Worm:Win32/Autorun.QF is a worm - a self-propagating program that can spread itself from one computer to another. Worms may spread themselves via a variety of different channels in order to compromise new machines. Commonly, worms may spread directly by copying themselves to removable or network drives, or by attempting to exploit particular vulnerabilities on targeted machines. Worms also often attempt to spread via platforms that require user interaction in order to run. They may send themselves as an attachment to an email or an 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.

Worms may spread themselves via a variety of different channels in order to compromise new computers. Variants of Worm:Win32/Autorun usually spread using methods that include, but may not be limited to, copying themselves to removable or network drives, and placing an autorun.inf file in the root directory of each affected drive in an attempt to ensure that the worm is run when the removable drive is attached, or the network drive is visited from a remote system supporting the Autorun feature.

Worm:Win32/Autorun.gen!AED is the worm component of Backdoor:Win32/Poison.E. Variants of Worm:Win32/Autorun usually spread using methods that include, but may not be limited to, copying themselves to removable or network drives, and placing an autorun.inf file in the root directory of each affected drive in an attempt to ensure that the worm is run when the removable drive is attached, or the network drive is visited from a remote system supporting the Autorun feature.

In the wild, Worm:Win32/Autorun.gen!AED has been observed to be packaged with two components: a clean application (usually a program called "Resource Hacker") and Backdoor:Win32/Poison.E. The package containing all three components is usually created by a tool detected as Virtool:Win32/Obfuscator.C.

Windows Defender Antivirus detects and removes this threat.

This is a detection for a file, called autorun.inf, that can be used by worms when they spread to local, network, or removable drives.

The file has instructions to launch the malware automatically when the removable drive is connected to a PC with the Autorun feature turned on.

This is a common way for malware to spread. However, autorun.inf files on their own are not necessarily a sign of infection; they are also used by legitimate programs.

See our infographic to the right which shows how these worms can spread.
