If you’ve tried out all the above and still suspect that your device has malware—or you explicitly find malware your iPhone—taking immediate action is vital. Here are some of the easiest ways to get rid of a virus on your device.
Restarting your iPhone can, in some cases, get rid of malware.
How you’ll do this depends on the device you have. For instance, if your iPhone has a home button, hold this and the on/off button. Do so until your phone turns off and back on again.
If your iPhone doesn’t have a home button, you can still force restart your iPhone and put it into Recovery Mode.
If restarting your iPhone doesn’t work, try restoring to factory settings instead. This will delete your data, however, so make sure you have a back-up somewhere (and that the malicious app isn't reinstalled when you reinstall the back-up).
If you notice apps that shouldn’t be on your phone, deleting them should help to rid your phone of malware. To do this, you can hold on to its icon until the individual app is highlighted then click Remove App.
You might also want to remove anything you didn’t download from the App Store. Going forward, you should refrain from downloading non-App Store apps.

To clear your history, go to Settings > Safari. Then, scroll down to Clear History and Website Data.2 Images ExpandExpand

Even if you haven't invested yet, downloading a decent security suite is very much worthwhile, and it can still scan for viruses.
If you’ve tried all you can to rid your iPhone of malware, you might need to replace your device.
Since most cases of malware are user-made and involve acts like jailbreaking, you might find that Apple’s warranty doesn’t cover your issue.
