Malware has been an issue for Android users for quite a while now. Thus we can see a lot of Antivirus apps in the market these days. Google has come up with an apt response to this issue, in the form of a malware scanning app codenamed ‘Bouncer’.

Here’s how Bouncer actually works:

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 behavior. We also analyze new developer accounts to help prevent malicious and repeat-offending developers from coming back.

The above states that this app scans every single app on the market. This is done automatically  through a back end process. The market  is found on their personal cloud storage systems, Thus it gets to check all the applications that exist in the market for any sort of malware.

According to Google malware reports have dropped down to 40 % in the last year .

Google has also stated the 3rd Party Antivirus apps on android always talk about viruses or malware outside the market. This includes apps you find on pirated sites, apps that exist in other “app stores”, like say the ones in China, and so on. While Google is always looking to improve Android’s security, which is already a very secure OS compared to say Windows for most of its lifecycle, but ultimately, if you decide to get an application from outside their own Market, and from an untrusted source, then there’s little blame you can put on Google for that, and you just need to be more careful with what you’re installing. Freedom to install anything you want from anywhere comes with a price – and that price must be paid in responsibility and vigilance.

Google has confirmed that Bouncer will scan for recently uploaded Trojans and suspicious files, alerting as soon as its scans pick up anything. Thus, not letting it spread in the market. Only time will tell if Google’s Bouncer is able to “Bounce” off some serious threat from any Malware or Trojan trying to get into the market.
