Fake anti-virus, also suggestively known as scareware, tricks you into paying money by pretending to find threats such as viruses and Trojans on your computer.
The scan to find the “threats” is free; the cleanup part is not.
If you do pay up, the software then pretends to remove the non-existent threats so you may not even realise that you’ve been scammed, on the principle that all’s well that ends well.
But not only are you out of pocket, typically between $40 and $100, you’re also led into a false sense of security, because the clean bill of health provided after you’ve paid is as bogus as the infection report at the start.
This sort of scam is most common on Windows, with OS X a long way back in second place. But other operating systems aren’t exempt from the depredations of cybercriminals.
SophosLabs recently acquired an Android scareware sample going by the entirely hokum name of Android Defender. It’s not particularly polished, and it crashed quite a bit as we played with it, but it does show that the scammers have an active interest in the Android ecosystem.
I thought I’d give you a guided tour of what it looks like. That way, you’ll have some pointers that I hope will help you determine real from fake security software in future.
I started by creating a fresh Android 4.2.2 emulator image and firing it up.
Then I installed the malicious APK (Android Package file). In real life, you might be encouraged to download it from a handy website; I just used the Android Debug Bridge (adb) to inject it from my research computer into the emulated image.
You can see the application icon at top left, since its name conveniently starts with ‘A’.
I launched it to see what would happen. It advised me that my device “is at risk of being infected,” which is an understatement: my device is already infected, because Android Defender is on it.
I’m invited to buy, but there’s no serious pressure yet.
The inital scan quickly suggests I have a problem.
Two viruses, one Trojan and a Malware, to be precise.
You might be inclined to believe this report, since the “threats” found are Android malware names you might have heard of.
But it’s all smoke and mirrors. You don’t have to be a Java coder, or even a programmer at all, to spot in the source code below that the app is using the Math.random() function to build up a list of virus names to report later.
The malware names are field-updatable, stored in Russian and in English in an XML data file that is part of the malware’s APK file.
This is about as close to “malware identities” (also known as signatures, patterns or definitions) as you will find in the app.
There isn’t anything to help the product actually locate viruses in infected files. There’s just a list of names: when you’re choosing randomly even on uninfected devices, recognition patterns just aren’t needed.
Most of the viruses on the list are existing Android malware names, in order to add a ring of verisimilitude. But somehow the Windows-only virus Conficker managed to get in there.
The pressure on me to register the product is increasing, because it’s now time to think about cleaning up the malware.
So I gave it my best shot, and tried to “activate” the software.
The buy page wasn’t working, so I can’t tell you how much the scammers intended to charge.
But it didn’t matter, because I had an activation code up my sleeve from the source code itself.
We saw this happy-go-lucky attitude to activation in early Mac scareware.
Was the activation system this simplistic for experimental convenience, or is it just a prototyper’s indolence? We shall probably never know.
The product crashed after I clicked the Activate button, but when I started it up again, I found that the activation had worked and my device was “fully protected.”
The next system scan is no longer a scary red but a go-ahead green.
Better still, the app is pretending to have “eliminated” the malware it “detected” earlier.
In fact, the software builds a small sqlite database in which it remembers what viruses it has “found”, and whether it has fraudulently “cleaned” them, so it will be consistent in its dishonesty.
There’s a half-hearted privacy manager tool built in to the app, presumably because that’s the sort of feature that other Android security products provide.
And there’s an update page, though the crooks forgot to translate that part properly.
The update pretends to work, even listing signature files it supposedly downloaded from the internet.
(In my case, it couldn’t have downloaded anything from outside – I tested in with my device in Airplane Mode, which inhibits all outbound connections. That cuts you off in the emulator, just as it would on a real device.)
Updates are only simulated once a day, in order to appear more realistic.
The app pretends that its pattern database has increased in size every time you update. Once again, the Java pseudorandom number generator is used behind the scenes.
I don’t imagine you installed this progam, but if you did, you need to remove it right away.
And you couldn’t have installed it without first telling your device that you wanted the freedom to go looking for software outside Google’s own official Play Store.
I’d suggest, if you did so (since it ended badly enough for you to get this malware!) that you turn “Unknown sources” off once again.
And you might want to consider installing a proper Android security tool in which the detection and the cleanup are free.

