Title: Hard disk usage 100% when starting the PC
Post by: Nunzio77 on November 13, 2022, 06:06:44 PM
Hello,
I noticed that when I start the PC, for many minutes (about 10/15 minutes) the hard disk usage is high, in total it remains at 100% and the app that uses the hard disk the most is Avast antivirus.

It's normal?

You are not alone seeing that. It has been annoying me for the past few versions of avast free. Clearing all my Browser caches seems to help a little but HDD is still being hammered by Avast for minutes after startup. I don't know what the hell it is doing with the HDD for so long after startup, maybe it is scanning the whole HDD every time. I have just been putting up with it.

If Avast have an explanation, please share it with us frustrated users.

@ Nunzio77

Your image isn't showing Avast as the culprit - just that the Disk column is showing a total of 100%, not what is responsible for that.  If it is Avast you need to scroll down to show where Avast is using this disk activity.

As in my image listed by name for all Avast processes, this image is for explanation only as it isn't directly after startup.

I would also suggest adding your system specs in your forum profile > signature.

The characteristics of my PC and operating system are in my signature.
During normal PC operation, after those indicated minutes of PC startup, Avast's resource situation is similar to yours. I'm talking about the minutes after starting up the PC in which Avast is the process that writes the most to the hard disk as you can see from the image for many minutes. It obviously contributes very actively to the total use of the hard disk. The problem is that it takes many minutes.

Yes, but you don't show it, so there is no real way to identify why.

This however can be difficult right after startup, but try and get to the desktop task manager and try and capture the actual avast task responsible.  If this was when your screenshot was taken you should be able to scroll down (and order by the Name column, grouping all the avast tasks together). 

Whilst your system spec is now old, my old Win XP Pro PC desktop had a Core 2 Duo and 4GB ram (this is almost 5 years ago) and I can't recall such issues.  However Avast has moved forward too.

I would also ask if you have a lot of apps/programs set to run on startup ?
If so try limiting those to see there is one causing avast to scan disk activity.

Here are the print screens.
Auto-running apps are only the essential ones.

I think part of the problem here is the values displayed in that column, as it is showing 4,3 MB/s (MegaBytes per second) in your image, which isn't a value I would associate with Hard Drive activity/usage and how this is converted to arrive at 100% of what.  I'm not even sure this figure is accurate, as 100% of what your disk being full or 100% activity. 

All I can think of is Avasts Service is accessing 4.3Mbs of data per second, but then every value in that column when added up would have represent the physical limit of data accessed per second.  Even in your previous image the Avast Service was only showing 1,6 MB/s and at the same time Disk was showing 100%

@DavidR and all, so this is still a sign that Avast slows down during the first few moments of starting up the PC during its use?
Title: Re: Hard disk usage 100% when starting the PC
Post by: rocksteady on November 18, 2022, 01:03:21 PM
From what I see on Task Manager (Win10 22H2) at startup, Disk runs 100% for ten mins or so. When Task Manager is sorted on Disk load, there are different Avast processes showing top or near top contribututors that burden. I have got used to not trying to doing anything constructive on the PC until the disk thrashing eventually calms down. For me this is not new to recent Avast Free versions but has been a pain for some time.
Title: Re: Hard disk usage 100% when starting the PC
Post by: Rundvleeskroket on November 18, 2022, 01:43:48 PM
Is this on SSD or on a traditional spinning HDD?

Disk thrashing sounds like the OS and/or Avast and/or other applications want to do a lot of small reads and writes. A HDD can't deal with that very well, whereas an SSD handles that much better.

I've had my OS on SSD since 2009 and can't imagine going back. This year even my mass storage went SSD. No more HDD in the PC. Faster, quieter, less moving parts.

There will come a time, and we may already be there, where an SSD is expected. The OS and apps will be written with an SSD in mind. This might be what is going on.

When the resolution?
Title: Re: Hard disk usage 100% when starting the PC
Post by: DavidR on November 19, 2022, 09:07:43 PM
When the resolution?

The problem with making a fix, is they first have to identify the problem.  From what has been covered in this topic doesn't give enough to identify the issue to attempt a fix.

Ordinarily Avast would ask you to Record a performance problem - Avast UI > Settings > General ? Troubleshooting > Record a performance problem - Open Recorder - Start Recording. 

I don't know what happens after this as I have never done this.  I guess having given a brief description (here I would give the URL to this topic as further reference) - Start Recording.  You would have to restart after that to try and replicate the problem and have the monitoring recorded. After this disk usage activity dies down stop the recording.  Presumably this would then need to be submitted to avast for analysis (I don't know how, never having used this function).

