Someone's tried to get money from my account.

Hi... I went to the Barclays cash machine in Gandía and tried to withdraw 150 euros. The machine spat my card out and told me to consult my bank. When I got home, I tried to log on to my online banking and that wouldn't allow me access either. After a long conversation with Barclays, they've informed me that someone has tried to debit £823 from my account. I only use the card to get cash out, and never to make purchases or pay for meals, diesel, etc. The lady reckoned they got my details from the internet, but the only sites I've used recently are Miss Groovy and Easyjet. Could it be because I've logged onto my Barclays account using Internet Explorer?

I have a seperate Barclays Spanish account, Net. The English account is nothing to do with the Spanish one.
