Ethical malware's caught out with reverse engineering (8)
I believe the answer is:
virtuous
'ethical' is the definition.
(thesaurus)
'malware's caught out with reverse engineering' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'out' is 'tuo' which is within the answer.
The remaining letters 'virus' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for virtuous that I've seen before include "Upstanding" , "Morally upright" , "Morally good" , "Highly moral" , "Showing high moral standards" .)
