This guide walks you through how to perform an Android virus scan, what to do if you have an Android virus, or if you believe your Android has a virus or malware. If you know you have an Android Virus, or believe you have one, install an Antivirus app by using the steps below. Sep 18, 2017 It's always a good idea to scan someone's flash drive for viruses when you use it on your PC. Today we look at how to use Microsoft Security Essentials to scan thumb drives via the AutoPlay dialog. Sep 21, 2014 Before we proceed, you need to know that there are some services that let us scan files with multiple antivirus scanners online for free. Among them, VirusTotal is mostly popular and widely used. VirusTotal also comes with desktop, browser and Android tools. We will use VirusTotal's browser tool to scan files online for malware prior to download.
How to remove virus from Android: Summary
Android viruses are installed via third-party apps; to remove an Android virus put your device in Safe mode, if necessary remove its administrator status and then uninstall the affected app. If all else fails a factory reset will clear the infection. In this article we offer a step-by-step guide on how to remove malware from an Android phone or tablet.
How to remove virus from Android: Step-by-step guide
First of all, it's worth pointing out that it's unlikely that your Android phone or tablet has a virus. What you're more likely to be seeing is an ad that wants to convince you Android is infected and you need to download an app, or a dodgy pop-up, or perhaps your device is just misbehaving. But viruses for Android do exist.
If you're sure your device has a virus, read on to find out how to remove it.

How to avoid Android malware, including how to avoid Gunpoder virus, how to avoid Mazar virus
All Android viruses are delivered via apps installed on your device, so if your phone or tablet doesn't already have a virus, the best way to avoid it getting one is to never install software outside of the Google Play app store.
This is also true of the Gunpoder virus, which recently hit the headlines after Palo Alto Networks discovered it could sneak on to your phone via Nintendo game emulators installed outside Google Play - and even has the cheek to make you pay for the priviledge. Fortunately, Gunpoder hasn't been seen to affect UK users as of yet, but it's still worth taking measures to protect yourself from the Gunpoder virus and other Android viruses that may be released in the future.
More recently the Mazar virus has hit headlines, arriving on your phone via a link in a text message that downloads the Tor browser. Right now it appears to have affected devices only in Denmark, although it could potentially spread further.
Step 3 of 7:
To ensure you don't inadvertently install malware through the installation of apps outside of Google Play, open your Settings menu, look for the Security option, then ensure the option for Unknown Sources (allow installation of apps from unknown sources) is disabled. Also see: Security Advisor
If you're determined to install an app from outside Google Play, do your research. Check its permissions (does a video player really need to see your contacts?), look online for reviews and have a good look at the developer's site to see what else it offers. In the case of Gunpoder, be particularly wary of Nintendo game emulator apps.
You can also install an antivirus app, and plenty of free Android antivirus appsare available that are able to detect and remove malicious apps, for example 360 Mobile Security, Avast and Lookout. These all include an app scanner that will seek out anything dodgy, but note that these apps can also trigger false-positives - reporting an app you've been using for months as malware when you know it's fine. In most cases you can simply ignore these alerts. Also, again with Gunpoder in mind, these apps may not pick up on malicious behaviour if the app is able to hide it from them - Gunpoder uses the Airpush adware library to conceal that behaviour.
If you believe you already have a virus on your Android phone or tablet - perhaps one that is resisting your attempts to uninstall the associated app or even let you bypass the lock screen - a factory reset will remove it, returning your device to its out-of-the-box state. But doing so also means you'll lose everything on your phone that's not backed up. Instead, follow the below steps to remove a virus from Android.
Step 4 of 7:
How to remove a virus from Android
Put your phone or tablet into Safe mode. This prevents any third-party apps running, including any malware. On many devices you can press the power button to access the power off options, then press and hold Power off to bring up an option to restart in Safe mode. If this doesn't work for your device then you should Google 'How to put [your model name] into Safe mode' and follow the instructions. When in Safe mode you'll see 'Safe mode' at the bottom left of the screen.
Step 5 of 7:
Open your Settings menu and choose Apps, then make sure you're viewing the Downloaded tab. If you don't know the name of the virus you think has infected your Android phone or tablet, go through the list and look for anything dodgy-looking or that you know you haven't installed or shouldn't be running on your device.
Step 6 of 7:
Tap on the malicious app (clearly it won't be called 'Dodgy Android virus', this is just an illustration) to open the App info page, then click Uninstall. In most cases, this is all you need to do to remove the virus, but occasionally you might find the Uninstall button is greyed out. This is because the virus has given itself Device administrator status.
Step 7 of 7:
Exit the Apps menu and tap on Settings, Security, Device Administrators. Here you'll find a list of any apps on your phone or tablet with administrator status. Simply untick the box for the app you want to remove, then tap Deactivate on the next screen. You should now be able to return to the apps menu and remove that app.

With the virus now off your Android phone or tablet, all you need to is restart the device to take it out of Safe mode. Now that it's working correctly it's a good time to back up whatever important data you have stored on the device, and install an Android antivirus app to protect you from any future viruses that come your way.

Not sure how to tell if your phone has a virus? Mobile malware is on the rise, but by following a few simple steps it's easy to scan and remove viruses from Android phones and even iPhones. Learn how to stop pop-up ads and malicious Android apps in their tracks, as well as how to run a full phone virus scan.
Can Android phones get viruses?
Although Android mobiles don't get 'viruses' in the traditional sense, they are vulnerable to a whole host of malicious software that can cause chaos on your phone.
What's the difference?Computer viruses are malicious programs that infect and corrupt your programs and files, disrupt your computer's performance, and just generally wreak havoc on their electronic host. But what distinguishes viruses from other forms of malware is their ability to replicate, Agent Smith style. So far, self-replicating malware has not made its way onto Android phones or iPhones, meaning your phone can't technically get a 'virus' — this is just the go-to term most people use to explain any kind of malicious software.
Android malware comes in many forms, ranging from spyware, which gathers your personal data for third parties (often advertisers), to mobile ransomware, which holds your files hostage and demands a ransom in order for you to retrieve them.
Malware often makes its way into Android devices in the form of fake, malicious apps that either sneak into the Google play store or hide in other third-party app shops.
One of the reasons Android phones are susceptible to malware is Android's struggles with updates. Updates are important because they often contain fixes to bugs or vulnerabilities found in the operating system (OS). Android's open source system and delayed rollout of updates are two major reasons why Android users should always use an antivirus, like AVG AntiVirus for Android, as an added layer of protection.
Can iPhones get viruses?
The story for iPhones is a bit different: although iOS is generally not vulnerable to viruses or even many types of malware, there are other security threats you should guard your phone against.
What keeps iOS safer? Unlike Android, iPhone and iPad apps can only be downloaded through the official App Store. This prevents malicious software from infecting your device via fake apps.
Apps for iOS are also 'sandboxed', meaning they can't access data from other apps or break into your device's OS. Android sandboxes its apps too, but their approach is less restrictive than iOS, allowing apps to obtain more control over the device.
Additionally, iOS rolls out its updates to all devices simultaneously, which helps to plug holes and prevent security vulnerabilities, so hackers can't exploit them.
Does that mean it's impossible to get a virus on an iPhone? Well, thanks to Apple's safety precautions, it's extremely rare. But, malware can tunnel its way into an iPhone if the device is jailbroken, which allows iPhone and iPad users to download apps from sources other than the App Store (thus exposing them to potential threats). A jailbroken iPhone is just as vulnerable to malware as an Android device is.
Even without jailbreaking the device, iPhone users are vulnerable to other security threats, such as phishing, unsafe Wi-Fi networks, and identity theft. That's why we still recommend using a good mobile protection app for iPhones and iPads, such as AVG Mobile Security.
How to tell if your phone has a 'virus'
Malware, like viruses, is all about the stealth attack. It sneaks onto your phone like a thief in the night (or day, malware doesn't discriminate), lying dormant until you unknowingly activate it, or quietly (usually) stealing your sensitive information right from under your nose. It's up to you to be proactive and keep a lookout for symptoms that could indicate your device is infected. But don't worry — it's fairly easy to check your iPhone or Android device for malware.
