What Are the Best Tools to Protect Computers From Infected USB Flash Drives?

Sometimes when sharing a file through online services is not possible, USB flash drives are the only reliable way to do so. The fact that USB flash drives do not have access to the internet does not mean they can’t get infected with viruses or malware. In this guide, readers will learn about the best tools to protect computers from infected USB flash drives. Then, readers will learn what type of threats USB security tools detect and how to know if a given USB has malware. Finally, steps on how to remove malware from a USB drive will be mentioned and whether formatting a USB drive helps with disinfection will be discussed.

USB security is about keeping USB drives clean and away from any kind of hidden malware that may not only damage the user’s machine but also any other machine the USB is plugged into. USB security tools are specialized tools that can stop the spread of malware with USB drives. The main usage of USB security tools is to scan USB drives looking for anything suspicious including, but not limited to, malware. USB security tools also keep the machines used by the USB safe.

Strong sides of The USB Program include the ability to run via the command line and protection against spyware as well as worms. From a security point of view, even though The USB Program claims to protect against viruses, spyware, and worms (the developer even has some badges to show on the official website), the fact that the software has not been updated in the past 13 years is a huge problem.

The USB Program is free to download and use. Alexey N is the owner of The USB Program. This USB security tool works by loading into the device’s memory and renaming the autorun.inf files once a user connects a removable device to the computer. To use The USB Program users only have to go to the official website, download the application, install and then launch the program. From there, the options can be accessed via the system tray menu.

An image featuring USB Threat Defender screenshot

Unique features of USB Threat Defender include proactive scan technology, definition-based scan tests, system health restoration, and multiple analysis tests. Strong points of USB Threat Defender are real-time and integrated resident shield, and a quarantine option. From a security point of view, USB Threat Defender is not good, however. This is because even though there are a lot of security features present in the software, the developers haven’t put out an updated version. This means the software will be close to useless against modern cyber threats that infected USB devices may pose.

USB Threat Defender costs $39.95 and comes with a 30-day trial period. ArzooSoft Solutions is the company behind USB Threat Defender. In terms of workings, USB Threat Defender works pretty much like any other USB Security tool – by disabling autorun.inf.

What Threats can be Detected by USB Security Tools?

The threats that can be detected by USB Security Tools are given below:

  • Trojan
  • Worms
  • Certain types of Malware
  • Spyware
  • Data leaks
  • Unauthorized access
  • Some types of viruses

How do I know if my USB has Malware?

An image featuring an USB that has malware on it concept

The simplest way to know if a USB has malware is to run a scan on the USB drive. Users can scan the USB device either via a standalone USB Security tool, several of which are mentioned in the list above, or use the USB scan component available in many modern antivirus products.

Another way to know if a USB has malware is if the USB drive registers as another device like a keyboard or a mouse or a CD-ROM. This method isn’t always guaranteed to indicate malware though. If a USB registers as anything but a USB drive, it likely has malware, however, a USB that registers as a USB may have malware. As such, this method can not be relied on in isolation.

Operating systems such as Linux provide command-line tools to monitor system logs and kernel logs which can also help identify if a given USB drive has malware. If the USB drive registers as a network device and demands full network access with UPnP servers then that is a concern.

Note:

Similarly, if a USB device asks the system for too many different drivers then that is another sign that it has malware. A USB drive without much malware should only load one driver which would help the USB drive act as a storage device.

One method of detecting malware on USB that does not require external tools is to check the saved folders on the USB drive. If the copied folder (any folder that the user may have copied on the USB for transfer) is not showing up then that is a sign there may be malware on the USB drive. Another method that does not require external tools is to right-click and open the context menu on the USB drive. If the context menu shows suspicious options such as AutoPlay or Browser then that is a sign there may be malware. If a suspicious number of files and folders on the USB device are .exe then that is also a sign of malware.

USB drives taking a long time to show up as a storage device on the user’s computer can also sometimes indicate something malicious on the USB drive.

If the USB appears to store many files with unconventional names, this may also be a sign of malware. Another simple way to get started on detecting malware on a given USB device is to try and copy some files on the USB. If the USB drive rejects copying or moving files then that is another sign there is something malicious on the USB drive.

Finally, if there are lots of shortcuts on the USB drive and relatively few actual files (only shortcuts to the files that were supposed to be present on the USB) then that is a sign a malware has transferred legitimate content into a hidden folder and replaced the files with shortcuts to malicious code.

How can I Remove a Virus from my USB?

An image featuring an USB with a virus inside of it concept

There are several ways to remove viruses from USB devices. The simplest way is to use one of the USB Security Tools mentioned above and run a scan. Another way, just like before, is to use an antivirus tool to scan the USB device or a specific content on the USB device to see if there are many viruses. The antivirus product should automatically either delete malware or put the malicious content in quarantine.

Newer versions of the Windows operating system come with the Virus and Threat Protection component which can assist users in launching a custom scan that only checks the USB Drive. This method is useful for users who do not want to use a third-party tool to perform a scan and remove a virus from a USB.

Another method is to plug the USB into the computer, run the command prompt, type the letter of the USB drive (from My Computer note down the USB drive’s letter. E.g E) into the command prompt followed by ‘:’ So if the USB drive letter is F, the user should type ‘F:’ into command prompt, press Enter, type ‘dir /w/a’, press Enter, and check for suspicious .exe and .inf files. Suspicious files will have .exe and/or .inf in front of the file names. To Disable suspicious files type ‘attrib -r-a-s-h’ and press enter. Delete the suspicious files by typing ‘del’ followed by the name of the suspicious file.

Similar methods can be used to handle other USB viruses such as the Autorun virus and Shortcut virus.

In the end, though, some of the best antivirus tools in the business can take all the complexity away from removing a virus from a USB. Hence, online users should try to use a good antivirus program to run a scan and then delete items according to the results shown.

Does Formatting a USB Remove the Virus?

An image featuring an USB ready to format concept

Yes, formatting a USB can remove the virus, but not always. Users have to make sure to perform full format rather than a quick format to make sure the virus is really gone.

With that said, the recommended way is to first use an antivirus product to run a scan on the infected USB, remove any malware found by the antivirus or USB security tool and then format the USB drive.

Keep in mind that formatting the USB drive will remove all files and folders from the USB. To format a given USB flash drive, Windows first go to My Computer, then perform a right-click on the USB drive and then select the option that says Format.

A new window should show some more options. This is where it is possible to select the File System and an option labeled Quick Format. Make sure there is no checkmark beside the Quick Format option. Clicking the OK button as the button shows up on the screen should format the USB and remove any malware/virus.
