SecureMyUSB

The thing with working in an environment that exposes your computer to other individuals is that they can simply conduct harmful actions towards you by simply plugging in a USB flash drive full of malware or even steal information from you. One way to make sure that nobody can interfere with your PC through the USB ports is to employ the use of SecureMyUSB, a simple tool able to render USB ports useless.

The application doesn't offer too much, from a visual standpoint, but the aesthetics are not really of importance with this tool, as the effects are the ones that matter here.

SecureMyUSB can be quickly launched right after unzipping the archive. Having no installation process is a great feature for users who manage multiple computers and wish to have the possibility to lock USB ports right in their pockets.

SecureMyUSB can be used to simply restrict the USB write access, which means that nobody can copy stuff from your computer to their USB drives. To activate this option, check the first box.

The second box activates a much stronger feature. Completely disable the USB device in order to prevent anyone to install malware on your PC. Disabling the USB will hide any connected USBs, so their contents cannot be accessed. However, having both boxes checked should ensure the maximum levels of protection.

SecureMyUSB can be used to ensure your machine's security in a non-safe environment. However, one of the easiest ways to restrict access to your computer is to lock the screen when you leave it and protect it with a strong password. Still, if this method is not enough for you, SecureMyUSB can add the extra layer of protection you require.
