I have a Dell 9300 with 2 gib of RAM running Windons XP, SP3 and firefox 3.6 and NIS 2010 17.5.0.127.
Firefox routinely freezes while surfing and it seems like it sill un-freeze if I let the computer sit for about 3 minutes. This problem wasn't present prior to my install/ update to NIS 2010. Prior to NIS 2010 I had the most recent version of Norton AV. Sometime both the PC and firefox will freeze. Other times it is just firefox that freezes and the rest of the PC is fine.
During the freezer there is NO PC activity that is detected by the task manager.
Please help, prior to installing NIS 2010 I was very happy with Norton and my protection and it's lack of intrusion on my system. Now I'm beginning to think all the nay sayers were correct about Norton.
