Aside from your harddrive, whether internal or otherwise, the USB drive is also easily infected by spywares and viruses.
Now you can protect your USB drive with USB Write Protect. Download it here.
Just choose USB write protection ON or OFF as shown in the screenshot below…
Hopefully after this whenever I troubleshoot or try to rid my client’s PC from malwares, I don’t have to worry about my own USB drive being infected too.
Keep it handy folks
