How to Remove a Virus from Your Phone - Android and iPhone Step by Step
updated 11 July 2026
Quick answer
On Android, boot your phone into safe mode to stop the suspicious app from running, revoke its device admin rights and uninstall it, then scan the phone with Google Play Protect. On an iPhone, real viruses are rare - it is usually calendar spam, an unknown configuration profile or scam pop-ups. You can remove all of that for free with built-in tools.
Step by step
- 1
Recognize the symptoms
Typical signs are full-screen ads popping up outside apps, new app icons you never installed, a sudden battery drain and browser redirects to strange sites. Think about when the problem started - often right after installing an app from outside Google Play or an APK file from the web. That app is usually the source.

Boot the phone into safe mode
In safe mode the phone loads only factory apps, so malware stops running and is easier to remove. On most Androids, hold the power button, then press and hold the Power off option until the phone offers to restart in safe mode. The path varies by model, so if you do not see it, check your phone's manual.
- 3
Revoke the suspicious app's admin rights
Malicious apps often block uninstallation by granting themselves device administrator rights. Go to Settings, open the Security section, find device admin apps and revoke the permission for the suspicious entry. Only then can you remove it normally.

Uninstall the malicious app
Press and hold the app icon and choose Uninstall, or do it in Settings under Apps. If you are not sure which one it is, sort the list by install date and look for anything unfamiliar from around the time the symptoms appeared. Remove every suspicious entry, not just one.

Run Google Play Protect
Go back to normal mode, open the Google Play store, tap your profile picture, choose Play Protect and start a scan. The tool checks installed apps and flags known threats. It is built in and free, so use it regularly.

Turn off browser notification spam
Some of these 'viruses' are actually notifications from sites you accidentally agreed to. In your browser, go to site settings and notifications, then revoke permission for sites you do not recognize. While you are at it, clear your browsing data to get rid of leftovers.

Factory reset as a last resort
If the symptoms persist, a factory reset removes all apps and data, returning the phone to its original state. Save your photos and contacts first, but do not restore apps from a suspicious source, because the problem will come back with them. After the reset, install apps only from the official store.
How to remove a virus from your phone for free
In most cases you do not need a paid antivirus. Safe mode, a permissions review and Google Play Protect are built-in, free tools that handle typical Android malware. Paid apps can help, but they are not necessary to remove a single malicious app.
Watch out for the opposite problem, though: some of the 'free antivirus' apps pushed in ads are threats themselves or flood the phone with ads. Install such programs only from known vendors and only from the official store, never from a link in a pop-up.
iPhone is a different story
Classic viruses are rare on the iPhone because apps run in isolated sandboxes. The problems people mistake for a virus are usually calendar spam (unknown events with links), scam sites warning about an infection, or a configuration profile added along with a shady app.
You remove calendar spam by deleting the subscribed calendar it comes from. An unknown profile sits in Settings under device management and VPN profiles - remove any you did not add. Finally, clear your browser history and website data, and the pop-ups will disappear.
Frequently asked questions
›How do I remove viruses from my phone if I do not know which app is to blame?
Boot the phone into safe mode and review the app list sorted by install date - look for unfamiliar entries from around the time the symptoms began. Also run Google Play Protect, which flags known threats. Delete everything suspicious.
›How can I remove a virus from my phone for free?
The built-in tools are enough: safe mode to stop the malicious app, a review of device admin permissions, and a Google Play Protect scan. All of them are free, so in a typical case you do not have to buy an antivirus.
›How do I enter safe mode on Android?
On most phones, hold the power button, and when the Power off option appears, press and hold it until the phone offers safe mode. The exact path depends on the model, so if that does not work, check your phone's manual.
›Can an iPhone get a virus?
Real viruses on an iPhone are rare. What looks like an infection is usually calendar spam, scam pop-ups or an unknown configuration profile. You remove them by deleting the suspicious calendar and profile and clearing your browser data.
›Will a factory reset definitely remove the virus?
A factory reset wipes apps and data, so it gets rid of the vast majority of malware. Just be careful when restoring a backup - if you restore an infected app, the problem returns. So reinstall your apps from scratch and only from the official store.
