If you think that you have a virus on your Amiga, then you have to start an antivirus program from a clean scource. That means you have to boot your Amiga from a floppy disk. Virus Help Team have made a floppy disk with VirusZ III that you can download, with the latest version of VirusZ III and the support library the program need, and they are all clean and ready to use, this floppy disk are packed with 'Amiga Disk File' (adf), so you have to unpack the archives first.

VirusZ is the last one of the classic antivirus programs for Amiga computers that still gets updated (from time to time). This is the first version that works on classic AmigaOS, MorphOS, AROS and AmigaOS 4.x, but due to some limitations it's still a beta-release.
