On Thrusday Google Revealing a service, codenamed “Bouncer”, to automatic scanning of malicious application to protect users. So the Bouncer scan all new apps as the time when developers load them onto Market and approve only them when they are malware free. The service performs a set of analyses on new applications, applications already in Android Market, and developer accounts.
So Here is How Bouncer Works according to Google,
” once an application is uploaded, the service immediately starts analyzing it for known malware, spyware and trojans. It also looks for behaviors that indicate an application might be misbehaving, and compares it against previously analyzed apps to detect possible red flags. We actually run every application on Google’s cloud infrastructure and simulate how it will run on an Android device to look for hidden, malicious behaviour. We also analyze new developer accounts to help prevent malicious and repeat-offending developers from coming back. ”
Google said that the number of downloads of potentially malicious apps dropped 40% between the first and second half of 2011.
“While it’s not possible to prevent bad people from building malware, the most important measurement is whether those bad applications are being installed from Android Market – and we know the rate is declining significantly”, Said Hiroshi Lockheimer, VP of Engineering, Android.
They also disclosed other security features to make mobile malware less disruptive, like “Sandboxing” technique to put virtual walls between applications and other software on the device. So, if you download a malicious application, it can’t access data on other parts of your phone and its potential harm is drastically limited.
Android provides a permission system to help you understand the capabilities of the apps you install, and manage your own preferences. That way, if you see a game unnecessarily requests permission to send SMS, for example, you don’t need to install it.
and If you Installed a malicious apps then you can easily removed it from your device and if you are not able then Android Market also has the capability of remotely removing malware from your phone or tablet
