I have a laptop that won't boot up. It gets me as far as xp screen but no desk top. I do an ctrl, alt delete and find that the process "explorer.exe administartor " is useing anywhere from 67% to 99% of my cpu usage. Because it's the explorer.exe process if I shut it down of course I won't be able to get to the desk top. The person who owns this laptop said that Nortons discovered a trogan before all of this started happening. Any ideas how I can get into this system so that I can run a virus check? Thanks
