I'm a little stuck... Click here to teach me more about this clue!

'opposes ormuzd' is the definition.
I can't tell whether this defines the answer.

'virile sort topped with unruly hair' is the wordplay.
'virile sort' becomes 'man' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'topped with' is a charade indicator (letters next to each other).
'unruly' is an anagram indicator.
'hair' is an anagram of 'ahri'.
'man' put after 'ahri' is 'AHRIMAN'.

'who' acts as a link.

Can you help me to learn more?

(Another definition for ahriman that I've seen is " Evil spirit".)

I've seen this clue in The Times.
