* SHOW V displays some important execbase pointers, which give a
  good indication of whether a virus is present in your system.
  WarmCapture, CoolCapture, ColdCapture, KickTagPtr, KickMemPtr,
  and KickCheckSum are displayed. If any of these are are NOT
  zero, then either a virus, RAD, or virus protector or some
  other program that takes control of your machine when you
  reset, is present.

eg.     show d          {have a look at the device-list}
        show Devices    {same as above}
        show t          {This is REAL MULTITASKING ! :) }
