USB Guardian (USB Guardian.exe). USB Guardian prevents autorun viruses on USB drives from running.
USB Guardian keeps your PC safe by blocking malware, worms, and viruses that often spread through portable drives. This lightweight USB security protection software runs silently in the System Tray and monitors every connected device in real time, offering fast threat detection and safer plug-and-play use.
With automatic autorun blocking, USB Guardian prevents harmful programs from launching the moment a drive is plugged in. You can keep CD-ROM autorun enabled while still protecting your system. Designed as an easy-to-use real-time malware removal tool, it scans each USB device, locks suspicious files, and lets you delete or manually unlock items once verified safe.
Although the interface is simple, everyday protection is effortless—USB Guardian works independently with minimal interaction, while still giving you instant access through the System Tray. It offers solid PC virus protection for USB devices, though its installer includes optional browser toolbar changes that users should review before proceeding.
