What’s different about the Portable Edition?
It’s the same Trojan Killer, packaged to run directly from a USB drive—no installation needed on the PC. It’s ideal for locked-down or heavily infected machines where installing software is difficult.
Your activation info and settings are stored on the USB so you get a consistent setup across PCs. For safety, Trojan Killer does not use quarantine on the USB; detected items are cleaned on the host machine and are not copied to your stick.
