On an IBM compatible type of PC (i386, i486 Pentium etc etc) running Windows
(any version) or DOS (any version) there is no way to infect it with a virus
just by 'putting it in the drive' without any other action.

You need to execute a virus in order for it to infect your computer. Just
putting a disk into a drive on a normal PC will not cause any data on the
disk to be executed. You need to boot from it or execute it or almost
anything else - but simply putting it into a drive can't hurt anyone.

Or have a look at the Nashsoft Anti Virus Research Center and tell me which
type of virus you believe you have so I can find out more about this
extraordinary feat.

If you find that putting it into your drive causes a warning message from
your anti-virus software to appear then clearly your anti-virus software is
running in background and noticed the hardware notify the system of a
disk-change and decided to do a bit of pre-emptive scanning of it's own.
