My girlfriend had some funny charges appear on her bank statement, one was $100 yesterday and today she had one that was $263. It looked like it was a charge for using google adwords or something involving it, which she has never used. Is this probably a sign that someone has stolen her identity? Or is it a Google issue? Has anyone experienced anything like this?

Its sounds like someone stole her ID. Sge should call her credit card co. ASAP!
