Have used this product since year 2012 in Desktop PC and Laptop its good working well, My personal experience is that when you have this software it does not make your system slow down.So the performance becomes quick of your system.This Antivirus directly deletes the infected files, while other software repair it. It has good feature of boost speed.One who needs good performance of system should go for Net Protector, for who performance has less importance can go for another Antivirus.
