is how to check which app is consuming a lot of power on your iPhone:

  • Go to settings on your app library, then select battery.
  • Scroll down, then select last 24 hours or last seven days to check battery performance. You will see a graph showing battery usage across hours or days. You will also see each app’s battery usage.

You have to check through all your installed apps to see if there is a strange app. To do this, swipe to your left from your home screen. Scroll to check all the apps on your device and delete the app that looks strange.

5. Check for Strange Pop-Ups

You may find that you are constantly getting pop-ups on your device. Too many invasive pop-ups could indicate malware or viruses on your iPhone.

6. Check Whether Your iPhone Is Jailbroken

The iPhone has built-in restrictions preventing installing unapproved apps. Some iPhones are jailbroken, and because of this, the inbuilt restriction is removed.

People jailbreak their iPhones mainly to install apps that are not on the App Store. As a result, you remove all restrictions that Apple implemented. As a result, you can customize your device, and at the same time, you risk the stability and security of your device.

Jailbreaking leaves your iPhone vulnerable to malicious apps. When you buy your iPhone from a reputable shop, it is probably not jailbroken. However, if you buy it from someone else, you must check to see if it is jailbroken.

Here is how to check

  • Open the search bar on your iPhone.
  • Type Cydia on the search bar.
  • If the app appears, then your phone is jailbroken.

You will have to reverse the process to protect your iPhone.

7. Check for Crashing Apps

It is very rare to find apps crashing on iPhones. Still, you may find that some do crash, but this is not an indication of malware or virus on your device.

However, if an app keeps crashing repeatedly, check to see if there is a new update, then install it. Here is how to do it:

  • Open App Store on your iPhone.
  • Then, click on your profile photo.
  • Check to see if any app needs updating, then update it. If there is more than one app, click on update all.

8. Check to See if Your iPhone Is Overheating

Overheating could be a sign that your iPhone has a virus or malware. This is because viruses and malware use many resources on your device.

But there are so many reasons why your iPhone is overheating. A faulty battery could also be the cause.

9. Run a Malware Scan

You can download antivirus software on your iPhone and scan for viruses or malware. Go to the App Store and search for an antivirus. There are many different types, and each works differently. Some have free versions, and others have paid versions.

Select one, download it, and install it on your device.
