I work at a small company and I try and help with our computer when I can. We found out that we have the so big virus on one computer. (using 98) I tried to purchase and download the newest virus version, but it never would take. The directions said I needed to uninstall the old version. I did and then tried to run regedit to make sure I didn't have to manually remove NAV. When I tried to run it, it said there was a memory problem. What is that? Also, when I tried to use the removal tool for "so big" it said it couldn't find it to remove it. I followed the instructions. The only thing I wasn't sure about was if all of my programs were turned off that runs in the background. I figure that NAV site was right and so now what do I do. We finally ordered the disk from NAV and said goodbye to the download. I will try and work with the physical disk and hope it works. So right now, we have no AV on that computer. Any hope for me?
