what is the most effective anti virus,

for me the kaspersky anti virus because it cant detect a worm virus that spread to your computer

I have McAfee, myself, and there is one virus that can't be completely removed. I can't ever remember the name of it. Next time I will write it down and let youall know what it is. Maybe somebody can tell me what I can do. I scan my computer everyday, sometimes several times a day. McAfee does remove most of my viruses it seems. Kathy.

I use ESET NOD32 Antivirus. so far it is the best and effective antivirus.

Hi, I am using AVG 8 free version. I think Kaspersky is a good choice. I have tried it before and it is excellence but I fell it is over sensitive some of the time, it block almost all suspisious activity, but sometime it just delete something that you don't think it contain virus. My PC in my hometown is running on ESET NOD32, but don't really know much about it. I think McAfee is as good as AVG, both managed to detect and delete most dangerous item, but AVG won't remove any tracking cookies automatically, it just place it under warning. Lastly, I won't use Norton at all as I think it is almost useless. There are some other antivirus, but I am not too sure about its performance. I am also rely on Window Defender for protection.

use Kaspersky Internet Security 2009...a way much better if you scan in safemode..=]
