Last night, Mastercard announced a virus had hit a business that handles Mastercard, Visa, Discover and American Express card transactions. Today, some Mastercard users will be relieved at the news that the company said just a fraction of almost fourteen million accounts were considered at high risk for possible fraud.

Mastercard now say sixty-eight thousand of its card holders are at higher levels of risk. This means they should look at their credit or debit accounts, but should not worry about identity theft.

The FBI says the security breach, in which the virus captures customer data for the purpose of fraud, could affect forty million people.
