If you find apps on your iPhone that you don’t remember installing or experience app crashes or pop-ups out of nowhere, your iPhone could be infected with viruses.

While it’s highly unlikely for iOS devices to catch a virus, it’s still possible. So, how to check for viruses on your iPhone?

Let’s find out!

How to Check for Viruses on iPhone?

If you suspect that you have viruses on your iPhone, here are several ways that can help you to check.

Run an Antivirus Check

The easiest way to find out if your iPhone is infected with a virus is to run an antivirus software scan. If you haven’t downloaded one yet, a good security suite is an excellent investment to make, as you’ll be able to perform an iPhone virus scan at all times.

If you’re unsure which one to get, check out our top antivirus software picks for 2022.

Check for Unknown Apps

If you find apps that you can’t remember installing, it might be that a malicious app was installed on your phone without your awareness. Here’s how to detect these unknown apps:

  • Swipe through your home screen, and see whether you can spot apps that you don’t remember installing.
  • If you see one, make sure you delete it, as it’s probably a malicious one.
  • To check out every app you installed on the App Store, tap on the Apps Icon at the bottom of the store app, then tap on your profile photo, and then on Purchased.

Find Out if Your iPhone Is Jailbroken

If you have jailbroken your iPhone, know that you have voided your warranty plus potentially invited unwanted malware into your iPhone. Jailbreaking also removes any built-in Apple restrictions, making your iPhone even more susceptible to malware.

The best way to find out whether your iPhone has been jailbroken is to search for the app Cydia (which allows you to install apps not authorized by Apple) using the Search bar on your device. If Cydia appears in your search results, your phone has been jailbroken.

After all, most notable apps do not even require your iPhone to be jailbroken to install and use them, such as Cocospy, which is an excellent phone spying software.

Check for Unusual Cellular Data Activity

If a virus has contaminated your iPhone, it will use an excessive amount of your mobile data to transfer data from your phone. That’s why you need to check your cellular data usage and see if there’s a sudden rise.

Here’s how to check how much data you have used:

  • Go to Settings;
  • Tap on Mobile Network;
  • Finally, tap on Mobile Data.

Keep an Eye on Your Storage

Another way to check your iPhone for viruses is to look at your storage. Photos and videos will usually take up a lot of your device’s storage, but if you think that the remaining storage space is much smaller than usual, and yet the number of photos and videos is still the same, malware is the culprit.

To check your storage, go to Settings > General > iPhone Storage.

See if Your Phone Is Overheating

Although viruses can’t be noticed at first, they run in the background creating additional stress on the performance of your iPhone, which could lead to overheating.

Although there can be many reasons why your iPhone overheats, like a faulty battery, for example, it doesn’t exclude the possibility that a virus might be to blame.

Check if Your Battery Is Draining Faster

Your battery draining fast could be because of having many apps running in the background or the battery’s performance just gradually declining.

But, if you have a virus present in the background, that could also drain your battery faster.

What to Do if You Find a Virus on Your iPhone?

If you end up finding a virus by trying out some of the methods above or performing an iPhone malware scan, it’s important to act fast so that you can get rid of it before it does any further damage to your phone.

Below are a few methods you can try to remove a virus from your iPhone.

Restart/Force Restart

Restarting your iPhone is one way to get rid of the virus. To restart your iPhone:

  • Press and hold the power button until the slide to power off toggle appears on your screen;
  • Slide it to the right to turn the phone off;
  • To turn the device back on, press and hold the power button again.

If restarting your iPhone doesn’t work, try deleting your data completely by restoring it to factory settings, but make sure all your important data is backed up beforehand.

Delete Unfamiliar Apps

If you have spotted apps that you haven’t installed yourself, delete them. The process is quite straightforward — tap and hold the icon of the app, and then tap on Remove app.

Moreover, remove every app that’s not downloaded from the App Store, and don’t download apps from elsewhere. And more importantly, make sure to update your apps regularly, as app vulnerabilities can often increase the possibility of malware attacks.

Clear Your History

To protect yourself from viruses you might have picked up by clicking on a suspicious link or visiting a malicious website, clear your history. You can do so by going to Settings, then Safari, and scrolling down to Clear History and Website Data.

Use Antivirus Software

The antivirus software will prevent, detect, and clean a virus from your iPhone. It can do the “dirty” work for you and easily remove the virus from your iPhone.

There are many prominent antivirus software providers that can detect malware on an iPhone and effectively delete it.

Bottom Line

Viruses can be hard to detect because they run in the background silently. Luckily, there are a few ways to check for viruses on an iPhone, like running an antivirus check or checking for unusual apps or activities. So, worry not; getting rid of that virus shouldn’t be a hassle.


Can you get a virus from opening a text message?

It’s possible to get a virus from opening a text message, especially if you click on a malicious link that installs the app. Then the same message will be sent to other people on your phone.

Can an iPhone get a virus?

Although it’s very unlikely, iPhones can get viruses in cases when the phone is jailbroken, when clicking on links that lead to dodgy websites, or downloading non-App store apps.

How to know if your phone has viruses?

The signs to look out for when wondering how to check for viruses on iPhone are running out of storage, overheating, battery draining fast, a spike in mobile data usage, presence of unknown apps, and other unusual activities.
