Report A simple and effective anti-virus in Privacy and Security Posted September 16, 2010 Hi there MR.GROOVE I think that NOD 32 is very simple and Effective Anti virus and Spy ware program it for everyone but I Agree about MSE its the same as NOD 32 does the same job and stuff like that:) I agree with this guy. Nod32 is probably the best PAID software. Microsoft Security Essentials is the best FREE software. I still haven't had a need for an anti-virus, just gotta use common sense. It is nice knowing that something is there to catch me though if I do slip up.
