Panda USB Vaccine, developed by Panda Security, is a free and convenient utility tool that protects your computer from malware threats spread through USB devices.
The software is designed to vaccinate USB drives, putting a stop to the auto-execution of malicious files and the transmission of infections from infected USB drives to your PC. By vaccinating your USB drives, the tool disables the auto-run process to prevent malware from taking effect automatically when the USB drive is connected to a computer. It is a preventive measure to steer clear of potential infections from spreading via USB devices.
However, it should be noted that Panda USB Vaccine is not a replacement for an extensive, total antivirus solution, and users are advised to utilize it together with other security measures for total security against all types of malware.