Hi,

I expose what I mentioned in the forum in Spanish: Reading the forum in English I notice several issues related to the ram or the slow start of the antivirus interface and that is why my question: Normal behavior of the Antivirus when starting the PC? Is it a change? I noticed about 3 months ago and I thought either it's an error or it's to optimize the start, if so it generates 2 problems: low performance when starting and poor performance during use. Why? Windows is terrible managing the cache and Ram , I suppose that users like me with 8Gb of ram or less will notice it more or slow hard drives. By the way, a few weeks ago I installed a laptop with Windows 10 and Avast had the same behavior.

Greetings and sorry for the English that I use as a translator

For now I switched to another AV Free. For the way I use the PC, I often turn it off and on again, so this was a very annoying thing.
When I see that the problem has been solved maybe I will come back to use Avast Free again.
So for now I'm monitoring this thread and see if the problem will be resolved.
Thank you.

Thank you Nunzio77, I fully understand you pain and I am really sorry for not being able to help you more at the moment. But since this is not happening in our testing environment, we can't really say which component or which part of the product is responsible for the HDD load. The performance recording is the easiest way how to get more information. Thank you.

I gave Avast Free another chance.  :D
I reinstalled the latest version and for the moment this problem seems to be gone.
Now when I start the PC the hard drive percentage stays at 100% for about 3 minutes maximum, which is understandable.
So it is probable that with this new version the previous problem has been solved.
Well, I'm very happy to use Avast Free again.  :) ;)

I hope the use of resources during PC startup will be improved with the next releases. 
Especially for older PCs and with HHD.

Post by: VictorPst on January 26, 2023, 10:36:33 PM
I had the free version for a few months and at first it took 100% of my HDD for about 5 minutes now it takes less than 1 minute and i didn't make any changes to my computer, only upgraded to windows 11 but i don't think that is too relevant.
Title: Re: Hard disk usage 100% when starting the PC
Post by: DavidR on January 26, 2023, 11:35:04 PM
I still can't get my head around the 100% of HDD, to me this can't be capacity but something else (write to or read from).  As it can't possibly completely write to every part of your HDDs storage capacity.

My Primary drive is a 256GB SSD
My secondary drive 1TB (data storage) is HDD and there are occasional spikes lasting seconds yet it really has no impact on my system.

What I don't get is where you are getting that Avast is responsible for this usage as that isn't shown, at boot this activity will generally be the OS opening startup programs, etc. 

I would certainly suggest paring down just what you need to open immediately and the remainder only open when required.  I'm very strict in what I allow to open on boot, otherwise it is only opened when I require it and closed if not going to be used.

I just bought the Avast premium package and i also notice, that my HDD (just a data drive, my system is on a SSD) is running for 2-3 minutes.
I didn't check the system load, its just annoying, since its "loud".
This only happend after activating all the features from premium and doing all the recommended scans and things.

This did never happen with Avast free, but always since premium, so some "service" is doing something at each start, like a scan of the HDD.
I couldn't find anything in the options about a scan at each start of windows though.
Title: Re: Hard disk usage 100% when starting the PC
Post by: DavidR on January 28, 2023, 06:08:51 PM
As I mentioned, Avast being an on-access antivirus scanner, at boot if you regularly have lost of programs run on start up, be brutal.

Quote from: DavidR
I would also ask if you have a lot of apps/programs set to run on startup ?
If so try limiting those to see there is one causing avast to scan disk activity.

For every program starting avast is going to scan the executables and actions of the program.  Try disabling the startup items one at a time and see if one stands out, e.g. reduces this impact.

I have never felt the need for the extras included in the Premium version, so I would look at the additional components.  Try disabling them one at a time and see if one stands out, e.g. reduces this impact.

Post by: Tom158 on January 29, 2023, 02:44:26 PM
I just checked my task manager at start and in my case it is as i suspected. It's the Avast services, that scan or do something at start. Mostly the "premium clean up" not sure, why it would need to scan everything right at the start of windows, rather than at fixed dates (which is disabled), or when i ask the software to do it.
I find things like that rather annoying, so i de-installed the whole "feature".

Right now there is not much "premium" left for me and i have more problems than before to be honest, might actually look into a refund here and go back to basic...

Guys, this problem doesn't happens when PC starts but ...... every time "AvastSvc.exe" is started.

it's incredible .... this issue occurs even when All Shields are disabled ... Very Strange what causes intensive operations on Disk even an SSD is used at 100%.

