Which is your favorite?

 

My personal preference are - Kaspersky Internet Security + Sunbelt CounterSpy for real time protection. I have also used Spybot S&D and MalwareBytes for on-demand scan.

 

For me Kaspersky is best for pc/internet security.

 

Kaspersky is one of the best (top 2-3), I love it, but for servers it's a real overload.

 

I like mcafee for paid avg for free

 

Kapersky is the best .
Avira and other avs too many false virus it will make my files auto delete.

 

I have used kapersky before, and know its powerful function,but it takes too much source of CPU , so I changed it .

 

There is no one suit me, I like let my computer in the risk

 

KIS 2010 anytime.. with their powerful.... realtime scan system

 

I use NOD32 in my opinion is the best and it use little resources.

 

I use NOD32 and sometimes install Kapersky to check my system

 

Right now im using AVG. Why because I got a license key for cheap, no other reason. I used Kaspersky before and would recommend it to everyone however to this day Avira is my favourite, best of all? it's free!

 

The second last one Mcafee. I like its simple design and effective performance.

 

I like AVG, avast and avira. McAfee and NOD32 I used too.

 

I think it is OK, becasue I never saw any information of Kaspershy conficting with Linux

 

Mcafee? After what happened a couple of weeks back?

I personally use ESET Internet Security on 3 PC's, and it has been working great on all 3!

 

I have never used an anti-virus software.. EVER.. I've never had any issues either, but you obviously have to watch where you download from.. I've switched to the mac platform, and I still don't use an anti-virus.. all it does it take up your memory.. especially Norton =O..

 

My computer was attacked by some unknown virus even I use Kaspersky, so I think you are right. The anti-virus software maybe useless when we encounter real strong virus. It is better to leave it go.

 

For me Kaspersky is best for pc/internet security

 

Smart Security and Nod32 from ESET has been working flawlessly since I begun concerning about being protected. No problems so far with minimum load on the computer and easy to use interface. Advanced options and settings is available for users but I have never been in a situation where I needed to change the default settings. Pretty cool Uh

I have tried almost all of the above security programs (just for sport) and one of the really good ones according to others crashed my computer several times without being able to logg windows. So the situation for many I believe is a trial and error test before finding a solution that works.
