Added to the Dr.Web virus database: 2015-11-19

Virus description added:



Once a program containing Android.DownLoader.244.origin is launched, the Trojan prompts the user to enable the malicious accessibility service. If the victim follows the instructions and enables the corresponding accessibility service, the malicious program becomes able to monitor all system events and install various applications specified by cybercriminals on behalf of the user and without their consent.

screen Android.DownLoader.244.origin #drweb

After that, the Trojan tries to get root privileges in order to download and install different programs into a system folder upon a command from the command and control server.

Curing recommendations


  1. If the mobile device is operating normally, download and install Dr.Web for Android Light. Run a full system scan and follow recommendations to neutralize the detected threats.
  2. If the mobile device has been locked by Android.Locker ransomware (the message on the screen tells you that you have broken some law or demands a set ransom amount; or you will see some other announcement that prevents you from using the handheld normally), do the following:
    • Load your smartphone or tablet in the safe mode (depending on the operating system version and specifications of the particular mobile device involved, this procedure can be performed in various ways; seek clarification from the user guide that was shipped with the device, or contact its manufacturer);
    • Once you have activated safe mode, install the Dr.Web для Android Light onto the infected handheld and run a full scan of the system; follow the steps recommended for neutralizing the threats that have been detected;
    • Switch off your device and turn it on as normal.
