Threat expert Report: Sets the drive to autoplay by creating autorun.inf file in its root directory. If the drive is shared across the network then other remote computers can be infected any time they try to access this share.
Creates an executable file in the fake Recycle Bin folder with the purpose of concealing its presence in the system.
Removal:
Boot into safe mode.
Show hidden file.
Delete Autorun.inf from each drive and recycled folder
