Can abilities with a [Click] cost be used during a run?
No. If an ability has a [Click] as part of its cost, it can only be used as a main action in the controlling player's turn. It cannot be used on the other player's turn or during a run.

From the rules (PDF) page 21, under Paid Abilities (emphasis mine):


  Paid abilities can be triggered at the beginning of each turn, 
  before and after each player action, and at certain points during 
  a run, unless the ability requires a click, in which case it must be 
  triggered as an action.
