Check if your iPhone is jailbroken or not. Jailbreak is a trick to remove many built-in limitations on iPhone, making it possible for the device to install unofficial apps. If you bought an iPhone from someone else, they may have jailbroken it to install malware. Here’s how to check if your device is jailbroken:
- Swipe down from the center of the home screen to open the search bar. [1] X Research Source
- Type cydia in the search bar.
- Tap the Search key on the keyboard.
- If the “Cydia” app appears in the search results, your iPhone is jailbroken. [2] X Research Source You can find out how to unjailbreak your iPhone yourself.

Watch out for pop-up ads in Safari. If you suddenly see a lot of pop-up ads (ads automatically appear on the screen), it is likely that the device has been infected with a virus. [3] X Research Sources
- Never click on a link in a pop-up ad. This can result in a more severe viral infection. [4] X Research Sources

Be wary of apps that quit unexpectedly. If the apps you use frequently quit unexpectedly, it’s possible that someone has found a vulnerability in that app.
- Update your iPhone apps regularly so you’re always using the most secure version. [5] X Research Sources

Look for strange apps. The Trojan is a malicious application that is difficult to recognize, so you will need to examine it a little more closely.
- Swipe through the home screens and folders to check for any strange or unremembered apps installed.
- If you see an app that looks familiar but you don’t remember installing, it could be a malicious app. It’s best to delete it if you don’t know what it is.
- To see a list of apps you’ve installed from the App Store , tap the Apps icon at the bottom of the store, tap your profile picture, then tap Purchased . [6] X Research Sources If there’s an app on your phone that’s not on this list (and isn’t from Apple), it’s probably a malicious app.

Check for unusual extra charges. Viruses often run in the background, using your data to connect to the Internet. Check your billing statement to make sure you’re not being taken advantage of in terms of data usage, or are suddenly paying for sending SMS messages to a premium claim number.

- You can learn how to test the battery yourself. You can also search which apps are using the most battery.
- If you see a strange application, remove it immediately.
Advice
- To make sure you’re getting the highest level of protection against viruses, make sure your iPhone is running the latest version of iOS.
- If you notice that your iPhone has been infected with a virus, it is best to restore it to its original factory settings.
