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.
