There is _no_ link -- of course, especially without hyperref ...
(with Evince ...)

... but I see the link with `smb://Test' on the


version of your posting -- so TeXShop or that Apple library
pretends to be smart by offering a link for everything that 
looks like link code. In that case you could ignore the 
"problem", just don't click at the "link", other PDF viewers 
are not that "smart."

However, you write that even `\\Test' appears to be a link. 
It is not a link in your posting in its above form.

Perhaps this occurs with \verb because this way your "smart" 
viewer recognizes a "code font" ... and perhaps a pair of 
backslashes is interpreted as belonging to Windows, and `smb:' 
is the "default protocol," as otherwise `http:' is.
Do you get an smb link from \texttt{\string\\boguslink}} too?
