Remove Net-Worm.Win32.Kido on XP

Hi anyone

I am new of Comodo Forum but I would like to know if I can get some help to remove Net-Worm.Win32.Kido.
I tried many thinghs but virus still inside my pc, even after format hard disk and reinstaller XP SP3.
I removed all autorun, I run “Net-Worm.Win32.Kido removing tool, Kaspersky Lab 2010 version 3.4.14 Mar 19 2010 10:17:17” but after all, Comodo tell me still having virus.
May be the Kaspersky Utility is an old version or the virus I got is a variant.

Any suggestion how to solve it?

Thank you in advance, have nice day.

Can you upload the file being detected to and post the link here
