Brave vs. F-Secure
Brave: 1.84.135 (Official Build) (64-Bit)
/ Base: Chromium 142.0.7444.135
F-Secure: Version 25.10 (Total)
OS: Win 11Pro 24H2
When I start Brave with device protection enabled, it takes 30 seconds or longer to start up and open the first website. When I disable device protection, the browser starts up in about 1 second and the first page loads immediately. I have now marked brave.exe as excluded in the application and file control. Now everything works. But that can't be right. I had the same problem before with the ZEN browser, but there are no problems with native Firefox or Edge. Oh, and because I've read it here in the forum many times: No, I don't use a VPN.
I would appreciate your help!

Hi @Chrisx3
Yes, I had the same issue with Brave and F-Secure on Windows 11, you are not alone. I'm not sure of adding Brave into exclusions is a good idea, as you're probably diminishing the Scam Protection browsers ability to protect you (Brave is Chromium based, I install the extension from the Chrome store link, so there is protection there in that way as well). A mods or employees reply here would be helpful to confirm what a Google Gemini search using this phrase came up with:
Will adding a browser into an antivirus exceptions jeopardize the browsers ability to protect me while online?
When you add your browser to the antivirus exceptions list (sometimes called a "whitelist" or "exclusion"), you are telling the AV program to stop scanning or monitoring that specific application.
The primary risk is that you disable the AV's ability to scan files and network activity initiated by the browser.
- Unscanned Downloads: The antivirus may no longer scan a file that your browser downloads for malware, allowing a virus to be saved to your hard drive undetected.
- Disabled Behavioral Monitoring: If a malicious script or extension manages to exploit a vulnerability in your browser, the antivirus is less likely to detect the suspicious behavior, as it has been told to trust the browser process completely.
- Bypassed Web Shield: Some AVs have a "Web Shield" component that inspects web traffic before it even gets to the browser. Excluding the browser process can sometimes bypass this critical, real-time inspection of network traffic.
It seemed to be more of an issue on Windows 11, than my Windows 10 PC. So unfortunately, besides using a different browser, I don't have a solution for you but to maybe contact offline support, unless someone else here has an idea for you, us. Scroll down the page for chat or phone support and see what they have to say.
Kind regards.

@Ville Just a bit of a back story. When I was having the Brave slow start up issue (my favorite browser) on this Windows 11 laptop (now is on 25H2), I uninstalled F-Secure and used Avast Free (no Brave issues).
After seeing your post, I uninstalled Avast, used their uninstall tool, then did a manual Folder search and a Registry search for leftovers. Cleaned out the temp and %temp% files and downloaded F-Secure from the portal. There is no longer the Brave issue of long hesitations in opening Brave using the taskbar icon. All of the browsers load "instantaneously", Brave, Chrome and Edge with or without the Firewall sensor being enabled or disabled, including with or without the VPN being enabled :) I did multiple Brave starts and restarts, as well as Windows restarts and shutdowns. It's working great, F-Secure Total v25.10
If the Brave issue should ever happen again, I'll try disabling the Firewall sensor (it's enabled now).
@Chrisx3 if you wanted to try an uninstall and reinstall, that's up to you. But if you do, be sure to backup your Password Vault, unless you have another device with F-Secure to sync to. You can also use the Uninstall tool, but I've found there are always 2 folders leftover that I delete, in hidden files/ProgramData and Users/computer name/App data/Local.

Interesting. I turned off the firewall sensor. It didn't work at first, but after I disabled and then re-enabled device protection (without firewall sensor), Brave suddenly stopped causing problems. So yes, it helped (after a classic “have you tried turning it off and on again?” :)).
To me, this looks like an incompatibility between Brave and this one feature from F-Secure. Some kind of bug? Are the developers reading this and will they maybe add it to their “to-do” list? Brave isn't exactly a total oddity...
Tanks!

I agree, it would be nice to figure out, but in general it may still be a work in progress, especially with Brave, but at least they now have our feedback to go by. From this thread:
