I know it is obvious but perhaps the Workbench disk is infected.  I
suggest you write protect your originals, boot, and then make new
copies of kickstart and workbench.  Then get ahold of a good virus
check program and go through your disks.  Also you can try doing
a hex dump of the boot block and checking it against the C/A boot
block.  A boot block virus will have extra code before the jump.
It may also jump to a different address.
