Hello all, I had Norton AntiVirus on my pc but still managed to get a virus. I bought Norton 2003 and when I installed it it asked to remove the old version of norton. Fair enough I thought so I rebooted the pc and its all gone wrong. When the pc starts up I get a message saying "Windows cannot find 'C.\program File\microsoft office\office\osa.exe." This message now appears on a few programs. So I try to install Norton again but keep getting the message "cannot find E:\setup.exe! This happens on a few other programs that Im trying to reinstall.
