I'm just going through my routine check over the forum and noticing a lot of your posts... you seem very eager and confused at the same time. I don't mean to scold you for it, or discourage you from trying out Linux, but there's a lot to learn and you would be saving yourself a lot of this confusion and frustration if you just slow down a bit.
As an example, in a few of these posts you were asked where or how you installed something and you couldn't really tell. On top of that, you always seem to point to different sources even when there's a Software Store available built right into Zorin OS.
Clicking around downloading stuff from who knows where is an excellent way of filling your drive pretty quickly with all sorts of junk. The best advice in terms of security is to avoid doing just that. No matter the operating system you're on.
It's not just malware that you should concern yourself about. If you install something that isn't compatible with your system you may leave your system in a bad state that may require re-install of the OS. It will also make it more difficult for you to track down why something doesn't work as expected, and how to fix it. This of course also applies by extension to anyone trying to help you out with that.
So, please remember that easy, does it. Try to use the Software Store as much as possible and pay attention what you install, and why, from where, etc. This will make your whole experience much easier and more enjoyable.
