AV Question

What other AV's run in the memory like ESET?

 

All of them.

 

do you mean load the whole of the signatures in memory?

 

No not all. One that doesn't is Avast afaik. Their RAM usage should be higher if they did.

 

Hard to say exactly, but Ikarus does last I heard, and Emsisoft AM according to Fabian W.

But I do think there are more, but far from all AVs unfortunately.

Though you can exclude the AV's wich are heavily cloud based like Qihoo, Baidu, Panda Cloud, WSA, BD Free, Immunet...that don't have a lot of local stuff to load into the RAM.

But I am sure others can provide info on more vendors, hopefully

 

Thank you,

You understand what I'm saying. I just know of ESET that does this.

I'm pretty sure Kaspersky does.

 

Someone mentioned that Kaspersky used around 250 MB on their system, so if that usage is consistent as in it always uses around the same amount, then yes we can probably include Kaspersky in this group too. But I don't know if that is the case for sure though.

 

You're welcome, maybe we should have a list of AV's that's designed like this, so users that like or are looking for AV's that's designed this way can just check the vendors on the list and test one or some of them out. So users looking for them can skip those that doesn't.

 

It's pretty easy to determine it actually. If at least one of the services shows high RAM usage (like >100MB) in the long run then the AV loads the signatures in the memory. If it only shows a few MB (less than 20MB, commonly less than 10MB), then the AV fools hides the reality from us.

 

When I've used Kaspersky I've seen it at around 130 mb.

 

Some AVs can use 300+ MB one second and then drop to 20MB, these AVs does not have its modules and sigs loaded in the RAM all the time, wich is what we are talking about. And the benefit of having a list with AVs that does this, is that you don't need to install the AV/s to find this out.

 

Which can break the rule.

 

You strongly misunderstand how computers works. Try running anything in a computer with no ram. Have fun.

 

Maybe they have optimized some things engine and/or database etc.. and made it smaller wich in return could lower the RAM usage even if everything still is loaded into the RAM (if they still do, or ever did), but then again I have no clue in this case about Kaspersky.

 

Or you misunderstood the question, or not.

 

Sorry, What rule exactly?

 

Aw c'mon SweX, as a massive poster you shouldv'e known about the no A vs B rule for AVs. That list could have a potential to touch that area.

 

I fail to see that actually, as we don't compare the actual protection between them, and don't talk about wich one that have the best this or that. It's more like an category, like you would make a list of only Cloud Based AV's, Only Free AVs etc etc (not comparing only informing) then one should be able to do the same about the category "everything loaded into the RAM" or whatever, I figure.

But then again I am not requesting a list like that, it is only a suggestion. But with a list like that the OP(and everyone that are wondering) could have found their answer very easy.

 

Well, if it only lists AVs that load signatures in RAM and nothing else, then I agree with you.

 

Swex, I understand the question. AV's or any program in the windows environment, linux or osx requires memory use. If he is asking what other AV's run in memory like ESET the answer would be all of them, as they all run in memory, as does ESET. Its clearly critical to them working just as any other software in a computer environment requires memory, so do AV's.

 

Mhm.... This is NOT about whether certain AVs use the RAM, or does not use the RAM. All AV's do, I/we know that.

 

SweX is on to something though. ESET runs crazy light on my machine (I have plenty of RAM) and I think it has to do with loading more than the other AV's into RAM. Webroot loads nothing into RAM and yet my browsers are slow to close. Maybe it has to do with CPU usage being used vs RAM usage? The AV can have 300 mb of RAM if that's what it takes to get rid of the 'lag'.

 

ESET is the only product I know of, but that does not mean it is the only one. Most probably don't though. This is what happens when everyone complains that they "think" a product is heavy because it uses RAM. The vendors page it all out to hide RAM usage.
