how do i hide virtual machine in finder?

hello... this is probably a really simple question, but the virtual machine (win xp sp3) has appeared in my mac finder window - see attached, the machine named MacBookPro-001B63...

How do I hide or remove that machine, which only appeared today?

Thanks!

 

If you restart Mac OS and machine is still there, it is either another PC, or VM, in house,in neighborhood

 

Thanks John. It's certainly still there after a restart. It's also appeared on my computer at work :-/. When I switch off "Back to my Mac" it disappears, as does my Mac machine ; they both reappear when I turn it back on again.

Are there any other reasons why it might have appeared just after I fiddled with some settings? Any way to hide it or get rid of it?

 

un-fiddle those settings?

 

thanks - i did. actually, all i ended up not fiddling at all, because everything was changed back to how it was.
