How to remove virus from Android (Pop-up Ads and Redirects Removal)

The number of Android apps infected with malware in Google’s Play store nearly quadrupled between 2012 and 2014. Make no mistake about it, there is such a thing as Android malware, cyber criminals create malware-spreading apps in devious attempts to steal personal details and advertisers use it as a marketing channel by bundling pushy ads with apps. In the first case, the users’ mobile security is clearly compromised. In the second one, the ad-app bundle is seldom mentioned, so users who download it unknowingly face a mobile privacy threat.

Can my Android phone get a “virus”?

So what about malware? Should we be worried? The key thing to remember about malware on Android is that you have to actually install the malicious app. Malware writers will use increasingly clever techniques to try and trick you into doing just that.
As malware writers try to earn money for their bad deeds, they continually look for new ways to get their malicious software installed on your devices. The best recommendation is still to think twice before installing untrusted software or clicking on strange-looking links.

Apps designed to personalize people’s Android-based phones are most susceptible to be compromised, as well as entertainment and gaming apps. Some of the most malicious apps in the Google Play store downloaded since 2012 were Wallpaper Dragon Ball, a wallpaper app, and the games Finger Hockey and Subway Surfers Free Tips.
Both Wallpaper Dragon Ball and Finger Hockey, have malware that steals confidential information such as device IDs from infected devices. Subway Surfers Free Tips, meanwhile, uses a Trojan called Air Push to bypass a device’s security settings and subscribe infected phones to premium services

When downloading apps it’s imperative that you only do so from a legitimate app store; that means from companies like Google Playstore, Amazon, Samsung, or another major manufacturer or carrier.
These marketplaces are monitored and scanned for potentially dangerous or fraudulent programs. On occasion, however, malicious apps sometimes slip through the cracks, often disguised as legitimate ones. A fake BBM app recently appeared in the Google Play store and managed to secure more than 100,000 downloads before being removed. The app itself was nothing more than a spamming service.

Pirated or cracked apps are another way that cybercriminals use to infected Android phone with malware. They get legitimate Android application package (APK) file and binding it with a malicious program is a relatively simple process to infect the Android phones. Most pirated or cracked apps usually contain some form of malware so we advise you not to install such apps.

What can an Android malicious app do?

The vast majority of malware on Android is focused on stealing your information, which is obviously a major concern. Perhaps the worst case scenario at the moment is malware that sends SMS messages to premium rate numbers.

Unfortunately, as we mentioned before, malware writers are employing ever more sophisticated techniques to fool you. There are apps that clone legitimate apps to fool you into downloading them and apps that are malware free when you first install them, but download malware through the update system.

As a way to make revenue, advertising companies are getting more and more aggressive by including functionality in their apps to display ads in the notification bar, adding bookmarks, or creating search engine shortcuts to the home screen. These advertising apps can also send off personal data pertaining to your device or account and will often require more permissions to access functionality of your device than the free app you downloaded requires.

The most common Android malicious apps will do at least one of the following:

• Collect and send GPS coordinates, contact lists, e-mail addresses etc. to third parties
• Send SMSs to premium-rate numbers
• Subscribe infected phones to premium services
• Record phone conversations and send them to attackers
• Take control over the infected phone
• Download other malware onto infected phones
• “Push notifications ads” delivering alerts to a phone’s notification bar – when the user swipes to pull down the notification bar from the top of the screen, an ad shows up under Notifications.
• “Icon ads” inserted onto a phone’s start screen – when the user touches the icon, it usually launches a search engine or a web service.
