Why Kasper Sky and Nod 32 are best in this poll?

no idea..coz they're famous?n perform well as well
because i only use free software.for antivirus i use MSE..for spyware protection i use superantispyware and yes..both r free..
LAst week my 2nd laptop which had norton installed got infected by the .scr virus.Turns all of your files invisible and creating a duplicate with screeensaver file (.scr) instead..although i scanned the pendrive.Norton did't detect it but MSE did..hehe..did;t say norton (or any other non-free av's r not good),but i prefer MSE,dont know why..chill

 

Nod32 is the least heavy av I used and less false positives. Kaspersky is good but if you use a lot of hacks there will be a lot of pop ups like hacktool detected and more nags. They are both well supported and are good, if you are on a budget kaspersky is good because nod32 cost like 50$ last time I checked.

 

Kaspersky and NOD32 have the best scanning engines.

NOD32 excels in system performance as you don't even feel there is an Antivirus on your system but it is actually very very secure, I have been using it for the past 6 years and never got a virus and yet enjoyed top notch performance!

I suggest you try the demo after uninstalling your current antivirus. Itll work just as good as the full version for 30 days. then youll know for yourself why NOD32 gets so high of a rating in polls

 

I've tried AVG and Avira and they both seem a bit heavier on resources then say my NOD32 SS. But if you don't mind a little slow down then there both good alternatives w/o having to pay for it.

 

The only free antivirus I would use is Avira AntiVir, however, I don't because it's a bit heavier on the resources thatn NOD32 is, it is however the best out of the FREE antivirus alternatives. But for paid, NOD32 demolishes the competition with the best performance, you don't even feel that you have an antivirus program running, it's that light! yet still very very secure! never had a single virus in 6 years!
