    How to remove a virus from an Android tablet

    Use an anti-malware cleaner to get rid of viruses and malware on an Android tablet. Tablets run the same operating systems as phones, so the virus removal process for an Android tablet is the same as it is for an Android phone. Jump back up to the steps above to remove malware from Android to get rid of viruses and other security threats to your tablet.

    Last resort: wipe your Android

    If the steps above don’t work, try resetting your phone to its default factory settings. But a factory reset should be a last resort — before resetting your phone, try using an Android virus removal app instead. If you’re ready to wipe your Android, here’s how to get rid of viruses on your phone by factory resetting your Android:

    1. Reset your phone.

      Open Settings, select System, and tap Reset options. Choose Erase all data (factory reset) and then tap Erase all data. Confirm via the pop-up and then restart your phone.

    2. Restore your phone.

      If you have a backup available, you can restore your phone to get your data back. Simply rebooting your phone isn’t enough — you need to restore from a backup from before your phone started acting strangely, otherwise you risk installing the Android virus or malware again.

    Can Android phones get viruses?

    No, Android phones can’t get viruses that self-replicate. But Android devices are vulnerable to other types of malware that can cause even more chaos on your phone. From malicious adware to spying apps and even Android ransomware, Android threats are widespread.

    One of the reasons Android phones are susceptible to malware is because Android struggles with updates. Updates are important because they often contain critical security fixes to bugs or other operating system vulnerabilities.

    Downloading apps from third-party sources also increases the risk of installing a virus or malware. Android’s open-source platform and delayed update rollouts are two major reasons why you should always use strong Android antivirus software to clean your phone of any viruses or malware.

    How to check your Android devices for viruses or malware

    Do you have a virus on your phone? If you notice a strange app or unexpected behavior on your Android device, don’t wait to find out – the faster malware is discovered and removed, the better.

    Here’s how to detect potential infections on an Android phone or tablet:

    1. Download free mobile antivirus.

      The best way to check for malware on your phone is to use a mobile security app like free AVG Antivirus for Android.

    How to remove a virus from an iPhone

    A lot of iPhone malware is caused by hackers manipulating your browser. That’s why clearing your browsing history and data can help resolve iPhone virus issues. But to remove iPhone spyware and more insidious malware threats, you’ll likely need to restart your iPhone, update iOS, restore your phone to a previous backup, or perform a factory reset.

    If you think your iPhone has a virus, here are a few ways to get rid of the malware infection:

    1. Clear your browsing history and data.

      Open Settings, scroll and tap Safari, and then tap Clear History and Website Data.

      Repeat this process for any other browsers you use.

      Clear Safari's history and website data to get rid of annoying pop-ups or error messages.

      Restarting your iPhone can fix a lot of issues.
    3. Update iOS.

      Go to Settings > General > Software Update. If you see a software update, install it.

    4. Restore your iPhone to a previous backup.

      Go to Settings > General > Reset, then choose Erase All Content and Settings. Follow the prompts to restore your iPhone from a backup. Choose a backup you created from before your phone began acting strangely.

      To restore your iOS as a new device, first go to settings and select "general" then "reset."
    5. Reset your iPhone to its factory settings.

      If your iPhone is still acting up, go to Settings > General > Reset, and choose Erase All Content and Settings. Here, rather than restore from a previous iCloud backup, choose the option to reset your phone.

    6. Install an iOS security app.

      iOS is very secure, but you can make it even better with a dedicated security app. AVG Mobile Security for iPhone and iPad will safeguard your passwords, protect your Wi-Fi network, and make sure your private photos stay private, even if your phone is lost or stolen.

    To remove a virus from an iPhone, follow these steps.

    How to remove a virus from an iPad

    iPads use the same iOS operating system as iPhones, so the virus removal process is the same as the steps for removing a virus from an iPhone. First try deleting malware from your iPad by clearing your browser history and data. Then reboot your tablet and update to the latest version of iOS.

    If you still see the warning signs of an infection, try restoring from a backup or performing a factory reset. And make sure to install an iOS security app to clean up all traces of malicious code, as well as detect and prevent potential threats in the future.

    Can iPhones/iPads get viruses?

    iPhones viruses are extremely rare, because self-replicating iPhone malware is scarce. And unlike the Android operating system, the iOS platform is a closed system, so it tends to be a bit more secure than Android, which is an open-source platform.

    But while iPhones are less vulnerable to malware than Androids, there are other security risks. Spyware like Pegasus, trojans (sometimes called “trojan viruses”), phishing attacks, and unsafe Wi-Fi networks are just some of the threats that can affect your iPhone or iPad.

    Jailbreaking your iPhone — removing Apple’s built-in, manufacturer restrictions — makes it just as vulnerable to malware as an Android device. So if you jailbreak, it’s important to learn how to do a virus scan for your iPhone. But even without jailbreaking your phone, iPhone users are still vulnerable to other serious security threats — like identity theft.

    A well-known 2021 iPhone hack installed spyware known as Pegasus that can steal mountains of personal data and turn your phone into a permanent surveillance device. Using a security exploit to leverage vulnerabilities in iMessage and WhatsApp, Pegasus can bypass iOS’s built-in security system. The hack was created by Israel’s NSO Group, one of the world’s most advanced hacking groups.

    We strongly recommend using a robust mobile protection app for iPhones and iPads. AVG Mobile Security for iOS goes way beyond antivirus or malware protection, with anti-spyware tools and other advanced features that keep you safe whenever you’re online.

    How do I know if my phone has a virus or malware

    Unusual behavior and unfamiliar apps are the two biggest warning signs of phone viruses and other malware. These signs will tell you if your iPhone or Android device has a phone virus.

