It is recommended to ensure system security when a large number of viruses are transmitted through a USB flash drive.

Recently, viruses spread through USB flash drives. It is reported that the "U disk parasite" virus ranked first in the virus rankings this week, becoming one of the major threats to the Internet. Another widely spread virus, "random 8-digit", is also spread through a USB flash drive this week.

(You can also use the WINDOWS "group policy function" by running gpedit in the "run" box of the "Start" menu. run the msc command to find the "manage template" function under "Computer Configuration" and "user configuration" in "group policy, open the "Disable automatic playback" setting in the "System" menu, select "enabled" in its properties, select "All Drives", and then click "OK" to save the settings .)

2. Do not use double-click to open the USB flash drive. Instead, right-click and choose --> open.

3. When you use a USB flash drive to store and copy data files, enable the "Real-time Monitoring" function of anti-virus software in the computer system to avoid Virus File intrusion and infection.

4. Open the "Hide protected operating system files" option in the "folder" option and select the "show all files and folders" option so that the virus can be detected immediately after the USB flash drive is infected.
