Naughty creature causing failure in electronic devices? (7)

I believe the answer is:

gremlin

(Other definitions for gremlin that I've seen before include "Troublemaker (in the machinery?)" , "Mischievous sprite" , "Trouble-making imp" , "Cause of technical fault" , "Imp causing mechanical problems?" .)

I've seen this clue in The Guardian.
