I think Kaspersky is better. Maybe NOD32 works faster then KAV but it is not safe. I am working in Internet cafe and there have 50 computers. When i formatted my computers and first installed nod32 after few days they fails one by one no matter how i care od them. And then i have to format them again and again. So i started use KAV7. Now I have no problems. Sometimes one or two pc's fails but i have lot of free time now. So I recommend you use KAV7 or maybe KAV8. I hear that they released KAV2009 it mus be great. SO if guys can find KAV2009 key please send me(emusicsr@yahoo.com).
