Step 2: After the following list opens, uncheck the choice for “Use AutoPlay for all media and devices” to stop the launch of unknown devices without any alerts. 

Method 4: Use a virtualization software

Another method that works is to download and run virtualization software. One such software is the build-in Windows Sandbox. Users can build a virtual environment on their device that carries out a simulated version of your PC on the system.

You can plug the USB device into the drive and access it through the virtual environment. In case the device is corrupted, it would not influence the network or files in the computer system.

Additional steps to take to prevent unnecessary cyber-based attacks

The possibility of getting cyberattacks is high for every user. But these are avoidable as well if you take the proper steps first. Here are some measures you can take to reduce the risk of data exposure.

  • If you connect a suspected infectious USB device to your PC, take it out immediately before downloading the software.
  • Avoid linking any USB device that you are unfamiliar with into your PC, e.g., one you found in a public spot.
  • Carry out regular scans of your USB device for malware or virus.
  • Disable the autorun feature of the device.
  • Use the latest firmware version in your system and keep it up-to-date.


Following these different steps would allow you to keep your system protected in case of harmful USB attacks. Download and use options like the Avast Anti-Virus Security for the best results.
