18-10-2006, 12:41 PM

Hi friends

Is ther any anti vrus which is good and does not slow the CPU processing

deepak.krishnan · 18-10-2006, 01:01 PM

Try out AVAST Home edition.

Now this is about the 5th time or so I have seen almost similar questions.

samrulez · 18-10-2006, 01:39 PM

avast! really lite!...eats 4MB memory

But better is NOD32 it provides gr8 security in proportion to the resources it uses...

mikeon · 18-10-2006, 01:59 PM

Same here Avast is great

paul_007 · 18-10-2006, 03:02 PM

NOD32 .....though it eats memory but performs very well

shaunak · 18-10-2006, 04:08 PM

Probably the lighest scaner: avast!

anandk · 18-10-2006, 06:42 PM

freeware : avast
paid : kav

try out NAV 2007 if possible, it's not using much RAM here, 8 MB total

i m just waiting for KAV 6 final to relese, i have tried their beta antivirus, it's good still not what i was expecting, like i went to system32 folder & it started scanning everything in that folder in real time & system started crawling for 2 mins.

Also , with a previous beta, when i was downloading itunes for working on an ipod, KAV was scanning that file being downloaded, so CPU usage went to 100%

thats why just waiting for the final version

Absoutely AVAST there is no other antivirus, that I know of, which is free & very lite on sys resources.

Avast is light on RAM but it dosen't have a good detection rate. Try BitDefender. It's far lighter than Norton and has one of the best detection rates in the business.

Vishal Gupta · 18-10-2006, 08:33 PM

One more vote for avast!

Stick · 18-10-2006, 09:14 PM

Another Vote for AVAST, if you want system run without any problem,

I already used ZA (some problem with PC shut down for Win98)
KAV (some futures can not get enabled with Win98)

drvarunmehta · 18-10-2006, 09:34 PM

Look at this thread. Avast is way down the list. What use having an Antivirus just because it's light when it dosen't have a good detection rate?

Zeeshan Quireshi · 19-10-2006, 12:43 PM

mediator · 19-10-2006, 01:51 PM

AVAST and KAspersky

Cool G5 · 19-10-2006, 02:02 PM

Avast Home.

sysfilez · 19-10-2006, 02:39 PM

quick heal is best antivirus in terms of low cpu processing, next in line is kaspersky. i personally use kaspersky.

Kiran.dks · 19-10-2006, 04:35 PM

avast! is the one for you. It has got awesome On-access scanner and web shields.

nix · 19-10-2006, 06:34 PM

just got rid of NAV yesterday and have been running nod32 since yesterday...its low on memory and so far has been doing good job of reporting and deleting viruses...

manas · 19-10-2006, 07:42 PM

NOD32 is light on system resources and has a very good detection rate as well.

Kiran.dks · 20-10-2006, 09:24 AM

@drvarunmehata: I don't believe in reviews made by websites becoz of much variations in reports of different websites. It is left to individuals to decide their best. This is the place to discuss and decide.
Moreover..the report you have posted doesnot consider the amount of system resources consumed in contrast this thread is highlighting in terms of min resources consumed.

drvarunmehta · 20-10-2006, 10:51 AM

The source for the rankings is a very reliable one. It isn't a random website doing reviews.

Anyways the point i'm trying to make is that what use is an AV software (no matter how light on the system) if it dosen't have a good detection rate?
Better to choose a software that actually has a good detection rate.

BitDefender has a very high rating and dosen't use up much more RAM than Avast either. I have used Avast for over a year and found it to be quite good, but only when I started using BitDefender did I realise that Avast dosen't catch all viruses.

Kiran.dks · 21-10-2006, 07:44 AM

@drvarunmehta: Most of them wont go for a resource hug antivirus software. Light on system and also good in detection rates is the people's choice.
Who would install a big resource hug in their Home PC's which consume resources and turn a great configuration PC into a 19th century PC?? Then what is the use of all the money you are putting for that extra CPU speed and extra RAM?Just allow your antivirus software to eat it generously? That is what is happening to Norton. There is no doubt about its detection rates, but still most don't prefer it -just becoz it consumes a hell lot of system resouces. Infact first thing I have done after purchase of my lappie is uninstall it!
Most of us have dont have super computers so as to allow antivirus software to generously to eat a part of system resources and still keep running system fast. It may be good enough for corporate PC's but definetly no for home purpose.
avast! is becoming people's choice. Beautiful interface, light on system and good in detection rates.
