It's security settings in your browser combined with Google and other site indexing services. Auslot was incorrectly blacklisted and hence the warnings.
I never had any for our site on all the multiple devices I checked. It might have had to do with certain links to thier server as we allow them. And when you do, those stay in our database. So any redirect link will cause that warning.
In any case, you should clear out your browser history/cookies. You should do this anyway, so it might be a good time.
You should be fine. Our site is fine.
