Immoral behaviour, very cold stuff (4)

Ross

I believe the answer is:

vice

'immoral behaviour' is the definition.
(I've seen this before)

'very cold stuff' is the wordplay.
'very' becomes 'v' (common abbreviation).
'cold stuff' becomes 'ice' (I've seen this before).
'v'+'ice'='VICE'

(Other definitions for vice that I've seen before include "Gripper - in place of - immorality" , "venality?" , "Immorality; clamping device" , "Gripping tool - bad habit" , "As a substitute for; immoral behaviour" .)

I've seen this clue in The Telegraph.
