I have both https://www.twitch.tv/* and  https://www.youtube.com/* in the exclusion list for urls yet avast keeps scanning them.( I did restart shields but it doesn't work)Is this normal behaviour?I recently upgraded to w10 from w7 and I don't remember constant scanning going around.

Update:I can stop the scanning temporarily if I disable and re-enable the shields while watching multiple streams  but as soon as I open a new twitch tab/stream avast goes back to scanning as usual again.

Is this a bug?It's like it can only stop scanning from instances of streams/videos from in-between the disable/enable of the shields but as soon as something new pops up it goes back to scanning(like opening a new tab of twitch or youtube)

Avast Programm version:18.8.2356 (build 18.8.4084.0)

Virus definition 181206-4

I only have the 4 shields installed since the OS  was freshly installed like a couple of hours ago.

Thankfully it doesn't scan While I'm only gaming but I usually have twitch or youtube in the background because I like to listen to podcasts which make scan start scanning again.(which might or might not impact performance.I don't really know tbh it usually only takes 1% every time it scans)

My other option if this is indeed a bug is to disable shields while playing games and listening to streams at the same.Hopefully it shouldn't be a problem since both sites (twitch/youtube) and black desert have legit companies behind them and shouldn't endanger my PC.

Hit uninstall>repaired>rebooted and the problem still persists.Like I said.If I disable shields and re-enable them while watching a stream/s it stops scanning.But as soon as I open a new tab either youtube/twitch it starts scanning again.

- OS..? (32/64 Bit..? - which SP/Build..?)
- Other security related software installed..?
- Which AV(s) did you use before Avast..?

-OS windows 10 home version 1803 (OSbuild 17134.441)
-I have windows defender turned off trough registry (since I use avast)
-None

Some other things I'd like to point out.

-The constant scanning stops when I'm playing games or simply browsing. (but will show come up again if I use twitch/youtube at the same time to listen too in the background but stops as soon as I close them)It seems videos/stream triggers the scan regardless of exclusion
-Usually scan starts to scan once every time I open a site and go away.(I take it this as normal because it does a 1 tiem scan of the site once it loads)


As you can see in the picture below called proof3.Scan is scanning my twitch stream in the background

And  picture proof5 after I disabled/re-enabled scans shields it stops scanning the current open  twitch tab.(Untill I open another twitch or youtube tab which then results in scan starting to scan again.

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.

I did as Instructed.Downloaded both files.

-Rebooted in safe mode used the cleaner.
-restarted PC
-Downloaded offline setupexe.
-went to option in exclusions to re-list https://www.youtube.com/ and https://www.twitch.tv/ in the global whitelist
-Wierdly enough hitting browse for file paths to re-list blackdesert took ages.Avast was basically stuck in a loading screen (probably loading the files or something.still wierd it took so long 5mins for the first time.I tried to browse and exclude another file and this time was instant.)
-Disabled/enabled shields and reboot PC just incase

-On Reboot I went on twitch aaand....problem still persists even on whitelist.
-I tried disabling/enabling shields and it did stop current scanning on current twitch tabs open but it comes back by simply refreshing the twitch page/youtube

-Again.When I open a new page 1 scan happens (which I assume it's normal since it tries to detect anything harmful in a new opened page) and it either closes down or pokes every once in a while at 0.1 cpu usage.I'm ok with this.
- Constant scanning only happens when watching streams or youtube videos (which I have both in exclusions) but doesn't happen when I watch videos in a streaming site.Maybe it's how youtube and twitch deliver their videos?
-Gaming is not effected and the constant scanning either doesn't pop up when starting a game or it's just there for a second for the initial start of the game (Again I think it's normal behaviour)

I am proper stumped.I guess Il just have shields off when visiting youtube/twitch and play games.

I sent a bug report (because it may simply be a bug) with a link to this page just incase.
