One of the concerns Android users have had with their phones over the last couple years is security. Most notably, Android has had some problems with malware in their app store.

But according to MSNBC, there’s good evidence that Google is working on a malware scanner for the Play Store (Android’s version of the app store, which used to be called the Android Market).

While there have been anti-malware apps for Android out for a while now (I had one on mine when I had an Android), the apps were third-party.

Now it looks as though Google will be adding malware-scanning software into the Google Play app, if the source code “doesn’t lie,” as one analyst put it.

According to AndroidPolice, there’s evidence in the source code of a new app that will serve as a malware scanner.

This would make sense, following Google’s recent acquisition of VirusTotal, an online malware and virus scanner. And with Google working on their new operating system, which rumors say will be named “Key Lime Pie,” Android users could be looking at inclusion of the app in the next operation system upgrade.

According to the code…

“There is something call ‘App Check’ that will allow Google to inspect every app you’ve already downloaded,” wrote AndroidPolice’s Amadeo in a blog post. “And a doorman-style app blocker that will warn you if an app is suspicious. It also sounds like they will have a ‘shut up and download it’ button, for people that like to live on the edge.”

In any case, I’m sure it’s something Android users look forward to. No one likes to have to ‘factory reset’ their phone.
