Not impressed with Norton Internet Security 2010 at this stage. My PC was infected with Wareg51.exe and Norton didn't even detect it. There were 100's of files in my temp directory and it was slowing down my PC. Even Google had 1600 results discussing Warg51.exe when I did a search. In the end I had to use a "free" version of AVG to get rid of it. Why am I paying so much for Norton? I'm now running both apps side by side but i'm not sure that it's a wise thing to do.
