Remote — unfriendly (7)
I believe the answer is:
distant
This clue is a double definition.
'remote' is the first definition.
(I know that remote can be written as distant)
'unfriendly' is the second definition.
(thesaurus)
(Other definitions for distant that I've seen before include "Far away" , "Unfriendly; far off" , "Remote in time or place" , "Far from - reserved" , "Absent - coming from a far-away place" .)
