what is the lightest antivirus ?

what is the lightest antivirus on system on the market .. i really have no experince i used to have macafee which was too heavy on the system and now with the new laptop i want something light and i dont know what is the best around

 

Although it seems many people are starting to talk negatively about Kaspersky, I find it very light on resources. I've been using it forever now, and I never even know it's there. I suffer no degradation in performance even when it's running a full scan. However, I have heard negative remarks about the 2009 version, but I'm not judging until I actually test it out myself.

Other good names are NOD32 and Antivir (which is free). I've heard that BitDefender, though good at detecting threats, is system-intensive. Take that with a grain of salt, however, as I've never actually used it or seen it in action.

 

I have used both nod and KIS2009
Nod32 V3 seems to have some issues with vista x64 and my system used to freeze for a few minutes randomly when I was testing it. KIS however seems to work fine and I feel no performance issues whatsoever

 

ESET NOD32. Period.

 

I have used all these at one time or another: Norton, AVG, Avast and Avira.

Avast and Avira are both very light on resources compared to the other two.

But IMHO, Avira offers the best detection rate and uses the least resources.

So I am still using Avira and very happy with the product. Plus it's free too.

 

I'd say... f-prot But it's not so effective of course.

 

I find Kaspersky work very well, however, there is one catch to it:

After your initial instal, update it and then run a full system scan (physically premove external HDDs if you know they are virus free)

If you don't do the full system scan Kaspersky does slow down your computer - I suspect because it keeps track of every file, rather than the ones coming/going and being created.

But once you've run Kaspersky it works flawlessly as far a I can tell and is hardly noticeable if at all...

(Kaspersky Internet Security 7 for me)

 

I would choose either nod32 or kaspersky or avira, that's for me
atm, I use nod32 since had some issues with kaspersky and avira

avira - I can't get it update, my internet connection just can't make it, too slow

kaspersky, its just cause computer slowdown, but not much though, its just that, when full scan, I have left it for more than one day, and its still haven;t finish, for 60GB hdd.

well, you wouldn't go wrong with either one of those 3

 

For me Avira..and I'm a Avira noob per se! I don't even notice it doing its work..and luckily for me ~ it's working great!

See, I had Trend Micro...and that made a huge mess out of my system..for the longest time.

(knock on wood)??? Oh Lulz

60GB HDD ad Kaspersky took more of a day...something went wrong there...

I think it took about 16 o 18 hours to scan a 250GB HDD internal, a 500 & 250GB HDD external - even plenty of small files...

Although - I have to admit I had a problem with Kaspersky on the SOny Instal which hasn't reoccued since I used the recovery discs...
(Which is the same intal...)

In the end - Kaspersky works perfectly for me... but everyone to his/her own

 

avast works for me

 

I have used Avast for years until we we were given a free 1 year home subscription to Vipre anti virus and anti spy ware by Sunbelt after we purchased a enterprise edition and it is great. Avast is pretty low on resources but Vipre is noticeably less. Also according to the tests Vipre is better but who knows.

 

The problem with tests is that the company's tests always rate their software amongt the best.

There does not seem to be a normed test for antivirus software.
Basically, if it works for you - stick with it, if you've had a problem, change it (or if its too slow, etcetera)

 

Yep there is no set standard on AV tests.

 

try AVG, I really like it, havent noticed any performance hits

 

Dr Web, Nod32, F-Prot, VBA, Command, KAV, Avira are all well-known lightweight AVs which should all run without any performance hit on your computer.

Add to that list Norton AV 2009 which I am using on my laptop. The first time I have used Norton since 2001.

 

bitdefender total security 2009

 

Just upgraded to KIS 2009 from 7 - it seems to run faster...
