Well, NOD 32 i think whit my personal expierience has been the most effective tool against all kind of virus troyans malware and stuff, it will not bother you whit a lot of pop up screens while you are surfing on the net and it will have your system running smoothly.. somebody from down here says kapersky doesn't use too many resources, when i try to use kapersky hundred of pop up has fill up my screen and make you think is catching virus troyans and malware as you are in a minefield and of course loading your resources to the maximum.Dont believe what magazine says cause they get pay for those advertise...its just that... get your own expierence trying every single tool the you can have access to it and you will find was fit best for you.a
Good luck!!
