Chrome webpage slow to respond with Avast
« on: February 24, 2021, 12:25:40 PM »
Hi,

Since the december update, chrome is really slow on my pc. It seems to freeze up to 10 seconds a lot of time when a page is loading.
I tested it with avast uninstalled and the issue disappear.
I'm on Windows 8.1.

Is it something you can do to fix it ? Maybe it affects only Windows 8.1 as I don't see thread on the forum about that.

Thanks

1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe
2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions..!!)
3. Reinstall Avast with the downloaded installer from point 1.
4. Reboot.

Same problem.
I took the online installer to reinstall it. The link you gave is blocked by chrome.

I finally found an other thread about this problem : https://forum.avast.com/index.php?topic=246736.0

I don't seem to be the only one.

Well this definitely won't help much, but still, maybe your computer is just crappy and it can't handle the protection on, plus chrome is heavy on system resources and maybe, just maybe it maxes out your CPU.

It only happens with avast. I don't think a laptop with an Intel i5 is crappy. The cpu usage when it happens is below 40%.

Hi,

I uploaded the files in the ftp server with my email address for the filename.
I put the password "virus" likes this page says : https://support.avast.com/en-ww/article/160


There is inside the zip file :

chrome-log_23294 (with avast enabled).json
chrome-log_31130 (with avast disabled).json
Console Output.txt

When avast is enabled it shows something like that in the cmd window : USB: usb_device_handle_win.cc:1049 Failed to read descriptor from node connection

This message does not appear when all avast agents are disabled

Thanks

Hi DJ_Rem,

thank you for your cooperation. I see freeze in chrome net log,  and I try to figure out, what it caused. But I need logs from chrome and Avast together, when problem occurs.

1) Enable Debug logging in Avast: Menu -> Settings -> General (on left)-> Troubleshooting -> check Enable debug logging (on bottom)
2) Restart Avast: Right click on Avast icon in tray - next to clock in bottom right corner -> Avast shields control -> click disable for 10 min, confirm ok, and then enable all shields back.
2) Close all chrome windows
3) Open command line: press Windows+r, type cmd and press enter
4) Copy this command to command line and press enter. (just load page with freeze; don't play video, because debug logs can be large and rolled out)
Quote
"c:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --incognito --enable-logging --v=1 --log-net-log=%LOCALAPPDATA%"\Google\Chrome\User Data\chrome_netlog.json" https://www.youtube.com
5) open folder with saved chrome logs: copy this command to command line and press enter
Quote
explorer  %LOCALAPPDATA%"\Google\Chrome\User Data\"
6) Upload files chrome_netlog.json and chrome_debug.log to ftp using https://support.avast.com/en-ww/article/160
7) Send us Avast diagnostic package using https://support.avast.com/en-ww/article/Submit-support-file in Avast: menu  -> settings -> troubleshooting -> send logs -> click Next -> fill your email and click generate (it takes a moment) -> copy File ID and post it here, or send it to me via forum message (I need to identify generated package). You can also upload package yourself to ftp with chrome logs.
8 ) disable Avast debug logging and restart Avast.

I see, there is long list, but I try to explain every step and it could help us to solve this problem. Could you help us one more time?

Hi,

Zip file uploaded to the ftp server. Filename = my email address with "-2" at the end.

Avast debug files are inside also. I think the tool also uploaded it to your server. File ID : J0L9K

Thanks
