Android viruses are rare, but they exist. Smartphones and tablets are as vulnerable as regular computers. The common way viruses like Gunpoder, Ghost Trojan, Googlian and Godless infect your android device is through apps, but mazar sneaks in via a text message prompting you to download the Tor browser (guess what, you are not downloading the Tor browser).
Android viruses have various aims; some run malicious processes on your device, others steal your personal information while others download additional software, which may not always be malicious. However, whatever they’re up to, you don’t want them there.
HOW TO AVOID ANDROID VIRUSES
- Check app permission: Irrespective of where you are downloading an app always check required permissions before hitting install. Why does a video player need to see your contacts? Capital letter “NO”. You can also check online reviews and browse the developer’s website to see whether it’s is genuine operation.
- Don’t install apps that are not from Google Play unless you know what you’re doing : This functionality should be disabled by default , but to check you can open your phone or tablet’s Settings menu : go to security and then ensure the Unknown sources option is disabled
- Avoid cloned apps: 99% of the time you will be safe downloading apps from Google play, but malicious code has been found within apps there. Avoid downloading what appear to be cloned apps from unknown developers, apps that simply don’t do what they say they do.
Try to always keep your android up to date. It helps.
SYMPTOMS OF AN INFECTED DEVICE
Data Usage: The first sign that your phone has a virus is the rapid depletion of its data. That’s because the virus is trying to run a lot of background tasks and communicate with the internet. If you don’t have an unlimited data plan, this could cost you money, because you may have to buy extra data to keep up with all that wasted processing time. Essentially you are paying to let a malware ruin your device and wreak havoc on it .
Crashing apps: Viruses tamper with the regular operation on your phone making your apps crash. There you are, playing angry birds and your phone crashes. That’s strange. It never used to happen. After the game crashes a few more times, you should start to suspect virus.
Pop-ups: Many website have pop-ups Ads. But if you start seeing pop-ups all the time, especially for product or services that seem suspicious, you may want to check for a virus. Whatever you do, don’t click on the links. Virus based pop-ups are most times designed to make your device even sicker.
Unwanted apps: True to their name, Trojans look legitimate. They are designed to look like real apps and avoid detection. If you see an app that looks familiar, but you don’t remember downloading it, check to see if it’s authentic. If it looks fishy, delete it.
Battery drain: Apps affected with virus take a lot of energy. Not only does your phone use more data, but the battery runs out faster.
WHAT TO DO WHEN YOU DISCOVER YOUR PHONE IS VIRUS AFFECTED
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.
Open your Settings menu and choose Apps, then make sure you’re viewing the Downloaded tab. Chances are you will know when your device started misbehaving, and you can usually line that up with a new app you might have downloaded.
If you don’t know the name of the app you think has infected your Android phone or tablet, go through the list and look for anything dodgy or that you know you haven’t installed or shouldn’t be running on your device.
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 and 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. Exit the Apps menu and tap on Settings, Security, and Device Administrators. Here you’ll find a list of any apps on your phone or tablet with administrator status.
Simply un -tick 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.
If you do not get the steps correctly, take your phone or tablet to a professional engineer.
I don’t believe in antivirus on Andriod gadget, but it can give you peace of mind if you’re concerned about viruses. Be warned that android antivirus is known to occasionally report false-positives.
