Hi - I'm not sure if this is the correct forum to post this but figured if it wasn't I'd find out - and if it is I apologise in advance.

Royal-Search.com virus detected in Google Analytics of website

How do I get rid of this?

It appears under the "acquisitions" (ie, "leads" / "referral" pages).

When I google "royal-search" I get a whole bunch of results about it but I'm not sure if these are designed to further infiltrate it into my computer or website (or wherever it hangs out) or not ... 

in other words I don't trust any of these ...

So.  In plain English please (cos I'm not a tech, I'm a marketer) what do I need to do?