Topic started since November and ..... no fix until now :(

i created a topic here (before i see this topic) :

hi,

There is big issue with Avast ...... Disk usage is impressive !!!!!

Avast uses 100% of HDD and SSD for a long time everytime Avast Service is launched (it's like if it scans every file in installation folder) and hundreds of files are read !!!

Every time i launch avast ... it reads hundreds of files (files that don't have any link with the functioning of avast).

You can test it easily ... launch "resource monitor" and enjoy the "AvastSVC.exe" activity !!!!

So if you have HDD so you can add 1 or 2 minutes to windows start to be operational.

With HDD Avast Launch takes more time than All Windows Services to Start ... it's amazing :D

This happens Even when all shields are disabled.

Avast was a very light software .... now it is becoming a heavy software like Kaspersky and others :(

If they fix this Avast is really light on resource usage.
Because only when starting Avast is heavy for about 3-4 minutes when starting the PC, after CPU usage, RAM usage and hard disk usage it's all very low.
It is useless to run a deep scan every time a "clean" PC starts up.

Try not to look at this as a whole thing, but take it one step at a time.
1.  Download the file.  Ordinarily it would go to your default download folder.
2.  Google - https://www.minitool.com/news/elevated-command-prompt.html
3.  go to the folder with downloaded file avast-profile.wprp - should be 1. above.
3a. - start recording via command wpr.exe -start avast-profile.wprp (or with newest Avast Antivirus: wpr.exe -start "c:\ProgramData\Avast Software\Avast\profile.wprp") - just copy and past the bold text into the cmd window.  Your folder will be different to mine in the location before the command.
once you have reproduced the problem you can stop it from the cmd prompt in the same way you started
4.  stop recording via command wpr -stop avast-log.etl

- ZIP the log file avast-log.etl and share it via some cloud storage (google-drive, dropbox, one-drive) or avast FTP sever
- provide a link to the zipped log file via avast forum

Post by: DavidR on March 03, 2023, 09:55:50 PM
OK
Looking again at the first line of the information
- download the configuration file from http://public.avast.com/~nix/users/wpr/avast-profile.wprp to some local folder (this step is not necessary on newest installation of Avast Antivirus)

So according the the above you may not need to download it with the latest versions of Avast whatever version that started from.  Not even sure if you would still need to run the cmd

One thing for sure these instructions really need to be reviewed in regard to (this step is not necessary on newest installation of Avast Antivirus)[/i]
What is considered newest installation of Avast and where would this file be located (may not even be needed).

However, I'm wondering if all of this is even required if there is no need to download:
1.  Using the Avast UI > Settings > Troubleshooting > Record a performance problem (enable the Logs - Enable debug logging) now click the Open Recorder (see attached image).
2.  Reproduce the problem so it can be recorded.
3.  Enter the Avast UI > Settings > Troubleshooting > Record a performance problem - uncheck the Enable debug logging.  That should stop these excessive debug logs continuing.
4.  My guess is that these debug logs would be compressed and uploaded to Avast with a unique code that would be also given to you to record in the forums so your log can be found and linked to your topic.

OR

With newest Avast Antivirus whatever this is:
1. Just run the CMD line mentioned before, wpr.exe -start "c:\ProgramData\Avast Software\Avast\profile.wprp"

2.  Does this generate the report, compress and upload it to avast and give you the Unique ID to post in the forums.

One thing for sure this procedure need a lot of clarification and that instruction rewritten.

NOTE: by the end of this pondering, I felt like I had been chasing my tail round a tree and caught up with it.  So I'm going to wait for answers, clarification and a rewrite of the requirements.

I performed two within seconds.
This was the easiest and fastest solution.

Didn't it give you a unique code, so they can link what has been received with you in the forum.
It also seems to be somewhat fast given what you first reported:
Quote from: Nunzio77
Hello,
I noticed that when I start the PC, for many minutes (about 10/15 minutes) the hard disk usage is high, in total it remains at 100% and the app that uses the hard disk the most is Avast antivirus.

So to replicate this I would have thought you would need to initiate the Record a performance problem and restart your system and after the delay (performance hit), then:
Enter the Avast UI > Settings > Troubleshooting > Record a performance problem - uncheck the Enable debug logging, to conclude the recording of the performance problem  ???

Now, if only Avast would update the instruction they give a link to.

@DavidR : i made a 600 MB log file for you (and it is just 1 minute of Record) :p

i use windows 7+ HDD because it's the best platform to reproduce easily the problem (AvastSVC.exe is locked in W10 so i can't do tests without be altered by other processes).

