Hi,
I purchased a new HP for my son. It came with norton security 2010 installed. We have not installed any other software. When the security software is running, web performance is very poor. I also get very long ping response with it enabled (~350ms vs ~20ms), when pinging public hosts, such as our ISP DNS servers and routers.
Is there a solution for this? From the posts, it seems to be a widespread problem.
