sachitmaskey,

When the player is recognised as an ADFU device it will not show in Explorer as Windows is not reading it as a drive. It can not be formatted as an ADFU device.

It will not appear in Explorer until you are able to successfully load a full version firmware. Once you have managed this you should then be able to format it.
Once you have loaded the full version firmware and formatted you need to then load the correct firmware for your player.
If the 3.2.16 does not load then it is either the wrong firmware or it is corrupt and no good to you so you will have to search for another one.

If you can not get the player out of ADFU mode with any full version firmware then you will not be able to restore your player.
I doubt the problem has anything to do with a virus, just a bad firmware upgrade or hardware failure.

There are many things that can cause error reports when upgrading firmware from unrepaired or corrupt files and incorrect firmware to a poor pin connection on the memory or main chip. It is almost impossible to tell you exactly what is going wrong for you without actually having the player to test.

Whilst 'lattesurf' myself and other members can try to give you some solutions that have worked for us in the past we are not experts and they may not work on your player for many different reasons. You need to explore all possibilities or accept that perhaps your player can not be recovered.
