tell me why :antivirus size some big some small

tell me if anybody know
why norton , mcfee are so big in size and r not the best.
whereas nod32,avg are small but favourites of everyone.
is there anything to do with the size of the antivirus.
nav 2005 around 100mb.
nav 2006 300 mb.
nod32 11.7 mb.
avg 26.4 mb.

there is a saying in Hindi:

which is bigger, a brain or a buffalo (Akal badi ya bhaiyns)

absolutely agree with u , it doesnt mean that norton and mc afee r better just bcos their installation package size is bigger, just try all the software , and use the one which is best

hey man :
i just wana to know why they have a big installation file ,
they r big companies dont they know that the task can be
done with a small installation.
or do they have some
different technnique of searching viruses.
got my point what i mean .

Hey .. the bigger they are .. the worser they are ..

... NOD32 rulez ...

the bigger AV are generally more resource hungry.

i think ...file size depends upon wat language has been used to code that program like if we code a program using assembly lang. it creates much large program when same task done by machine language

Larger the installation, more the stuff it bundles. Norton comes with many extra tools/softwares (most of which are useless for power user). While on the other hand, Symantec Corp. client, made by same company, is just 20MB or so, and is counted as one of the best AV.

i don't agree to it

norton am not using, am using panda, but still norton is one of my favorites, and you say norton is not good, i suggest you to go to pack.google.com and install norton 2005, you get free lisence for 6 months, use it, and then say it's good or not, and also you need some extra ram, as it uses 100 mb of ram for it's active scanner. the bigger the anti-virus the more strong is the virus data base, and the more ram it uses to run means more active the shield is, though you don't require all that for the home pc, but for a surver you need to think on these topics before taking any antivirus,

hey dude the norton 2006 is of 100MB.

have you seen the interface of AVG? Obviously, that cuts down on the size..

Absolutely good reason Using Windows native interface not only provide a good merger feeling with windows it also keeps app size light.

This is news to me..........
I know of big companies that use Software like Symantec Anti-Virus both at the Server as well as the client Level.....

Dude.... Big AV doesn't mean Strong Virus Database... Better get ur Facts right before commenting on the comments of others....

People here are not Chu***yas as u percieve them to be. This place is a wealth of knowledge..
N BTW, when Norton is ur favorite, Y do u use Panda????

R

try avast 4.7 home edition its free, it has nice database & low on size....
quickly detects attacking ip's & blocks it automatically displaying msgs...

many gr8 features, graphical scanning, better than avg, norton, mcafee....
do telll me after downloading it.....its a blast indeed...i gonna buy avast professional edition

It all depends on the method of active protection used. Some try to scan everything at one go and kill MBs of ram. Some spare the MBs at the cost of safety.
the best mean mix i have found so far has to be avast.

Hi guys, my favourite is THE KASPERSKY. excellent protection, low on resource, take only around 50mb installation space. Scan-time is a little long, but ok for safety purpose.

most remarkable is available update (online) even every minute.

I never used NOD23. can any user of it give a little more detail?

Well its not NOD23 but NOD32..Check its review here.
Its not resource hungry like norton and doesnt give problems to the user and and its very userfriendly

I was very impressed with AVG when I used it for its low profile (norton keeps butting in everywhere)....What's more, it finds viruses better.....But I found Avast slowed my Comp? Was there something wring in what I did, or was it avast's problem (i dont think so, seeing as u pl have praised it so much)

My comp is pretty old....128MB ram 1.6 Ghz, P4

Though the best prevention for viruses is simple common sense... If you see a music video on a p2p network of 40 KB it's almost definitelyt a virus. And don't d/l stuff from shady looking sites. And always scan things you d/l (which is where a low-resource av comes in handy)

i had gotta a virus on my pc which norton could only detect but could not delete.. ultimately i had to restore my c drive.. after dat i ran a scan with norton... it didnt find anything...i uninstalled norton and installed NOD32 V2 ...it found three infections....NOW DECIDE FOR YOURSELF.. I HAVE BECOME AN nod32 fan....i trust this software.

yepee i too have become a nod32 fan , its an absolutely great and fast antivirus.

Kaspersky is still better (11 MB) and detects all intrusions but even NOD is good

I think everybody is just telling u the size of other AV....
Well Why some AVs are big and some small
Lets take the the example of Norton, they are not only the virus scanners but give u some other utilities to maintain ur computer.

they r big companies dont they know that the task can be
done with a small installation.

They do know that task can be completed with very small installation but they if they dont give some other sevices how they will run. Thats the market strategy that we(Companies) are giving this and they are not....
And these companies are providing these utilities for users benefit.
Due to these installations become very large.

I am too not in favour of such heavy installations. I use Avast4.7

Size of an antivirus application depends on the underlying engine, & the code, along with all the features

Norton compared to Kaspersky or NOD32 is big, but u guys are also forgetting that norton Antivirus 2006 has far many more features compared to the other Antivirus, such as worm blocking, network protection etc

some of these features are also in the other AVs, one thing that I would say indeed, that sticking to Windows Native UI & interface helps in reducing the overall size

the code of norton antivirus is age old, which is the biggest reason for it to be a bloat, now with Vista changing it's networking stack, I hope, Norton gets a whole re-write of it's code, with optimization in mind

I use NAV 2005, got 1 GB RAM, & it just sits inside the system, I don't care how much RAM it eats, I disable it when not online anyway, to free up CPU cycles for other things

some have it big...some have it small...doeznt matter !
what matters is how good a job it (the anti-virus) does ! ;-)

maybe becos ppl think, the bigger the better. not many ppl wud pay 2000 rs for a 5 mb software, if they get a 50 mb software for the same price. they will go for the 50 mb software, even if its crap. this may not be wat all think but there surely wud be some ppl who think this way.
