Short on time? Here’s how to remove viruses & malware from smartphones in 2024:

  • 1. Install an Antivirus & Run a Scan — Download a trustworthy antivirus program like Norton and run a full scan.
  • 2. Remove Viruses & Malware — When the scan has finished, go through every detected file and remove any threats.
  • 3. Stay Protected — Use a trustworthy and reliable internet security package to protect your device from future threats. I particularly like Norton, which had 100% malware detection rates in my tests. It also has excellent additional features, including web protection, Wi-Fi security alerts, an app advisor, SMS spam filters, a password manager, and more. Norton also includes a 14-day free trial on mobile and a 60-day money-back guarantee, so you can try it out before making a purchase.

Removing viruses and malware from your smartphone is easy. However, the steps differ slightly depending on whether you’re using Android or iOS.

If you’ve downloaded malware onto your Android device, you need to get a mobile antivirus app (such as Norton) and run a full system scan to remove it. But if you’re using iOS, you don’t need to worry about malware.

That said, having an antivirus app on your iOS device is still important — especially if it’s jailbroken. While iOS has a reputation for being more secure compared to other operating systems, you still need to protect it from threats such as data theft, phishing websites, and smishing attacks. You also need to maintain good security when using public Wi-Fi networks.

This guide will show you how to protect your device and restore it if it’s been compromised by malware. It’ll also offer you some extra smartphone security tips that you need to know in 2024.


What Kinds of Malware Affect Mobile Devices?

Note: If you just want to remove malware, you can skip straight to our removal guide.

Several types of malware can affect your mobile device. They most often get onto your device when you’ve downloaded malicious apps or visited untrustworthy websites. Phone malware can include:

  • Viruses — Delete your data, steal your information, and make purchases without your permission.
  • Ransomware — Locks your device until you pay a ransom.
  • Spyware — Monitors your data usage and sends it to fraudsters so that they can steal your online accounts and identity.
  • Botnets — Uses your mobile to send fraudulent emails and launch cyberattacks against others.
  • Rootkits — Gives hackers remote access to your device so they can steal personal data or modify your operating system.
  • Adware — Generates revenue for hackers by constantly displaying unwanted advertisements on your device.
  • Potentially unwanted applications (PUAs) — Can steal your data and spread other forms of malware.

You can also have your personal data stolen after visiting phishing websites. That’s why it’s super important to install an antivirus like Norton, which comes with web protection that can stop you from accessing dangerous sites.

How to Remove Malware & Prevent Security Issues on Your Smartphone (Step-By-Step Guide)

If you think your phone has been infected with malware, follow the 3 steps below to remove threats and stay safe going forward. The simplest way to get rid of malware and prevent future security issues on your smartphone is to download antivirus software like Norton. Once you’ve downloaded Norton, run a full system scan, remove all malware, and keep it installed on your device so you can stay protected from future threats.

But even with an antivirus running, you should still be cautious when using the internet. Don’t tap on links you don’t recognize, don’t download apps from outside the Google Play or Apple App stores, and don’t give your details to people you don’t trust.

Step 1. Install a Mobile Antivirus App and Identify Any Malware or Cybersecurity Threats

Download and install a trustworthy antivirus app. Norton is my favorite for mobile because it comes with several excellent features:

  • Malware scanner (Android only) — Scans your Android device for malware threats and quarantines any it finds.
  • Web protection — Stops you from accessing malicious websites that steal your data and personal information.
  • App Advisor (Android only) — Alerts you to dangerous apps before you download them.
  • Virtual private network (VPN) — Protects your privacy online by hiding your IP address behind a virtual one.
  • Password manager (separate app) — Uses 256-bit AES encryption to store your passwords in an unbreakable vault, so hackers can’t steal them and you never have to remember them.
  • And more…

If you’re an Android user, run a full scan of your device once you’ve installed an antivirus app. It’s really important that you let the scan run to completion, as this will ensure that any malicious apps or files are quarantined. Once your antivirus has redirected you to your infected file list, you can proceed to step 2.

If you’re an iOS user, you can skip straight to step 3 since your iOS device isn’t at risk of malware. Apple launches all third-party apps in a sandbox mode, so even if a malicious app did get onto your iOS device, it wouldn’t be able to cause any damage.

