Recently I have upgraded myself from Microsoft windows XP operating system installed on my Dell Inspiron 6400 Laptop. I have also installed Norton Internet Security 2010 and updated it with the latest updates. My system was working fine. While browsing the internet last night I found that my Norton Internet Security antivirus is not working and the system performances starts to degrade. I need a solution so I need a solution so that I can troubleshoot this problem easily.
