spyware

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

'bad apps?' is the definition.
I know nothing about this answer so I can't judge whether this works.

'last ones in company now spreading free' is the wordplay.
'last ones in' indicates one should take the final letters (I've seen 'last one in' mean this).
'spreading' means one lot of letters goes inside another (inserted letters spread others open).
'free' becomes 'spare' (synonyms).
The last letters of 'company now' are 'yw'.
'yw' inserted within 'spare' is 'SPYWARE'.

Can you help me to learn more?

(Another definition for spyware that I've seen is " Application".)

I've seen this clue in The Independent.
