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

'it may be a problem for server to secure' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'victory in court umpire's rearranged' is the wordplay.
'victory' becomes 'v'.
'in' means one lot of letters goes inside another.
'rearranged' indicates anagramming the letters.
'court'+'umpires'='courtumpires'
'courtumpires' is an anagram of 'computerirus'.
'v' put inside 'computerirus' is 'COMPUTER VIRUS'.
