[Exterminator]

I think this question has been beaten to death

Question - Looking for a light security solution for a low end netbook

Best (free) AV for old XP school computers

Free Security Package

Lightest free antivirus with HIPS or Sandbox, except Comodo?

Do you know the resource usage for CIS?

Do you know the resource usage for CIS?

Sorry I do not know that as I don't use it

 

[blueblackwow65]

Qihoo light no problem

 

[Deleted Member 333v73x]

Does ANYONE know the resource usage for Comodo Internet Security?

 

[tonibalas]

Comodo uses about 20 MB with processes, a bit more when updating or scanning.
Since you are an experienced user try to solve the problem of installing CIS
i believe you will enjoy it

Does ANYONE know the resource usage for Comodo Internet Security?

Try it out and you will know
There are a bunch of free AV solutions and you will get a bunch of different answers.
The resource usage is really a moot point in regard to the question at hand as one person will say it affects their system and one will say it is not noticeable."Light" is a vague term and open to interpretation,what is light on my system might be not so light on yours.Unless it is a marked increase in resource usage from one program to another you are probably never going to notice the difference and detection & protection should be the deciding factor.I would rather sacrifice some extra resources than sacrifice on protection.
I used KIS for years and listened to how heavy it was on your system and the how the resource usage was so high.Never once did I have a problem running it on any PC I had it installed on.
Resource usage while important really depends on many factors as to how it is going to run on your computer.You will never really get a true answer to this question in this thread or anywhere else.The only way to know for sure is to try them.
There are the same type of threads already posted in the forums.Personally I would skim through them and pick a couple you might want to try and give them a go.

For a second I thought I had a dejavu. Surely OP can do a search to see the several scattered around threads.

In any case, all are light, depending on your hardware. an example: CIS used around 30MB RAM on one of my systems but on another was over 40.

Plus while I go by the actual definition of light, most are just interested in RAM usage.

Do you know the resource usage for CIS?

Around 5 megabytes.

Panda free antivirus
Qihoo 360
Malwarebytes free

Depending upon your system and requirement, many free antiviruses are out there, but you have to use more than 1 to cover for a paid security solution which provides all-around protection.

I would go with Bitdefender Free. Really Good detection (Bitdefender Free has the same engine of the paid one). Really Good web blocker, phishing detections in the Free version! Active virus control is also really good (heuristics). However, you have no customisation (it's a set and forget product). I also agree with quihoo 360 but I don't like their privacy policy and the web blocker seems to be buggy (it doesn't block the page in time and lets you download the malware le access a phishing page)

 

[Pat MacKnife]

1. Sophos home (also with BB and malicious web blocking)
2. Qihoo 360 TS (webprotection)
3. Panda free (webprotection)
4. Avira free (but avira browser safety does not support on Edge)

Cis is okey, but wouldn't bother with it.
CF with an free antivirus like, qihoo tse or avira, for better signatures.

 

[CMLew]

Tried all of this combo below. All are 100MB or lower.
1) CIS + MBAE
2) Avira + CFW
3) Bitdefender Free + NVT ERP* + WF
4) NVT ERP* + MBAE + ShadeSandbox + WF
5) WD + WF
6) CFW + NVT ERP*

*Lock Down Mode

 

[bunchuu]

if you trust Chinese company: Qihoo TS 360
else
avira is good choice. combine it with MBAE free and ZAM free (as on demand scanner).

 

[XavierGaming]

I've tried Panda Free AV on my laptop and its memory usage was 0.1 MB, cpu usage was 0.

 

[Anupam]

My vote goes to Qihoo 360.
You have low end system? no problem - Use Cloud Only Engines.
You don't want extra cleanup option? no problem - Use TSE.

Don't bother much about Chinese Company. It's a microsoft gold certified partner. Also if you think only Chinese software steals privacy then you are living in your dream.

But again as exterminator already told

I think this question has been beaten to death

 

[Tabeer]

My vote goes to microsoft security essentials
light and easy to use.

 

[jerzy601]

I have used many programs antyvirusowych but for me, the best is Avira Free is so install and forget, this added Zemana Anti-Malware Free Premium and Mbam and is well do not need anything more.
My voice is AviraFree.

WD on w10 is somewhat superior to MSE and as usually downloaded malware samples and guess what WD cleaned w/o any problems while MSE needed a scan to confirm whether its a malware or not.
