I have been using MSE + Comodo Firewall, and I haven't got a single virus yet.

Up until these year i would agree with you but the new Norton programs run pretty light. I had stopped using them for that exact reason then i think they realized that their program was a resource hog and they were losing customers.
Free:
Microsoft Security Essentials
Paid:
Norton Internet Security or 360 (anything 2011 onward).
i need a new youtube to mp3 converter cuz dvdvideosoft isnt working for me anymore any suggestions?
Malwarebytes should be added to the anti-Virus List.
