Peter, Norton just stays at let say 13405 files scanned and it would not move, sometimes is more files sometimes is less, I only managed to do it once with the Norton antivirus that came with System works but after that I have been unsucessful with both versions of Antivirus ( The one with system works and the one with the firewall) The funny thing is that I have been able to do it with the free online scan called Housecall from the makers of Penicillin. They were the ones that detected the viruses. One more thing when I cancel my scan my cpu keeps working at 100% even if I ctrl-alt-delete and end task; I need to reboot.
