At the moment, flash drives are the main way to transport data. To copy files, users connect their flash drives to dozens of different computers every day. It is not surprising that malware developers often use flash drives to spread malware.
By connecting your USB flash drive to a computer infected with viruses, you will instantly become a victim of a virus attack. A virus is copied to the USB flash drive, and your files are modified. In most such cases, after a flash drive is infected with a virus, the following picture is observed: files are not visible on the flash drive, it seems that the disk is completely empty. But, when checking the occupied space, it turns out that the files are taking up free space on the disk. Accordingly, nothing has been deleted, you just do not have access to the files. In this article, we will show you how to solve this problem.
Step # 1. Check for antivirus.
If no files are visible on the flash drive, it means that it is infected with viruses. Therefore, you should not connect it to all computers in a row, hoping that on one of the computers your files will become available. This way you are only spreading the virus, and doing a good service to the virus writer.
You can connect an infected USB flash drive only to those computers that are protected by antivirus. Before connecting the flash drive, you need to make sure that the antivirus is up and running. Computers with disabled or unloaded antivirus will also fall victim to infection.
Step # 2. Checking the flash drive for viruses.
After connecting the flash drive, the first thing to do is to perform a full scan of the flash drive for viruses. To do this, open “My Computer”, right-click on the USB flash drive and run a virus scan.
Step # 3. Enable display of hidden files.
After the virus check is completed, you can work with the flash drive. If files are not visible on the flash drive, this means that they are hidden. To view hidden files, you need to enable the corresponding function.
To do this, in any window, hold down the Alt key and open the “Tools – Folder Options” menu.
In the window that opens, go to the “View” tab. Here you need to uncheck the box next to the item “Hide protected system files” and check the box next to ” Show hidden files, folders and drives.”
Step # 4. Viewing hidden files on the USB flash drive.
After these steps, you need to open the USB flash drive again. Now you can see hidden files and folders . Hidden files and folders are displayed with semi-transparent icons, making them easy to distinguish from regular files and folders.
In order to turn hidden files and folders into normal ones, it is enough to call the object properties and uncheck the box next to the “Hidden” item.
