Guardian 1.1 was a freely distributable antivirus bootstrap for Kickstart 1.2 (33.180) developed by Leonardo Fei. It came in two forms, a program that installs itself in place of the bootstrap module, and a program that installs Guardian 1.1r into the Kickstart disk directly (replacing the Debug() function). The Guardian 1.1 distribution is available on Fish disk 154 and has also been made available locally for download here.
