Thread: reformatting or removing all memory from a computer with no dvd or cd rom?

I have an intel class mate (a small net book with no dvd rom. and it has a virus. i would like to re format it but there is no dvd to do that with or if there was there is no rom

that means it most likely has its own hidden recovery partition to restore the computer back to new you just have to pay attention to certain buttons when you try to restart the computer! or maybe go to System restore and it has the option for full factory recovery from there!
