Microsoft 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:

Worm:Win32/Gamarue is a family of worms that belong to the Win32/Gamarue family. The Gamarue family may be distributed by exploit kits, spammed emails or other malware, and has been observed downloading other files and stealing information about your computer.

Worm variants of the Win32/Gamarue family may spread by infecting removable drives (such as USB drives or portable hard disks) that you have plugged into your computer. If you then plug those drives into another computer, the worm will infect that computer as well.

Worms automatically spread to other PCs. They can do this in a number of ways, including by copying themselves to removable drives, network folders, or spreading via email.

Typically, worms can get on your PC if you visit a compromised website, open an unsafe email attachment, or use an infected removable or network drive (like a USB flash drive).
