Well, it turned out that not all of them were than bad and antivirus software managed to remove them from your computer, alongside all their threats. Today, we moved to smartphones. Since we use them most of the day, some badintended guys though about exploiting this and developed some pretty nasty bits of code which could get into our Android powered phones and do bad things. Just think about how much much information is stored on your smartphone: emails, passwords, bank accounts and many more. Yes, ladies and gentlemen, we’ve reached that point in which we are talking about smartphone viruses, hunting down your data.
Apparently, there’s a pretty big amount of Android malware running free on the Internet right Apparently, there’s a pretty big amount of Android malware running free on the Internet right now, but if you’re well informed, you can keep your phone virusfree, without the risk of exposing your data and other valuable information. So, without much further ado, here you can find everything you need to know about Android viruses: what are they, how dangerous can an infection be, how to get rid of them and, most important, how to stay away from such things. Or, simply put, the ultimate Android virus guide, provided by UnlockScope, the easiest, fastest and safest method to unlock your phone, giving you the freedom to use it with the carrier of your choice and helping you save hundreds of dollars when you travel internationally. What’s an Android virus? First of all, let’s make one thing clear: Android viruses are not technically viruses.A virus is a chunk of code hidden in something that appears to be useful, like some kind of magic file management tool. After it’s installed or accessed, it starts spreading like crazy all over your hard disk. Remember the good ol’ days when some of your friends had a pretty interesting status on Yahoo! Messenger, which, right after being clicked, led you to a fishy site and bam!, you were infected? That’s an example. On Android, things work a bit different, using the sandbox approach. In order to start executing a process, an app requires approval from the user. Still, not even after receiving it, accessing data from anywhere cannot be done, so the infestation cannot take place either. Therefore, currently we don’t have any Android viruses. Currently, yes, as we don’t exclude the scenario in which, somewhere in the future, someone figures out a way to trick this sandbox approach and apps will start installing without the user’s approval. The things you need to stay away from, as an Android user, are malware, adware, spyware. Also, we’re going to focus a bit on ransomware too, since this is maybe the most dangerous type of virus you can encounter.
Malware This is what you should avoid at all costs. According to Wikipedia, it’s short for malicious software and represents any software used to disrupt computer operation, gather sensitive information, or gain access to private computer systems. What malware does is collecting data and send it to servers you don’t recognize. Still, don’t forget that it can’t do this if don’t authorize it. Ok, so how on Earth does it end up doing such horrible things? After all, you see all the permissions it requires when installing it, right? It doesn’t say anywhere “Requests access to your credit card number” or something like that. Well, it kinda does, but the thing is that you can’t see where it says this. Usually, it uses text the same color as the background when it shows you the permissions, which is very hard to detect. Not to mention that there are basic apps out there, like the ones you use for wallpapers, which require pretty weird permissions. As yourself some questions before granting them access to your data. Hot to get rid of/avoid malware There are a couple of Android antivirus applications that can do this. They come with a database of malware instances and once you install them, they start looking for their signatures and try to uninstall them.
If you don’t want to try this type of apps, pay a lot of attention before installing anything on your If you don’t want to try this type of apps, pay a lot of attention before installing anything on your phone. Google is known for constantly checking the Play Store for apps which could harm your phone and data, but once again, make sure to read the reviews and all the permissions required before installing one. You can find more details about how to protect your Android device from malware in Dan Graziano’s excellent article, written for CNET. Adware According to Bill Snyder, from Info World, this is actually the biggest threat for Android phones! You’ve definitely came across it, as it can take different forms, like popup messages that look like system notifications, informing you that your phone is running slow and inviting you to install an app to solve the problem. Sounds familiar, isn’t it?
You you are uninspired enough to actually tap on them, you will be redirected to some suspicious You you are uninspired enough to actually tap on them, you will be redirected to some suspicious app stores and end up with an app that will send premium SMS, behind your back, and collect tons of data, according to Avast’s malware analyst Filip Chytry, cited by BBC. Keeping it short, stay away from any ads that promise waytoogoodtoseemreal solutions for your phone’s problems, various prizes and generally, free stuff. How to get rid of/avoid adware Even though it might seem stressful, you can actually get rid of those pesky apps. First of all, do the first thing that you can think off: uninstall it. But don’t use the classic way! Go to your phone’s Settings menu > Apps > Application manager. A list with all your apps, including the malicious one will show up. If there’s anything you know you haven’t installed, that/those are the one/s you should uninstall. The thing is that all this malicious apps leave traces, so you’ll have to clean after them. In order to do this, you can try a few dedicated antivirus apps, but make sure they’re made by reputed companies, likeAvast, for example. Their free Mobile Security app will scan your phone and get rid of any potential threats. Spyware Spyware is something pretty similar to adware, as in most cases, it doesn’t do anything else than what’s advertised. Also, almost all smartphones have spyware on it, at some level. You didn’t see that coming, we bet. They do get to know your location and other details you allow them to when installing them, right? Besides this, they collect data, in order to send you relevant ads, which can be a good thing if you actually click on inapp ads. Another category of spyware is carrier spyware. Carriers like to know how you’re using a phone, so most carrierbranded devices can see everything you’re sending through a specific network. But once again, don’t panic, as they use this data in order to improve their services
How to get rid of/avoid spyware This is easy. Just pay a lot of attention to the permissions apps require when installing them. As for carrier spyware, you can flash a custom ROM, but unless you know exactly how to do it, our recommendation is to avoid this. Ransomware Finally, a malwaretype virus that caused a lot of trouble is ransomware. Besides preventing or limiting users from accessing their system, ransomware forces its victims to pay the ransom through certain online payment methods in order to grant access to their systems, or to get their data back. Some ransomware even encrypts files (called Cryptolocker), as stated by WikiPedia. Until now, ransomware viruses were targeting only computers, but they’re becoming present on Android smartphones too. According to Ruchna Nigam, Security Researcher at FortiGuard Labs, made a short list with three of the most dangerous ransomware viruses for Android: Fake Defend – Discovered in July 2013, it acts like a fake antivirus app, asking users to pay for a license after a fake scan, showing a list of viruses apparently present in the system. Effects: If the user decides to pay, credit card details are copied to the server. In addition, whether or not the user pays, the virus closes certain services and other processes associated with the antivirus. Eventually, it will damage Android system apps installed on the SD card, with the ability to delete any application and ROM backup. Finally, after six hours after installing, the phone’s screen will lock and the lock/unlock button won’t work anymore Phone use after virus infiltration: Difficult initially, impossible after six hours Ransom: $99.98, payable with credit card Uninstalling: Impossible without resetting the device to factory settings Damage to user data: User data won’t be damaged, but the backup will be lost.
Cryptolocker – Discovered in May 2014, it appears as a video download app called BaDoink. Cryptolocker – Discovered in May 2014, it appears as a video download app called BaDoink. Even it if the virus does not harm your data, it will display a customized lockscreen, depending on your geographical position. The lockscreen is lit every 5 seconds, leading to a faulty phone use. Phone use after virus infiltration: Difficult Ransom: $300, via MoneyPak Uninstalling: Reboot in Safe Mode and reset to factory settings Damage to user data: User data will not be lost Simplocker – Discovered in June 2014, it appears as an app infected with a Trojan, such as Flash Player. This is actually the first real ransomware virus for Android, as it’s able to encrypt your phone’s files. Infested devices are locked and the display shows a message claiming that you need to pay in order to unlock your phone. Effects: Encrypts files with extensions like .jpeg, .jpg, .png, .bmp, .gif, .pdf, .doc, .docx, .txt, .avi, .mkv, .3gp or .mp4, triggering the AES algorithm. The virus is using the TOR software to communicate regularly with a server that responds to deactivating commands. Phone use after virus infiltration: Difficult Ransom: 100 rubles, via Qiwi Wallet Visa Uninstalling: Reboot in Safe Mode and reset to factory settings
Damage to user data: Files are encrypted How to get rid of/avoid ransomware After your phone is infected with ransomware, you might deal with some serious issues, so our recommendation is to make sure that your phone is 100% protected against this threat. Use a functional antivirus, preferably one made by a reputed company. It should prevent or at least warn you about installing infected apps. Finally, install apps just from trusted sources and developers. Stick to the apps from the Play Store and if you’re in doubt, user comments can provide a lot of extra details.
