In the past, I've reported two websites that had an F-Secure "unknown" rating in a Google search. It took them about 4-5 days to reply with a secure site affirmation. So I'm thinking this could be the case here as well, unless they speed these type of FP's along quicker :)

Maybe reporting FPs (signature and cloud detections) to Avira would result in a quicker response? F-Secure uses Avira signatures and cloud.

But how much of it due to Avira, and how much is it due to the other scanning engines F-Secure uses, including their propitiatory engines and AmazonAWS? Or, is the Browser protection totally a Avira scanning engine?

I was talking about that particular FP. I am well-aware that F-Secure uses it own BB (Deep Guard) and other engines, but what detected Zen Browser installer was Avira's engine. Regarding F-Secure web protection, I am not sure what F-Secure uses for that. But I believe the heavy lifting when it comes to signature-based detection is coming from Avira engine.

Apologies for my misunderstanding, and throwing the whole kitchen sink at you :)

No no it is great to know that F-Secure uses all that stuff. What I hate about FPs is the fact if you are not an experienced user you do not want to take the risk and add the FP to exclusions, so you report it and wait for the result. Unfortunately, waiting is not always ideal especially when you need to use what was falsely detected.

Reagrding Emsisoft support, maybe it is not always fast, but because I am using their Buisness product, so I am entitled for premium support? I am not really sure about that.

I just tested this browser. It seems fast, but Edge is already fast, feature-rich, and customizable. There is no reason to use this; it is not as secure as Edge or Chrome. Why would someone use it? There is also Edge for Enterprise, which is free and has a feature called Workspace that I didn’t see in other browsers. As a guy who always looks for browsers, I find Edge is the only one that satisfies my needs. Additionally, Eric Lawrence, who has a strong background in web security and development, is working on Edge, which shows they are doing a good job.

So it seems the absence of digital signature is causing many solutions to detect the installer. Was the detection during the download or after it finished?

When Harmony analyzes it before Brave starts downloading (Harmony also downloads it, but inspects it at the same time)

I'm going to test the portable version.

I wanted to try it because it is Firefox-based. Most browsers nowadays are Chromium-based. I have reinstalled Waterfox which is digitally signed and comes with Mozilla telemetry disabled out of the box.

I also tried it recently. Not detect by Microsoft and F Secure. Super cool browser, still some issues but it is in alpha. It can definitely become more mainstream if people contribute to the code.

If any accuracy to these statements, that’s really good:
“No formal benchmark, but starting with a fully charged M1 Max MacBook Pro 16, Arc would use about 40% of the battery for my daily morning routine (loading 120 tabs and reading most of them, doing 25 puzzles, etc. etc.). Zen uses about 10%. YMMV, but that's what I'm seeing. Only Edge is close to Zen in terms of battery usage, using about 15%. And yes, the speed and fluidity of Zen are amazing.”
