分析不法分子使用的技术可以使我们预测其可能的发展方向，以便更加有效地抵御今后可能遇到的威胁。您也可以了解一下恶意程序如何在被感染的系统中运行以及如何抵御这些程序。
Android.Locker.6 in virus library:
A family of ransomware Trojans for Android.
Different modifications of these malicious programs can lock the device displaying a warning about some violation of law. To unlock the device, the user has to pay a ransom. If the user attempts to close the warning message or to exit to main menu, the message reappears preventing the user from operating the device in a usual way.
More dangerous modifications of Android.Locker run a search for user files stored on an SD card (for example, graphics files with .jpeg, .jpg, .png, .bmp, .gif extensions, text files with .pdf, .doc, .docx, .txt extensions, video files with avi, .mkv, .3gp extensions) and encrypt them. Then Trojans demand a ransom to unlock these files.
If you have encountered the first modification of these Trojans, it is recommended to reboot the device in safe mode (see User Manual) and to remove the malware manually or using Dr.Web for Android.
