I have Norton 2004 i have done everything but pull my hair out. I can not scan my computer for virus's, I get can not find NAVKRNLO error 2, could anyone tell me what this is, and why my computer can't find it? I have done everything systemtec has said to do, took it out, put it back still the same thing. I think i may have a virus now SKy something I got an email saying i did anyways, who knows that was probably the virus!