Step 2. Remove Any Malware and Fix Other Security Issues

Your antivirus will have quarantined any suspicious files on your device after finishing the full system scan. These suspicious files are moved to a secure quarantine folder where you can review them before you delete them. Go through your antivirus’s quarantine folder before making any deletions because sometimes antiviruses quarantine false positives — flagged files that aren’t actually malware.

If you’re an advanced user, you’ll recognize false positives. However, if you’re less tech-savvy, check with your antivirus provider’s customer support team if there are any files in quarantine that you’re not sure about deleting.

Either way, restart your phone and rerun the full system scan once you’ve removed all the malware from your Android device. Keep repeating this process until you can scan your device without any suspicious files appearing in your phone’s quarantine folder. When you reach this stage, you can proceed to step 3.

Step 3. Keep Your Devices Protected From Other Threats

Now that you’ve removed all of the malware from your Android phone (or protected your iOS device using an antivirus program like Norton), you need to take precautions to prevent more malware or security threats.

  • Keep your antivirus running. Having your antivirus running in the background lessens the risk of downloading more malware and protects you from phishing websites, smishing attacks, data theft, and more.
  • Keep your smartphone up-to-date. If your smartphone is using old firmware or outdated apps, it’s vulnerable to exploit attacks. When developers find vulnerabilities in software, they patch them through software updates.
  • To update your Android device:
  1. Open Settings.
  2. Scroll to the bottom of the menu and tap System & updates (on some versions of Android, the button is just called System).
  3. Tap Software update.
  • To update your iOS device:
  1. Tap Settings.
  2. Tap General.
  3. Tap Software update.
  • Enable real-time protection. A good antivirus will include real-time protection that constantly monitors and scans files to stop them from causing damage to your device.
  • Use phishing protection. Phishing protection recognizes dangerous websites and stops you visiting them, so cybercriminals can’t steal your data using deceptive sites.
  • Make sure your antivirus includes ransomware protection. The best antivirus apps can protect your apps and files from being locked by ransomware. Norton and McAfee all successfully blocked simulated ransomware attacks in my tests.
  • Only download files from official storefronts. The Apple App and Google Play stores verify apps before they’re published to their storefronts, so you’re unlikely to download anything malicious. For an extra layer of protection, Norton has an App Advisor for Android that alerts you if anything suspicious has made its way to the Google Play store. You can also safely download Android apps from Amazon’s app store.
  • Secure your Wi-Fi Network and IoT devices. Your wireless network and internet of things (IoT) devices should be secured by a strong password. If someone can access your IoT device or home network, they can access the information stored on that network or device. Password managers such as 1Password generate strong passwords and encrypt and store them so hackers can’t steal them.

What to Do If Malware Has Blocked Your Smartphone (& You Can’t Run an Antivirus Scan)

If malware has blocked your smartphone, you have a couple of options. If you’re using Android, you need to boot your device into safe mode, and either delete any recently installed apps, or factory reset your device.

If you’re using iOS, you can connect your phone to a Mac or Windows PC and restore it via Finder or iTunes.

Click on the relevant option below:

Restore a Blocked Android Device

To access a blocked Android, you first need to boot your phone into safe mode. The steps to do this vary depending on your phone’s model:

  1. With your phone powered off, press and hold the power and volume-down buttons. Your phone will either boot into a recovery menu, or directly into safe mode. If it doesn’t, try this step again, but hold the power and volume-up buttons instead.

Note: If both methods fail, check online (or in your phone’s manual) for specific instructions on how to boot into safe mode.

If your phone boots into a recovery menu, you can use the volume keys to navigate. Navigate to Safe mode, and press the power button to boot your phone into safe mode.

  1. With safe mode running, navigate into your phone’s settings. Tap Apps twice, then scroll through your list of installed apps. Uninstall any suspicious apps by tapping on them and then tapping Uninstall.
  2. Try rebooting your phone normally to see if it starts. If it does, you should run a malware scan by following our above steps.

If your phone still doesn’t start, you need to factory reset your device. Follow step 1 above to boot your phone back into safe mode, then follow the steps below:

Back up your data:

  1. Tap Settings.
  2. Tap Google.
  3. Tap Backup.
  4. Tap Back up now.

Note: If you want to back up photos and videos, ensure “Photos & videos” is set to On.

