Postal customers who have received bogus emails about a package delivery or online postage charges are being instructed by the U.S. Postal Inspection Service to delete them.

The emails contain a link or attachment that, when opened, installs a malicious virus that can steal personal information from a user's computer.

The emails claim to be from the U.S. Postal Service and contain fraudulent information about an attempted or intercepted package delivery or online postage charges. The emails instruct the recipients to click on a link to open the attachment or print the label. Postal inspectors are warning the public not to click on the link, and instead simply delete the message without taking any further action.

Like most viruses sent by email, clicking on the link or opening the attachment will activate a virus that can steal information such as user names, passwords and financial account information.

The Postal Inspection Service is working to resolve the issue and shut down the malicious program.
