Nod32 uses 90% of the CPU?

I'm using bit defender from long time there is a slight change in my system performance...it doesn't affect me so much.....once try this one also.....

Bit defender slowed down my pc drastically. Nod32 has given me no problems haven't tried avast yet but will give a try

nod32 3 version is using system resources more than the 2.7 version ..i think ..bit defender is also gud ..espcially Total security one ..!:D

I got sick of nod32 and started using kaparsky.

if your PC specs aren't too good that could be a reason why but I kinda doubt it, also have you tried re-installing it to see what happens? Or maybe try the older v.'s

nod 32 is the best make sure you use the last version of v2 and not 3 cuz version 3 is different and bloated and version 2 still updates...
