I had exactly the same type of call yesterday, here in the UK, but the caller ID was simply "International". He gave an English name - Martin - but he was clearly from somewhere rather warmer and his accent was almost impenetrable. His pitch seemed to be that my computer was sending messages without my knowledge and he needed me to log on so he could take me through the necessary steps to cure it. I managed to avoid this temptation, but the man was persistent and kept ringing back when I said I wasn't interested and put the phone down - probably four times.
