Before using a USB flash drive that is newly purchased or given by others, it is recommended to conduct a full scan with the anti-virus software on your computer. There are many excellent anti-virus software on the market, such as the latest versions of Kaspersky and Bitdefender, which can effectively detect and remove viruses that may be present in USB flash drives.

In addition, you can also consider using online virus scanning websites, such as VirusTotal, etc., to upload suspicious files in the USB flash drive for detection.

3. Develop a good habit of ejecting the USB flash drive

After using the USB flash drive, develop the habit of safely ejecting it. Directly pulling out the USB flash drive may not only damage the USB flash drive, but may also cause viruses to invade. For Windows systems, you can find the "Safely Remove Hardware and Eject Media" option on the taskbar; for macOS systems, you can eject the USB drive in Finder.

After enabling write protection, the USB flash drive can only be read but not written, which can prevent viruses from infecting the USB flash drive. However, write protection also means that new files cannot be saved to the USB flash drive, and you need to decide whether to enable it based on the actual situation.
