Lightest Antivirus

you may see a small difference but nothing really noticable one thing about 64bit apps is they usually use more memory and disk space than the 32bit version.

 

so, neither of you tried twister antivirus guess not..

 

Well when you stick your neck way out like that...LOL.

 

MSE without a doubt

 

ESET Nod32 hands down.

 

MSE 32-bit on Windows XP Pro SP3, Windows 7 Ultimate 32-bit
MSE 64-bit on Windows 7 Ultimate 64-bit

 

In real life, panda cloud really is the lightest

 

That's probably true. I couldn't believe how fast my laptop worked after running Panda Cloud Free. Unfortunately it was a bit 'false-positive city', so it only lasted a day. Shame though, it was incredibly light.

 

I voted for ESET because it uses only 45 MB RAM and 0.5 GHz of processor speed

Somebody can equal that?

 

Add Disk I/O, and then we're talking.

Where did you get the GHz info from? 0.5 is a lot by the way, unless you mean MHz.

 

Umm, yah! that's what I listed, and it looks like the poll agrees with me for the most part.

 

I'm testing Vipre and Avast on two slow machines of similar specifications and they are certainly lighter and faster than Avira (I have Avira Premium on a fast machine). In terms of memory usage both Vipre and Avast are the same, Vipre seems to be faster than Avast though.

 

Interesting, good to know

 

There are a number of benchmarks here. http://www.raymond.cc/antivirus/

 

But Raymond's tests wasn't made on a "slow snail" machine.

I got a Snail my self, therefore I find it great to know that Both Vipre and Avast runs pretty
smooth on low-end systems as well, just as my all-time fave one of course.

 

As you can see on the Av comparative tests Panda and Avast got very high score though both have many false positive, but thats OK rather than it did not caught everything.

 

Yes but that is very unusual for Avast But not for Panda.

BTW did you post in the right thread?

 

Who in the world rated Avast as the lightest!

Heck, NOD32 and even Eset Smart Security blow it out of the water when it comes to light system usage and performance.

Even Avira AntiVir is lighter on the system than Avast

 

all 3 are very light but, one that I had found to drastically improve of late is MSE.

 

Avast is my favorite AV but I will have to agree with you on this.

On several different systems, I have tired almost all of the popular AV's.

Here is my findings to the lightest AV's:

1. Avira AntiVir
2. Nod32 (latest version) v.2.7 is lighter than Avira AntiVir.
3. Avast
4. Panda Cloud Antivirus
5. Microsoft Security Essentials
6. Norton 2011 (2010 version is lighter, 2009 even lighter than 2010)

Anything after #6 I wouldn't call light.

Thanks.

 

Not so long ago Dr. Web and F-Prot were oft mentioned and praised as being the lightest.
Now I see only one vote for Dr. Web, and zero for F-Prot?
Ah, how the AV market changes...

 

In my opinion,I still think that Avast! is lighter than ESET.

 

i use and own both ess and avast and its pretty close between them but imo avast is for sure lighter overall then ess is. i am talking about the suite though not just the av.

 

Avast.

 

I agree, I do not use it, but I am installing it on all PCs I fix, replacing my old choices like AVG, Avast and Avira and it runs really light, friends are satisfied so far.
