Actually, there is one word that stands out in your post that is very important — "our" — and that is important because of the question that arises about you having some sort of internal net where different folks are using computers on that internal net.
Point is that the more people you have using a bunch of computers the easier it is to have somebody make a mistake and accidentally invite some bad bug into your internal net and that means you might want a higher grade of protection.
So I think for anyone to give you a good answer the information about your use of "our" could be useful, BUT I wouldn't be so quick to post information out here in public because that is also a flaw in the area of maintaining security.
But I can sometimes get seriously paranoid about security, and there might be some who will state that I am being too paranoid about the idea you should PM a tech person you think you can trust here on this site, or another site, and do your discussion in that environment where only you and that tech person you have decided to trust can figure things out.
By the way, the — "And stuff like that." — would also have a security professional asking what stuff?
But I am again going to state that with security all sorts of little details posted in public can be a problem if a really skillful bad person is paying attention to what you post. There might be a good professional here in this CompHop Community that wouldn't mind helping you through a private means here or elsewhere.
Not me, by the way. I am not reliable. I am a cancer patient and my medical situation can get very iffy and I might disappear from the Net for days on end because something in the chemotherapy went haywire.
