The Office of Fair Trading is warning people not to click on e-mail attachments that could steal their banking details.
It's after a number of people on the Island were targeted by scammers this week.
The OFT says the e-mail looks helpful as the fraudsters say they've been sent people's personal details and ask them to open a document.
Chief inspector of Trading Standards John Peet says people need to be careful when opening emails:
