I believe the answer is:

bugs

(Other definitions for bugs that I've seen before include "Creepy-crawlies in computers" , "Insects or faults in a system or machine" , "Insects or defects in computer programs" , "Errors in computer programs" , "Small crawling creatures or disease-germs" .)

I've seen this clue in The Times.
