A hacker attacked my laptop and I was told by my ISP help desk that my email account sent out over 21,000 emails and they said I probably have a botnet or an IRC server. I want to wipe my harddrive clean and start over. I have a Dell Inspirion and this infection has rendered my pc useless. I can't do anything with it. So using the OS installation disk that came with the computer, how can I wipe my HD clean and reintsall the OS?
Thank you,
LG