Why in W7 we can kill AvastSVc.exe and not in W10 ? ... you can resolve this soon ?

It isn't for me as such (an Avast User, like you) but for the Avast Team to analyse.

I have tried to contact jan.svoboda to get back to the topic (being a Saturday it might be a couple of days).

No problem, only an Avast user that has been using Avast for over 19 years :)

Its been happening for years so i dont think thats a bug, it's probably an Avast feature. Constantly scanning everything. This is really annoying. Everytime i'm starting my PC 100% HDD usage for a few minutes caused by Avast, everytime i'm starting to download a game from Steam 100% HDD usage for a few minutes caused by Avast, evertime im uninstaling a game from Steam 100% HDD usage for a few minutes caused by Avast. Sometimes it's even happening right after closing the game. It's ridiculous.

On a side note: since yesterday Avast is even blocking me from accessing Steam on my internet browser thanks to its Web/Mail Shield saying that certificate is outdated or something.

Years ???? no man i have avast since 10 years and never have this problem. i think this problem appears in 2022.

it seems you have a specific problem in your pc, our problem only appears when AvastSVC.exe starts (it happens even when all shields are off).

Hello,
thank you very much (Nunzio77 a _Mamide_) for providing performance logs. The issue seems to be connected to the applying the VPS update. Unfortunately we don't see the exact reason, why is this happening in the performance logs due to some in product optimizations. I would like to kindly ask you for providing one more performance log with modified settings of AV application.

Please turn off the Avast Self-Defense in UI settings (troubleshooting section).

The please add DWORD registry value "DisableCPUFeatures" to this registry path "[HKEY_LOCAL_MACHINE\SOFTWARE\Avast Software\Avast\properties\settings\Debug]", and set the value to 00001000 (HEX).
You can also try to import  the attached registry key file, rename the file "disable_opt.txt" to "disable_opt.reg" (change the file extension from TXT to REG) and press enter on a file and allow the importing to windows registry settings.

Now you can re-enable the Avast Self-Defense and then (this is important) please reboot the PC.

After the PC reboot please wait or reproduce the issue and create the new performance recording, either by xperf command or by launching the recording from UI settings (troubleshooting section).

Please let us know after you upload the recording or let us know where you've uploaded the performance log.

We are very sorry for these kind of troubles and thank you very much for helping us to localize this issue. This is very appreciated. Thank you.

Thanks so much for the feedback.  I will be able to do what is requested not before 12/03/23, as I am on vacation and I don't have my PC with me.  As soon as I can do it, I will also communicate it here.

Thank you very much _Mamide_, this is great. We now see the reason, it's connected to internal Avast health check which calculates hashes of all avast files on the disk. I have initiated internal discussion with developers owning this feature and we will start working on some optimization/fix. Once more thank you, we don't need any more uploads of performance logs, this one is perfect.

How can I install the beta? 
Do I need to download the setup file and install it over already installed Avast Free? 
Don't you run the risk of creating problems? 
Or is it better to wait for the final version?

Thanks @jan.svoboda!  :)
When will the final version with this beta fix come out? Hopefully I could wait for the release of the final version with this fix.

I have had the same issue on Win 11 22H2 for 6 months or a little more than that. I just thought it was a 22H2 thing. A bit later I thought it was a defective SSD, so I replaced it and fresh installed Win 11 on the new ssd but the 100% disk usage was still there for 20-30 minutes despite the actual transfer rate in task manager being very small and the PC being locked up/frozen for several minutes at a time. Then i replaced the sata cables but the problem persisted. I eventually uninstalled AVAST and the problem disappeared immediately after reboot. I'll try the beta to see if it helps and report back.

Is it maybe a queue depth issue or something like that or a mismatch between the new security features in Windows and drivers or something like that?

Specs: ASUS PN51-E1, Ryzen 5700U, 32GB RAM, 860 QVO 2tb, 870 EVO 2tb, Windows 11 22H2.

Edit: Nope, it worked for one reboot after Avast was uninstalled but it's back now with no Avast installed, so my problem is most likely unrelated to Avast. Sorry.

Anyone still experiencing this problem?
After the beta and therefore the last release of the official version, has the problem been solved?
At the moment I have uninstalled Avast Free as this problem was very annoying every time I start the PC.

I reinstalled Avast Free and the problem seems to have been solved. 
Hard drive usage is only high for about 1 or 2 minutes after I start my PC, but I guess that's normal since I have an older PC with HDD.

Thanks Avast for fixing the problem. :D
