Hi there
we're having problems with our office computers being infected by one (ore more) s copying themsleve(s) to our usb thumbdrives. They create executables named like folders originally on the drives (and settingg the original ones to "inivisible") AND/OR creating a "notepad.exe", both of which having a "folder" symbol, not the "executable" symbol.

kaspersky online scanner defined them as

win32.agent.something
and
win32.VB.something

SpybotS&D does not recognize them, Symantec anti Virus recognizes them but can't get rid of them. I tried to delete them by hand, then, I ran malwarebytes anti-malware , it sez:
