Verdict
From 2009 Symantec has decided to make Norton consume less memory because of previous complaints by their customers and users. They made a product called Norton Netbook Edition which has all of the features of the existing one but consumes less memory. But, it went on disrupt as most of their customers would like to use it in any other pc because of its fast performance.
They didn’t continue Norton Netbook Edition after 2010 but they made their existing product with fast performance and less memory use. Norton 2011 went on very fast performable antivirus with less memory consuming capability along with its continuing feature of worlds most trusted and secure internet security and antivirus software. It consumes more less memory when you minimize during scan with same quick speed of scanning.
NIS 2012 got more feature that can boost up your computer or pc. IT has got startup manager (can be accessed clicking on performance) that can block startup programs which occupies your computer memory and CPU. This feature of Norton is something special than any other utility software or windows msconfig startup tool. When you block any program using Norton 2012 startup manager there is no way it can get it auto start unless u allow it from Norton while most of other utility software cannot hold them up including windows msconfig and more it won’t affect any other program or windows.
