I had the 2007 Norton-Anti Virus product installed on my computer and wanted the Norton technicians to install my 2008 version but apparently it seemed that my 2007 version subscription was renewed, when the Norton technician, who took control of my computer had attemtpted to install the 2008 version, and after the technician registered my product, she began the live update process, which is done after the installation process is completed. Unfortunately, after the technician pressed on the live update button to download the latest updates, she accidentally pressed on the cancel button on the live update box. She then, went into the task manager program to see what processes were still running and while doing this, my computer suddenly shut down and I was getting a message from Windows that the operating system could not be found. After that happen, for several hours, of trying to restart my computer, windows xp was able to start up in a normal fashion. The next day, I contacted the Norton technician and asked him to uninstall the 2007 version and reinstall the 2008 Norton product. He said would not install the 2008 norton product but instead he would run the live update download process again and after awhile, when the norton updates would not download, he press the cancel button and when he did a message appeared from Windows that said that canceling now might damage the operating system but the technician press the yes button and while doing this he decided to download the norton 2008 product from their website. When the download process was 95 % complete my computer went down again. I would like to add that I have the free firewall version of Zone Alarm that is installed on my computer and I asked both technicians if I should uninstall the Zone Alarm product before they install the Norton product and they both said it was not necessary. I have tried repeatedly to restart my windows xp but have received the message on my computer: Windows could not start because of an error in the software. Please report this problem as: load need DLLS for Kernel and also received this message: Invalid boot. INI file. I appreciate any suggestions you have regarding this problem with my computer.
