In response to the My experience with Norton 2009
Absolutely terrible.
It practically locks you out of your own computer. I have but one account and that one account is the sole administrator account. I cant save changes in msconfig, I cant micromanage system processes and I am now locked out to older 'my documents' subfolders. I'm getting, "Must be and administrator or have admin access".
Flexibility? Optimization? Forget about it. No matter how you tweak it, the core norton processes dominate your task manager, peaking at the high 80-90s cpu usaged irrespective of CPU speed, strength or max RAM capacities, while supposedly 'disabled' for 30 minutes. In the event your web browsing and programs are rendered totally unusuable.. Guess what? Good ol Norton saw it fit to make their product and their processes tamper proof.
Forget the days of Ctrl+Alt+Del to close out that old resource hog in task manager, with this product, you forfeit control, micromanagement and distribution of system resources on every level.
Shall we get on the subject of cpu heavy programs, online games and applications? Take World of Warcraft for example... As a poster stated before, you don't want to be in a situation where you make a full of yourself because you drop to 1fps in a raid.
With this program, you WILL drop to 1fps on a raid pull and make a fool of yourself.. And consequently piss of alot of E-Friends.
Do you get security? YES, at the price of a completely unusable computer that has 'securely' locked you out of it!
Just look up the statistics for the Norton Antivirus I/O File delay. It is recording breaking.
Avoid!!
