What triggers 'Connected to safe ethernet' notification?
While enabling computer's (Windows 8.1) network adapter to get ethernet working, which is a common task done hundreds of times on the same machine and the same (cable) internet connection, this time F-Secure SAFE showed a notification above the task bar that said "Connected to safe ethernet" (event is also visible in "Events"-list). There was indeed something unusual going on with the internet connection as Google send an exceptional security alert about suspicious log in as a result of logging in to a google account.
It took quite amount of time to investigate what was going on, but I couldn't determine neither that something suspicious was going on nor that everything was normal. The reason for Google's blocking was likely due to IP-based location being for some reason several hundred kilometers off (according to ISP such inaccuracies are possible). I checked F-Secure logs and the only thing I could found was the following text in DnsCheck.log:
I: DnsCheckHandler::OnDnsCheckFinished: >>> green flyer: Ethernet
So I would like to know what suddenly triggered F-Secure to show the "Connected to safe ethernet" message? The aim is to understand that was there perhaps something malicious going on with the internet connection. If documentation about the event is already available, a link would be appreciated.
