This is an extremely strange question, I know! Just about 15 minutes ago, my macbook has decided to change the word 'what' to "supmyninja" whenever and wherever I type it... Why on earth is it doing this?! Any ideas? The only different thing I've done on my laptop this morning is that I used a proxy site to access the US Abercrombie and Fitch website (as it automatically redirects to the UK site). That wouldn't have caused this would it? It looks instinctively like some sort of virus, but I'm hoping it's not! Many thanks.
