Advice Request F-secure bank protection issue with AdGuard DNS

[Zartarra]

Hello

Is anyone using F-secure Safe in combination with AdGuard desktop version? I have a strange issue. When the bank protections kicks in, it blocks adguardsvc connections to 127.0.0.1. After that I cannot load a bank site. The issue seems to get triggered when using the DNS Protection in AdGuard. If I disable the DNS protection and make use of the ISP DNS or a custom DNS like NextDNS in a web browser, the banking protection starts and there is no issue with the bank sites. I never had this issue with the combo so it seems to be something recently.

During an active banking mode, all other Internet connections are temporarily disabled. F-Secure secures a device quickly and automatically, but a user has a full control of everything. Banking protection from F-Secure prevents connections, so no malicious software can reach a hacker’s server.

This is what avlab.pl said about F-Secure's banking protection. So that could be the reason.

Did you try to create an "Allow" exception rule in F-Secure Bank Protection for 127.0.0.1?

If that does not work, then you should submit a bug report. They will have to whitelist the adguardsvc process.

Just be aware that if you make the allow exception and it works, should there ever be a banking trojan or other malware that captures credentials on your system, and one of its processes sends packets to 127.0.0.1, then it will bypass F-Secure banking protection.

sidenote anomaly?? I had been seeing small FS banking popup at top of browser when I'd buy something or go to bank site, but lately I noticed the opposite, ie, I'm not seeing that banking popup but I have not changed any FS SAFE settings. Just me?? Did I break something again??
