Is my plug-ins "generator hostname:" hacked or can I change it?

I have recently upgraded machines at my work. Our company has also recently had some sort of hack. Literally on my older machine I saw the name change on one of my camera sd cards and partition. It is a mac. Ok, now on to the question...  look at the preferences for plug-ins on the screen shot below...

the hostname address is not my computer, it is a different machine, someone else's pc. It was affected by malware/trojan where their passwords were compromised.

I am looking to see how I can change this and correct it. I am also trying to understand how this could even be set up like it is without manually doing it.

So question 1: Can I fix the address without going through a reloading process?

Question 2: Is this a gateway that could affect my machine or network at my company?

Thanks.
