Edit your boards.txt to create an entry for programming your Arduino with the AVR-ISP.  Then use that to program the Arduino.  It should automatically overwrite the bootloader.

not clear.
what sketch should we program using AVR-ISP in order to overwrite, the bootloader with other necessary program.
can we re-virgin our chip.

You just program the "other necessary program", which by now, presumably, you've written.

why AVR-ISP supports our micro controller using ARDUINO software?
and why bootloader dosent over-write when we burn using FTDI chip?

The bootloader is what is communicating with the FTDI - it takes images and writes them to the lower part of the flash memory.
When you use ICSP, you are bypassing the bootloader.
It is how the bootloader got there in the first place.

It would help if you wrote full sentences for questions and stopped the auto-repeat on your punctuation keys.
