Avast Antivirus Engine Server memory leak?
« on: February 24, 2024, 02:08:08 PM »
 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  :(

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

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.
Thank you and good day!
