whenever i transfer data from my desktop or laptop to a pen-drive or USB-drive it shows like shortcuts of that folder of size 1Kb i used different pen-drives but the problem is same. i try ed AutorunExterminator, attrib -h -r -s /s /d g:\*.* and malwarebytes but the problem still there. i am using windows 7 on desktop and windows 8 on laptop.
boot into safemode with networking
run msconfig, on startup tab you will see some 3-4 alphanumeric entries seemingly random strings. disable them. (alkternatively, you can delete them completely as well. i use CCleaner for that)
run malwarebytes while on safemode
still in safemode, run the commands you typed in and delete the same 3-4 alphanumeric named folders as well as the shortcut folders
that should take care of it
