Worm.Autorun

Short Bio

Worm.Autorun is a worm that spreads by altering the autorun.inf file on removable media, such as USB drives, in order to infect every system they are connected to.

Remediation

Malwarebytes can remove this worm without further user interaction, but you may want to format any infected drives before using them again. Be careful with the executable files that you decide to keep as they could be the “infector”.

Avoidance

Microsoft has set AutoRun to “off” by default to mitigate the impact of this worm. So be warned if you change that setting. Also, AutoPlay is a similar feature that can be abused more or less in the same way.

Associated threats

  • Worm.AutoRun.CF
