Windows Defender detects and removes this threat.
This threat is a self-propagating program that can spread itself from one computer to another. Worms may spread themselves through various channels to compromise new computers. Typically, worms may spread directly by copying themselves to removable or network drives, or by attempting to exploit particular vulnerabilities on targeted computers.
Worms also often attempt to spread through platforms that require user interaction to run. They may send themselves as an attachment to an email, instant message, or send a link to a copy of themselves in the body of a message. In these cases, the message needs to be convincing enough to encourage the victim to click on the link or attachment and run or download a copy of the worm.