1. Increased data usage
If you notice a sudden spike in data usage, this could be a sign that a virus is running background tasks on your device or trying to use the internet to transmit information from your phone. (While you're at it, find out how to keep your data usage under control on mobile phones).
2. Excessive app crashing

Apps crash from time to time, but if your apps start crashing regularly for seemingly no reason, your phone could have a virus/malware.
3. Adware pop-ups
Most pop-up ads are just annoying, not malicious. And the good news is that these can easily be blocked by using an ad block browser extension, or the free Opera Browser app, which comes with a built-in ad blocker. However, if you're seeing pop-up ads on your Android or iPhone even when your browser is closed, you could be dealing with adware: malicious pop-ups caused by malware trying to steal your data.

4. Unexplained phone bill increases
Some malware strains attack by sending premium rate SMS messages from your phone, causing your phone bill to take a hit. For example, Ztorg Trojans were found doing this in 2017, in addition to deleting incoming messages.
5. Unfamiliar apps
If you notice an app on your phone that you don't recall downloading, stay away! A common symptom of malware on Android phones, fake apps should be uninstalled immediately.
6. Faster battery drain
Malware mischief can use up a lot of energy, which subsequently takes a toll on your Android or iPhone's battery. If your battery is draining faster than usual, you shouldn't rule out a virus as the cause.
7. Overheating
While the majority of reasons your phone is overheating are normal and relatively harmless, it's also possible that the cause is a malware infection.
Watch out for malicious apps
Downloading a malicious app is the most common way for Android malware to get on your device. Once there, it can execute a number of nefarious deeds that may compromise your online security.
One of the most common strains of Android malware seen in recent years is Hummingbad. First detected in 2016, Hummingbad was initially spread through third-party app stores, though it eventually made its way onto the Google Play Store. It's main purpose was to get users to click on fake mobile and web ads in order to generate revenue for the Chinese ad firm behind the attack, Yingmob. The malware also installed rootkits, giving the hackers total control over infected devices and allowing them to download malicious apps onto the device without owner consent. Other fake apps, like fake games, wreaked similar havoc — like Finger Hockey for Android, which stole confidential info from players.
And while iOS malware is much rarer, it isn't nonexistent. In 2015, an iOS malware strain known as KeyRaider targeted jailbroken iOS devices. KeyRaider was most notable for stealing user information from over 225,000 Apple accounts, including usernames, passwords, and purchasing information, as well as disabling unlocking functionalities for iPhones and iPads. Even worse, KeyRaider encrypted some users' devices and demanded a ransom to unlock them (aka ransomware).
What malicious apps do on phones
These are just a couple of examples of how mobile malware can turn your device into a living hell, but don't worry, there are many more! Other forms of malware have been known to:
- Subscribe phones to premium services or send premium SMS messages.
- Record phone conversations and send them to hackers.
- Collect your personal information, including your location via GPS, contact list, photos, email address, banking details, etc.
- Rack up unexpected charges, through rapid data depletion, unusual SMS charges, or unauthorized app charges.
- Take full control of your device through rooting.
- Lock you out of your files and demand a ransom to release them.
So, before you download any shiny new apps, it's best to check if they're safe.

However, some apps might be clean when you download them, but later get infected with malware through updates. So it's important to stay vigilant.
How to remove a virus from an iPhone
Luckily, iPhone virus removal is fairly straightforward, since the virus or malware can't actually break into iOS. This is why most hackers go after software developer kits, which are then used to create apps — and the main reason behind why you shouldn't jailbreak your iPhone and download apps from outside the App Store. If you suspect a particular app may be compromised (maybe your problems started after you downloaded it, or it's redirecting you to web pages or the App Store without permission), you can try uninstalling it and seeing if that clears up the problem. If not, you have a few other options.
1. Clear history and data
This should help if you are experiencing pop-ups or 'Error' messages in your Safari browser. Simply go to Settings and scroll down to the Safari tab. Then tap Clear History and Website Data.
2. Power off and restart your iPhone
Nothing tricky about this — simply hold down your iPhone's power button, wait for the 'slide to power off' slider to appear, then slide to turn it off. To restart your phone, hold down the power button once more and wait for the Apple logo to appear. Yes, we're suggesting the good ol' 'turn it off and on again.' Trust us, it works!
3. Restore from an earlier backup
If the above methods don't fix the problem, try restoring your phone from an earlier backup (suddenly appreciating those incessant 'back up your phone' reminders right now, aren't you?). If your most recent backup isn't malware-free, you can try earlier backups until you find one that is.
4. Restore as new device
This is a last resort scenario, but if all else fails, then you can completely wipe your device and start fresh. Do this by going to Settings >> General >> Reset >> Erase All Content and Settings. And just like that, you can rise from the ashes like the resilient phoenix you are.
Always keep your iOS device protected
First of all, we recommend never jailbreaking your iPhone. Third-party apps are much more likely to put your device at risk, so you should really stick to what's available in the Apple app store. And speaking of apps in the Apple store…
Why not download a special app to help protect you? While your iPhone is unlikely to get a virus, there are many other threats out there. With the new AVG app developed especially with iOS in mind, you can ensure your passwords stay safe and uncompromised, check that a Wi-Fi network is secure before you connect, and even lock up your private photos so no one could access them even if your phone fell into the wrong hands. Ready to give it a try? Download AVG Mobile Security for iPhone and get started with free protection for iOS.
How to remove a virus from an Android phone
If you notice any of the symptoms mentioned above on your device and suspect you might have a virus, there are a few different methods you can try to remove it.
Run a phone virus scan
Google Play is full of antivirus apps that you can use to scan for and remove a virus from your phone. Here's how to download and run a virus scan using the free AVG AntiVirus for Android app, which scans apps and files for threats in real-time.
Step 1: Go to the Google Play Store and download and install AVG AntiVirus for Android
Step 2: Open the app and tap the Scan button
Step 3: Wait while the app scans and checks your apps and files for any malicious software
Step 4: If a threat is found, tap Resolve
Step 5: AVG will help you uninstall the malicious app
Manually uninstall malicious apps
Step 1: Go into Safe Mode
How To Scan A Download For Viruses On Android Phone
Like in Windows, going into Safe Mode on Android turns off access to all third-party apps to stop them from running. This is a great tool to help you identify the culprit behind your Android phone's unusual behavior — if the problem goes away when your phone is in Safe Mode, then you know a malicious app is to blame. Safe Mode also enables you to use your phone normally, without any interference.
While many Android phones will prompt you to Reboot to Safe Mode after pressing and holding the Power off button, others may require slightly more complex steps. If done correctly, you should see the words Safe Mode at the bottom of your phone's screen once it turns on.
Step 2: Identify the malicious app
Open your Settings and choose the Manage apps or Apps & notifications tab (or a similar variation). Go to the Downloaded apps or Installed apps tab and look for any apps that seem suspicious — for instance, apps you don't remember downloading or that shouldn't be running on your device. Maybe an app you downloaded around the time your phone started acting funky.
Step 3: Uninstall the malicious app
In most cases, you will simply be able to select the malicious app and tap the Uninstall button.
But if the malware or virus feels like putting up a fight, you may discover a greyed out Uninstall button, meaning it has acquired administrator access to your device. In this case, see Step 4.
Step 4: Remove administrator access
Go back into your Settings and look for Security. Tap Device Administrators (or something similar) and check to see if any malicious apps have access. If so, tap on the app and then remove access by either unchecking the blue box or clicking Deactivate. You can now uninstall the malicious app (go back to Step 3).
Always keep your Android device protected
The best way to prevent a virus or other form of malware from infecting your phone is to rebel against technology and stop using a smartphone. No? Okay, then if you use an Android device, you better make sure you're using a reliable antivirus app, such as free AVG AntiVirus for Android, that can scan your apps and files for any threats that may try to compromise your device or personal information.
Finally, as mentioned earlier, you should really avoid third-party app stores. Yes, malware does make its way onto Google Play from time to time, but this will still help Android users avoid the vast majority of threats.
