A Trojan implemented as a dynamic-link library. There are two modifications of this malicious program—for 32-bit and 64-bit Windows versions. The Trojan is installed on the system by means of a dropper implemented as an executable file. The dropper decrypts the library saving it under a random name into %windir%\System32\%random%.dll and recording it as AppInit_DLLs in the system registry.
The library is injected into browser processes and into explorer.exe and svchost.exe if svchost.exe is run with the "-k netsvcs" parameter.
The Trojan can perform the following actions: download and launch executable files, intercept browser network functions, launch browsers without user knowledge, generate traffic for certain webpages, update itself, communicate with a remote command and control center.
If the operating system (OS) can be loaded (either normally or in safe mode), download Dr.Web Security Space and run a full scan of your computer and removable media you use. More about Dr.Web Security Space.
If you cannot boot the OS, change the BIOS settings to boot your system from a CD or USB drive. Download the image of the emergency system repair disk Dr.Web® LiveDisk , mount it on a USB drive or burn it to a CD/DVD. After booting up with this media, run a full scan and cure all the detected threats.
If the mobile device is operating normally, download and install Dr.Web for Android. Run a full system scan and follow recommendations to neutralize the detected threats.
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 for Android onto the infected handheld and run a full scan of the system; follow the steps recommended for neutralizing the threats that have been detected;
