I wish to reformat my computer. I have alot of spyware due to friends and family -_- and I cannot get rid of it with any programs I have tried. So I decided it would be best to start with a clean slate and keep them off of my pc. I have windows xp pro installed right now and I want to reformat with windows xp pro again. How would I go about doing this? And also is it a good thing to do?
