I tried reinstalling steam because of an earlier issue, which lead to a stuff-load more of issues which were only half-way resolved, viruses and such.
Anyways as I tried reinstalling steam, and this keeps coming up.

and as you can see, I have a clear connection to the internet.
I tried logging in through the steam website, and when it requests a code being sent to me e-mail, I can only go through my entrance page of my log-in, and my inbox, but not any other folder to check if it's there. I also haven't received any new e-mails apparently since the first of March, which makes no sense at all.