Sophos Security and Antivirus is available from the Play Store, so you don’t need to enable “Unknown sources” to install it.
And yes, it does actually look for threats before it reports them.
If it finds a threat, there aren’t any demands. Just a warning and an instant “Uninstall” button.
In the words of many a Naked Security video and podcast, thanks for listening, and until next time, stay secure!

Does my Android phone have a virus? Is it infected with malware or a malicious app? Will my personal information be held for ransom? If you find yourself asking these questions, then here is some useful information about Android devices and antivirus apps that may help you.
Viruses and other types of malware
Malware is malicious software that can sneak onto your phone. Written with the intent to cause harm, malware can include viruses, computer worms, Trojans, ransomware, and spyware.
Cybercriminals can use malware to access your personal data and, in some cases, subsequently use that sensitive information to commit identity theft or fraud.
Viruses are a particular type of malware that infiltrate a computer or other device and their programs. A cybercriminal may be able to install a virus on your device without your knowledge or consent. The virus may then be able to insert new, malicious code on your device that can monitor and manipulate your online activity.
What can viruses and other malware do to Android phones?
Malware is designed to generate revenue for cybercriminals.
Malware can steal your information, make your device send SMS messages to premium rate text services, or install adware that forces you to view web pages or download apps.
Info stealers can steal your contact list, your personal information, your location, your passwords, and more.
With the aid of malware, cybercriminals can access your devices and steal your information for their own use or to sell on the dark web.
Hackers also use ransomware to lock devices and encrypt personal data. Then they can demand a ransom payment from the victim in order to regain access to their files.
Signs your Android phone may have a virus or other malware
Phone Virus Prank
Phones can be vulnerable to damage externally and internally. While the external damage is usually visible, internal damage is usually hidden from view.
Malware like viruses are known to perform repeated tasks that can take up resources on your devices. Signs of malware may show up in these ways.
- Your phone is too slow.
- Apps take longer to load.
- The battery drains faster than expected.
- There is an abundance of pop-up ads.
- Your phone has apps you don’t remember downloading.
- Unexplained data usage occurs.
- Higher phone bills arrive.
How to check for viruses and other malware on your Android phone
A good way to check for malware on your Android phone is to run an antivirus scan.
Before buying antivirus software for your phone, make sure you consider the most comprehensive product that’s available for your device.
There are many antivirus software choices available on the market. Some are free, and some are sold.
It’s a good idea to do your research to ensure the security software you invest in runs a complete scan and doesn’t overlook any vulnerabilities. An incomplete scan could give you a false sense of security when, in fact, your device could be vulnerable to cyberattacks.
Norton Mobile Security for Android is one product you might consider.
How to remove viruses and other malware from your Android device
If you think you have malware on your phone, it’s important to stop the malware from causing any further damage. Here are a few steps you can take.
- Power off the phone and reboot in safe mode. Press the power button to access the Power Off options. Most Android phones come with the option to restart in Safe Mode. Here’s how, according to Google, although Safe Mode can vary by phone: Press your phone's power button. When the animation starts, press and hold your phone's volume down button. Hold it until the animation ends and your phone restarts. You'll see “Safe mode” at the bottom of your screen.
- Uninstall the suspicious app. Find the app in Settings and uninstall or force close it. This may not completely remove the malware, but it could prevent further damage to your device, or from it transmitting the malware to other devices on your network.
- Look for other apps you think may be infected. There’s a chance that some apps may have been infected by the malware. If you think you can identify those apps, delete them immediately.
- Install a robust mobile security app on your phone.
Tips to help protect your Android device against viruses and other malware
Here are seven key steps you can take to help protect against future risks.
- Invest in and use robust security software to protect your Android device.
- Keep all operating systems and software updated with the latest versions.
- Don’t click on suspicious or unfamiliar links in emails and text messages.
- Use strong, complicated passwords or a password manager.
- Never use unsecure Wi-Fi connections. Always use a VPN when connecting to public Wi-Fi.
- Always use strong cyber safety protection on all devices that connect to the internet.
- Always install apps from trusted sources, such as the Google Play Store. Read the fine print and permissions on the apps to understand how much access you are giving the app developers.
It’s a good idea to not wait until your device gets infected. Make protecting your Android device a priority. Having good antivirus software that helps protect your PCs, tablets, and other Android devices could help prevent malware from spreading from device to device.
