We previously reported you that Android got infected by some malicious apps. The function of those Malwares was to give the data of the user remotely to the hackers. Google removed the malicious applications from Android Market within a few minutes of being notified, but has otherwise remained silent on the situation. Google has now confirmed that 58 malicious applications were uploaded to Android Market, and that they were downloaded onto around 260,000 devices before Google removed the apps Tuesday evening.

For those who got affected and are affected, Google from tonight will enable the “Remote Kill Switch”  function that allows it to remove these malicious applications from any affected Android devices with no action required from the user. Google will also be issuing a fully automated Android Market security update to infected devices that should remove the root kit (again, no user action will be required). All affected users will be receiving email notifications about the situation as well.

Google says that it’s taking steps to try to prevent similar malicious apps from making it onto Android Market. But it’s being vague on the details:

We are adding a number of measures to help prevent additional malicious applications using similar exploits from being distributed through Android Market and are working with our partners to provide the fix for the underlying security issues.

Google also have sent and Email to the infected people. You can review it below:

You are receiving this message to inform you of a critical issue affecting your Android Market account.

Hello,

We recently discovered applications on Android Market that were designed to harm devices. These malicious applications (“malware”) have been removed from Android Market, and the corresponding developer accounts have been closed.

According to our records, you have downloaded one or more of these applications. This malware was designed to allow an unauthorized third-party to access your device without your knowledge. As far as we can determine, the only information obtained was device-specific (IMEI/IMSI, unique codes which are used to identify mobile devices, and the version of Android running on your device).

However, this malware could leave your device and personal information at risk, so we are pushing an Android Market security update to your device to remove this malware. Over the next few hours, you will receive a notification on your device that says “Android Market Security Tool March 2011” has been installed. You are not required to take any action from there, the update will automatically run. You may also receive notification(s) on your device that an application has been removed. Within 24 hours of receiving the update, you will receive a second email confirming its success.

To ensure this update is run quickly, please make sure that your device is turned on and has a strong network connection.

For more details, please visit the Android Market Help Center.

Regards,
The Android Market Team
