Summary

Windows Defender Antivirus detects and removes this threat.

This malware family can give a malicious hacker control of your PC. The malware can also steal your sensitive information and change your PC security settings.

We've seen them installed by exploit kits and other malware. They can also be attached to spam emails.

Some variants of this family are worms and can spread by infecting removable drives (such as USB flash drives or portable hard disks). If you plug those drives into another PC, the worm will infect that PC as well. See Worm:Win32/Gamarue for more information.

On November 29, 2017, law enforcement agencies, in cooperation with Microsoft Digital Crimes Unit and with help from Windows Defender researchers, disrupted the Gamarue (also known as Andromeda). For more information:
