Short Bio

This is the generic detection for a worm with Autorun capabilities. Variants of this worm create an icon for their executable that looked exactly like a folder icon.


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


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.
