Perhaps when reading the title that accompanies this post, you wondered why you might need to block USB flash drives on a PC. Well keep reading, here we tell you.
If you have a computer, surely you store important personal information on it, such as work documents, school assignments, personal documentation that you have scanned and endless data that you jealously guard.
From having Windows Defender scan USB sticks automatically to removing shortcut viruses on PCs and USB sticks, nothing can get out of hand with something this delicate.
And it is that not only malware can invade your computer, but anyone with access to your PC could extract your documents with a simple USB and a little time.
In addition, when inserting the portable device, it would have the possibility of being the cause of the infection, since it has a virus. Above all, if your PC is not properly protected. It is convenient to know which are the best antiviruses for USB sticks for these cases.
In this sense, to preserve the information that we fear losing, we would be able to do almost anything. It is just at this point, where the tool that we bring today comes in. A USB port blocker.
How to get the blocker
With this tool, we will be able to limit or block USB memories on a PC so that they do not have the possibility of accessing our computer.
The instrument, which we have told you about, is the “USB Flash Block Unblock”. More specifically the job it does is disable or block USB inputs.
This blocker is portable, that is, you should not install anything on your computer. You just run the program and configure the USB ports.
But before that, you will ask yourself how do I get it? Don’t worry, you can download it directly from the internet, searching for it by name.
Likewise, you also have the option of downloading it from the “Kioskea” page, quickly and safely. What we will find at the end of the download is a compressed file, a “.zip”. We must unzip it to obtain an icon in which a USB can be seen.
The file should then be right-clicked. Now, we will go on to choose the “Run as Administrator” option.
In this way, we will see the blocker interface, this is quite simple and we will directly find what we are looking for.
Step by step to block USB sticks
Having already downloaded and decompressed the file that gives us access to this fabulous tool, we must follow the following steps.
First, run USB Flash Block Unblock. Next, we will see the program options at the same time that it shows us the status of our USB device, that is, if it is enabled or not.
We must connect the USB memory or pendrive, to be able to configure that port. If you want to check the read status of the USB input, keep the “Hardware” window open.
When inserting the USB, we will see that the icon that represents it appears in the “Devices and drives” section. We return to the blocker interface, and we will select from the options the one we want, we can block or disable. Changes are saved by pressing the blue “Floppy”.
Proceed now, to extract the USB drive that we use to customize the preferences, and so when you reinsert it you will see the changes.
For example, if you chose to disable it, when you connect a portable device to the port, you will not get the icon that allows you to access memory in the “Device” folder.
To reverse the changes, or access, you must insert the USB into the port, and from the blocker choose the option to enable it.
In order for the changes to be processed correctly, you must press the “Floppy” and remove the device. Same as you did before. As an extra note, we recommend that you do not leave the blocker’s portable file on the desktop.
If possible, store it in the safest place you can think of. Or where you think no one else would think to look. This will ensure that information is safe from undesirable people by locking USB sticks on a PC.
