Currently using Norton Internet Security, Windows 7. Before I got a new pc, I had Norton 2009 and a regular system scan was scheduled weekly. When I go this new pc I installed Norton 2010 and Idle system scan was automatically scheduled. My question is do I need to schedule the full system scan regularly (if i do it will deactive the idle scan) or is the idle system scan all I need to do? The reason I ask is that i am manualy running the full scan now and it has found a bunch of cookies that apparently idle scan did not find previously. Thoughts?
