Avast Antivirus Engine Server memory leak?

Hi! I have been observing Avast Antivirus Engine Server(Aswengsrv.exe) process memory usage and it’s way higher than it used to be since mid november 2023;

  • on pc boot it consumes up to 150MB of memory, while in the past it consumed max 75MB

  • it hogs 210MB+ of memory daily while in the past it hogged max 130MB, never went above that mark

I’m assuming that’s not normal behavior, I tried uninstalling/reinstalling and repairing Avast already nothing works sadly.

Avast version: 24.1.6099 - build. 24.1.8821.762

Any help would be greatly appreciated! I never had any issues with Avast before, but this issue started around mid november last year and it keeps getting worse each month.

I went to observe here how much it is consuming, here it is in the 81MB range as the attached image states.
Check which version of Avast you are on.

I’m on the latest Avast version 24.1.6099 - build. 24.1.8821.762

For me Engine Server process memory usage grows above 180MB on daily basis, which I definitely feel is not normal.

I agree with you. it is not normal.
Did you restart your PC and check if it increases?

Yeah it still increases even if I restart pc, worse a lot of time it will hog 140 - 150MB after restart too and grow from there.

Only time it drops to 43 - 75MB is after virus definitions update, but even then it will grow back to 120MB+ within an hour or two.

I’m legit feeling it’s something with Avast itself since I tried everything and nothing resolves this issue.

Friend, do the following to see if it will work.
Uninstall and reinstall avast. and check if it is normal.

I tried this multiple times already, usually after every version/build update, still the same :-\

I tried Avast app repair too, didn’t work either

Shame since I legit never had any problems with Avast :frowning:

I have a question, are you using any protection with Avast?

No I have just Avast Free version, nothing else

If you can, please attach a screenshot of said avast process, so we can see.

Here it was hogging 204MB of memory as you can see from attachment. I really feel this isn’t normal at all since it never hogged this much.

And most of the time it hogs up to 150MB of memory on pc startup/boot, it legit never hogged this much before, at most 75MB.

WOW are you that short of memory 204.4 MB (I think the comma 204,4MB in your image is confusing), and you only have 90% of your memory available.

That said mine is only 86.6, see attached, but look at the real memory usage by your browser (whichever it is), mine, Firefox is using 1,086.7 MB now that’s what I call a lot, but I have 8GB of RAM. Still not much in the greater scheme of things.

43% available memory, AVES is using 63.8 MB memory. 16 GB of RAM installed. Normal usage.

You could try a clean install: https://www.avast.com/uninstall-utility#pc followed by a full off-line install: https://forum.avast.com/index.php?topic=326107.0

Mine is currently at 47.4 MB, but I have seen it range from 30 to 130 MB used.

This is my current RAM usage from Avast.
With Avast I find that the use of PC resources is very low compared to other AVs.

Yours looks uncharacteristically low, I have never seen any of the main processes as low as yours.

Now I can’t understand anything. Some times the consumption seems high, and others seem like the consumption is high, does anyone have any explanation? about this?

For the figures that are being talked about here, 204 MB is crazy. When the total memory in use is for everything in the Task Manager figures is only 10% so there is 90% available for use. Just compare that 204MB against what you browser is using when running.

Memory is there to be used and the sum being discussed is miniscule in the greater scheme of things.

My browser is open basically all of the time and there are multiple tabs pinned and open and it uses the lions share of RAM, am I worried about, no! My browser activity is going to be scanned by Avast and raise its memory usage. RAM is there to be used or things would be much slower.

But what he said is that he’s not using anything. and AVAST is consuming very high.

Even at his reported high 204 MB is miniscule in the greater scheme of things, e.g. total memory. As I said memory is there to be used 204MB out of whatever the total is.

Windows startup is a time when there is a lot of activity going on, so it wouldn’t be unexpected to be more active, but even so 204MB I wouldn’t say is excessive. Programs change, updates, etc. and what the Process does could also have an impact on that figure.