    • Adware pop-ups: Most ads can be blocked with an ad blocker or a privacy-focused browser like AVG Secure Browser, which comes with a built-in ad blocker.

      If you’re seeing pop-up ads on your Android or iPhone even when your browser is closed, you could have adware, which is a type of malware that spams you with extra ads.

    • Excessive app crashing: Many apps crash periodically, but if your apps start crashing regularly for no apparent reason, your phone could be infected with malware. Removing malware won’t just restore your privacy and security; it will also help speed up your iPhone or Android and improve overall performance.

    • Increased data usage: If you notice a sudden spike in data usage, that could be a sign that malware is running background tasks on your device or transmitting information or background data from your phone. Remove the phone virus to help control your mobile data usage.

    • Unexplained phone bill increases: Some malware strains attack by sending premium-rate SMS messages from your phone, causing your phone bill to skyrocket. Ztorg Trojans were found doing this in 2017, in addition to deleting incoming messages.

    • Your friends receive spam messages: Some malicious software can hijack your messenger service and spam your contacts with infected links. If your contacts tell you they received a weird message from your accounts, investigate right away.

    • Unfamiliar apps: If you notice an app on your phone that you don’t remember downloading, stay away. Fake apps are a common symptom of malware on Android phones, and they should be uninstalled immediately. An anti-malware phone scanner will take care of this in a few quick taps.

    • Faster battery drain: Malware mischief can use up a lot of energy, rapidly depleting your Android or iPhone battery. If your battery is dying faster than usual, malware might be the cause — removing it will free up space and improve the battery life of your phone.

    • Overheating: While the majority of the reasons your phone is overheating are normal and relatively harmless, it’s also possible that the cause is a malware infection. Resolving privacy and security issues can also help you fix an overheating iPhone or Android.

    What can viruses do to your phone?


    • Increase your data usage and rack up unexpected charges by sending spam or premium SMS messages, or subscribing you to unauthorized or premium apps or services.

    • Spam you with ads that generate revenue for the attacker.

    • Install rootkits that give hackers a backdoor to your phone.

    • Record phone conversations and send them to hackers.

    • Collect personal information, including your GPS location, contact lists, photos, email addresses, and banking details.

    • Use keyloggers to record your login credentials, including your passwords.

    • Take over your device through rooting.

    • Infect you with ransomware, locking you out of your files.

    Before you install a new app, check if it’s safe. Read both user and professional reviews to learn what other people think. Some apps might be clean when you download them, but later get infected with malware through updates — so it’s important to stay alert.

    How to protect against phone viruses


    • Download apps from trusted sources: Google and Apple both vet apps for security before allowing them into their stores. Avoid third-party app stores, and don’t jailbreak your iPhone or root your Android phone unless you’re willing to take the risk.

    • Check apps for safety: Malicious apps occasionally find their way onto the official app stores. You should always check apps for safety before downloading them. Review the developer profile, read user reviews, and check the download count. Be extra careful when downloading anything brand-new, and don’t download from questionable developers.

    • Research before you install: User reviews are great, but you can also see what the pros have to say. Consult expert reviews and independent evaluations of any new app before putting it on your phone.

    • Keep your phone updated: Software providers often issue updates to fix bugs and plug security holes. Always update your phone’s operating system and apps with the latest versions.

    • Don’t click suspicious links: Suspicious links in emails, text messages, or on social media can contain malware. Don’t click on any links you don’t expect to be there.

    • Be careful on public Wi-Fi: Unsecured public Wi-Fi networks make it easy for hackers to intercept your traffic. Avoid doing anything sensitive on public Wi-Fi unless you’re using a VPN and other privacy apps.

    • Use cybersecurity protection: Whether you have an Android or iPhone, a security app will help protect you against malware, phishing, and other mobile threats.

    FAQs

    What is a virus?

    Viruses are a type of malware designed to infect computer systems and use the resources of their host machine to self-replicate and spread to other devices. Viruses were one of the first computer threats to emerge, and despite the rapid growth of other forms of malware in recent years, hackers continue to develop new viruses to exploit vulnerabilities in computer systems.

    How can I scan my phone for viruses?

    Use AVG Antivirus for Android or another dedicated malware and virus removal tool to scan your device from top to bottom, find and remove all kinds of malware threats (including adware, spyware, and Trojans), and stop malware from infecting your device again.

    Can my phone get a virus from a website?

    The chance of a website infecting your mobile device with a virus is low, but it’s not impossible. And without a top Android or iPhone security app, other forms of malware designed to target specific security exploits pose a real threat. To browse securely, protect your device with a mobile security app and always follow website safety guidelines.

    Does Google or Apple send virus warnings?

    Neither Apple nor Google send virus warnings. If you receive spoofed notifications, emails, or other virus warnings supposedly from Apple or Google, these are scareware tactics designed to use social engineering to manipulate you into inadvertently downloading malware, revealing personal information, or handing over your money.

    Can hackers see through my phone camera?

    Certain types of spyware and other malicious software tools can let hackers access your phone camera and other parts of the device — potentially letting them spy on you in real time. Protect yourself with a dedicated anti-spyware tool, and avoid falling prey to snoops by browsing safely on public Wi-Fi networks.

    Does resetting a phone remove viruses and other malware?

    Simply restarting your phone won’t wipe malware from your device, but restoring your device to its factory settings probably will. If you’re going to factory reset your device, back up your data to avoid losing it all. If you restore your phone from a backup, previously infected files could continue to infect your restored device. Use a malware and virus removal tool and clear your phone’s cache, delete your cookies, and clear your browsing history to get rid of any lingering harmful internet files.
