malmo virus

I have malmo virus in my computer and I have tried to remove it using the option I read in your response to one of the members’ question i.e starting the computer with windows xp disc and typing “fixboot” on the prompt but after all this, the virus is there. What should I do now. I have three operating systems: Windows XP, Windows 200 and windows 98. Please help.
