Summary

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.

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