i was just  wondering... for windows computers there are some ways an anti virus can protect the computer from hardware exposure fom other devices like on usb. These popups would ask the user to scan the usb first. and i dont know if AVG has this? But i also learned that when the screen is locked the usb's still can install harware, and this way could breach the security by running an automated script. Does AVG has something for it? and on which parts parts of it does AVG protect me? I would like to learn something about this
