Avast slows down YouTube

[REDACTED]

Hello.

When I want to watch YouTube videos, buffering speed is really slow because of Avast. When I disable it, speed is back to normal. I've tried disabling HTTPS scanning and Intelligent stream scanning but that didn't help. I've tried reinstalling Avast completely using Avast Uninstall Utility and that didn't help either. It's weird because I have Avast installed on other PCs and they don't have this problem.

Does anyone have any ideas what could cause the problem? Thanks.

Which version of Avast?
Any other security software?

I don't have firewall because I'm using Avast Free. I'm sorry, I forgot to mention that.

I use latest version of Avast Free (17.3.2291 build 17.3.3443.0) and GlassWire. Malwarebytes is installed as well but not running in real-time or background.

What happens if you disable GlassWire and watch the videos?

There isn't any issue with the Web Shield relating to streaming.

Disabled Avast and GlassWire in the same time and speed is normal. Enabled GlassWire disabled Avast, slow speed. Enabled Avast, disabled GlassWire, slow speed.

I'm confused. Is there a conflict between those two?

I'm not very familiar with GlassWire and I don't think many members of the community use it either.

PS: Are you sure it's not your internet playing up?

I'm sure that internet is not problem (fiber, 100/100) and on other PCs works fine.

I think I found solution as well. Apparently GlassWire is making problems so I have to uninstall it.

Thanks everyone!
