Which Anti Virus is the best one?

I use Windows Defender in Vista because it's built in, so it works faster than others with real-time protection activated.
And no AV

 

How much of a slow down does Kaspersky cause the system?

 

Kaspersky for me

 

I'm really happy with latest version Kaspersky 2009...its using least system resources on my machine and running quite smoothly

 

well subtract my vote for Zonealarm Pro...I'm going to ditch it net year when my subscription runs out...too many idiosyncrasies. I've had issues on both machines it is installed on

 

Kaspersky Lab and Nod32

 

The free one by AVG is great, and running it along side a outdated version of Norton is always good. =P

 

I use avast (free version)
AVG Free is also a good one

 

Norton will be the best one I used it and trust it with all of my information

 

Norton...for the same people that think IE > FF

 

I use Nod32, & think it's great.

 

NOD32 ftw for sure!

 

I just installed the new AVG to see what it's like and I think it's awful.
I'll be heading back to AntiVir soon, it's still the best by miles.

And as for Norton, don't get me started on that pile of crap...

 

i think panda antivirus is the best. i made some tests with some keyloggers and most of the avs didn`t recognise the infected files. i even tested with norton full update and found nothing. the only ones that discovered the files were panda and mcaffe but the last one has to be updated to do this.

the bad thing is that panda is using to much resources. i`ve tested on a 2 Gb ram pc and 3Ghz proccesor and it really slows down the pc.

 

Kapersky for me.. Much better than nortan

 

I'm using Comodo antivirus which is free and pretty good. They have a free firewall as well as backup, anti-malware, etc... Check it out ->http://www.comodo.com

 

Currently using AVG. My web pages are loading slower..

 

its all about Kaspersky

 

Just bought Kaspersky - it seemed to have the best reviews - so far so good - I like it

I ran into some issues with McAfee - did not have a great experience with them -

 

I was with the opinion that Kaspersky is slowing down my computer in the past (and it really was slowing it, but I had only 128 RAM and 1Ghz processor power back then), so I was using Nod32, but after I bought my new computer and switched to Kaspersky I was reborned. It is so much more effective than the others and so light (with my current configuration).

Really, it doesn't even slow my computer a little, while providing the perfect professional protection I need...
