The reason the virus can spread via USB is that the virus copies itself onto the USB drive and then creates a hidden file called autorun.inf to enable the drive's Autoplay feature.

And once you click to open the USB, it accidentally activated this virus. And there is a pretty good way that I used to apply it often is to create an autorun.inf file available in the usb, the purpose is to prevent the virus from overwriting its autorun file.

But now the virus has many smarter types, so I don't use this method anymore. Instead there are the following very good ways:

1. Turn off Auto Play

Implementation: By default, when you plug an external device in, for example USB, removable hard drive, CD / DVD ., the computer will automatically turn on.

To turn off this function we go to Control Panel => AutoPlay then uncheck the box 'Use Autoplay for all media and devices'.

To solve this problem is quite simple, if you want to run * .exe file, use Winrar to  compress the file  as .rar or zip.
