Yeah, I think this is the reason. Avast uses SSLKEYLOGFILE which seems to cause extra disk writes compared to the other method. Avast can also use the other method; they use it in any other browser outside of Chrome, Edge and Firefox; for example, Brave.
I admired its method for not breaking the original certificate, but looks everything comes at a cost.
I assume McAfee does not perform HTTPS scanning either?
McAfee does not use an MITM proxy to decrypt HTTPS. So, like Microsoft Defender, it will scan your downloads once they're completed.
Thank you for your reply. That makes sense. And I like it, because I don't like it when a third-party AV slows down the browsing process. Kaspersky is my favorite product, but I don't like it for this reason, and I have other reasons too. It integrates too deeply into Windows. And I think the https scanning is noticeable while browsing.
Do you mean ESET is doing HTTPS on YouTube for you? If yes then that's odd as it doesn't do on mine. If it's also not doing it for you then yeah it's intentional from ESET to whitelist YouTube.
I really like the WebAdvisor extension. I usually use it even if I have a different third-party AV installed.
Yeah, I like Kaspersky but I always felt and also proven by fact that on average Kaspersky has the most impact on web browsing speed among Avast, ESET, Bitdefender and Kaspersky. Usually, I disabled Kaspersky's HTTPS scanning when I used it.
Ohhh...sorry, I wrote it down wrong. You're right that when using Eset, there is no HTTPS scanning for YouTube videos. I wrote it down wrong. And I've noticed this many times. This way, videos load faster in full resolution and there are no problems. The same is true for McAfee, because there is no HTTPS scanning there either. I don't know about you, but for me, the most important thing about third-party AV software is that I feel its presence on my computer as little as possible. It should protect me, but have a minimal impact on my computer experience.
ESET uses their internal witelist for HTTPS scanning. You can also disable it if you wish to scan all traffic:
Yeah, lightness is important. McAfee is probably the lightest AV at the moment. It only scans on execution, which also helps with performance.
Yeah, I'm aware of this. I even manually put some sites on the ignore list from the option above your marked one to disable HTTPS on some specific sites. But that option doesn't work as reliably anymore for me.
You can make Avast behave the same way by deselecting other scan options in settings.
The more powerful the behavioral shield, the more OS infiltration, the more remains after uninstall.
The truth is that the situation is more nuanced for me. Let me give you an example: I run Kerish Doctor to clean up the system, and it runs very slowly alongside McAfee and Kaspersky. I guess it's because the two AV engines are monitoring its activity! With ESET, this happens lightning fast. And the cleanup itself is not just a check. So Kerish Doctor runs faster under ESET.
Everything works faster with ESET.
That's what I'm experiencing. I'm not convinced about everything yet, but I can see it in the system.
I see. So you found an area where McAfee is slow for you.