Reset your device:

  1. Tap Settings.
  2. Tap System & updates.
  3. Tap Reset.
  4. Tap Reset phone.
  5. When asked to confirm, tap Reset phone again.
  6. Wait for the device to reset to its factory default settings.

Once you’ve done this, you can restore your recent backup. Follow the on-screen steps after the factory reset to restore it. When finished, it’s a good idea to install an antivirus program like Norton so this doesn’t happen again.

You can now move on to our other smartphone security recommendations.

Restore a Blocked iOS Device

Accessing a blocked iOS device is easy. To access a blocked iOS device, you need to turn your iPhone off, and connect it via USB to your Windows or Mac computer. Once you’ve done this, follow these steps:

  1. Open Finder (Mac) or iTunes (Windows).
  2. Put your iPhone into DFU mode. The steps to do this vary depending on your model. The following works with the latest iPhone models:
    1. Quickly press the volume-up button.
    2. Quickly press the volume-down button.
    3. Hold down the side button. When your iPhone’s screen turns off, hold down the volume down button while still holding the side button.
    4. Wait about 5 seconds, then let go of the side button only (if you see the Apple logo appear, you held the side button down for too long).
    5. Nothing will happen, but Finder or iTunes will detect the device in DFU mode.

Note: If this doesn’t work, look up your iPhone by its model number online (e.g. iPhone 6) and follow instructions on booting into DFU mode while your phone is connected to a computer.

  1. Finder/iTunes will automatically detect something is wrong with your phone, and you’ll be given the option to restore it. However, be aware that doing so will delete all of your data.

Note: Unless you backed up all of your data to iCloud prior to your phone being bricked, the only way to recover your data before restoring your iPhone is to use third-party apps like EaseUS MobiSaver. These apps can scan your iPhone from your computer, and allow you to restore files that you can’t access — but there’s no guarantee they’ll work. That said, you can download apps like EaseUS MobiSaver on a free trial so there’s no risk in trying them out.

Either way, once your iPhone is restored, you should be able to restart it normally. When you’ve done this, install a mobile antivirus such as Norton to prevent malware from blocking your phone in future.

Other Smartphone Security Recommendations

You should have followed our above security recommendations by now, and your Android or iOS device should be free from viruses and other malware. However, there are a few more security recommendations you should consider:

  • Install a password manager (such as 1Password).
  • Install a secure VPN (such as ExpressVPN).
  • Enable two-factor authentication (such as biometric login).
  • Optimize your phone’s privacy settings.

Installing a password manager (such as 1Password) allows you to store your passwords in a secure vault. You can also store personal data, such as financial information, passport numbers, and driver’s licenses. Password managers store this data using 256-bit AES encryption, meaning hackers can’t steal your data. They also generate and remember super strong passwords, which are impossible to crack using botnets like Mirai.

You should also consider using a good virtual private network (VPN), such as ExpressVPN. VPNs give you a virtual IP address so cybercriminals can’t see your location. By connecting to a server in a different country, you can even make it look like you’re accessing the internet from somewhere else. The best VPNs also have servers in many countries.

Activate two-factor authentication (2FA) to bolster your device and account security. This method requires a secondary identification method, like an email or phone number. Advanced 2FA also allows you to protect your accounts with an authenticator app like Authy or a physical USB key such as YubiKey.

To enable 2FA on Android, follow these steps:

  1. Open your Google Account.
  2. Tap Security.
  3. Tap Signing into Google.
  4. Tap 2-Step Verification.
  5. Tap Get started.
  6. Follow the on-screen instructions.

On iOS:

  1. Go to Settings.
  2. Tap your account name.
  3. Tap Password & Security.
  4. Tap Turn on Two-Factor Authentication.
  5. Follow the on-screen instructions.

You should also check your phone’s privacy settings.

On Android:

  1. Open Settings.
  2. Tap Privacy.
  3. Adjust what data individual apps can access.

If you’re on iOS:

  1. Open Settings.
  2. Tap Privacy & Security.
  3. Tap App Privacy Report.

This provides you with a report that outlines all the current permissions of your iOS apps, simplifying the process of making changes that enhance your security. Additionally, with Norton 360 Deluxe, the Privacy Monitor will provide you with a list of data brokers who are selling your personal identification information (PII) and ask for your exclusion from any database.
