Ok I got a crap load of viruses and spywear within two days of getting my new computer. So I just reinstalled windows. I choose the "new install" option not the repair option. So I ran a new virus scan and adwear scan with my new version of Windows. The anti virus and anti spywear program is still detecting viruses and spywear and its detecting them in files that existed with the first Windows install but not the second. SO that tells me that Windows did not delete the old files on the hard drive when I reintalled windows. So I a going to do it myself. When I was running the Windows installer it game me the option to delete hard drive partitions. I only have one partition and its the whole hard drive. I tried to delete it but it said I could not delete the partition because it contained files required for Windows the Windows installation. So how do I reformat the whole hard drive and start from scratch?
