I will assume this 'software' is something like 'Avast' so basically it is an optional language add-on. I think it was made for 'Pirates day' for people to actually enjoy it, it's kinda cool. So basically "English Pirate" is english but in a pirate way. For example: "Ahoy" in english pirate means "Hello" and "Aye" or "Arrr" means 'Yes/ I agree/hmm' and "Ye" is 'you' 'Ahoy Matey!' (means Hello mate!) and 'my' (means me) One of my favorites is "Ahoy, me Hearties!" which means "Hello my friends!" lol it's really fun! I hope I didn't go too much out of topic answering your question lol =D

The only pirate i know of when it comes to computer stuff is a person who steals music, movies, etc. by downloading them off the internet.

a pirate that speaks english? lol :P

Was this software purchased??
