LEE COUNTY, Fla. - A warning to check what you click before you ship.  As people start mailing holiday packages, scammers are sending fake e-mails, pretending to be from the U.S. Post Office.  It's all an attempt to hijack your personal information.

A Lee County man called the Lee County Sheriff's Office when he got a suspicious e-mail supposedly from the U.S. Post Office.  He thought the claims in the e-mail were bogus and it turns out he was right.  The e-mail had a link with a virus.

Here is what to look for:

The e-mail has fake information about a package, online postage charges or bogus addresses.  Also, it gives you instructions how to print your own label and if you notice bad grammar and spelling, that is a red flag.

"That label, just like the USPS legitimate one, also had a click here and the legitimate label has that one as well.  So basically the consumer needs to be aware of receiving an email that they didn't solicit with instructions to click on something," said Beth Schell, Lee County Sheriff's Office.

The problem is, when you click on the link or attachment, a virus is installed that can steal your personal information like usernames, passwords and financial information from your computer.

If you think you've gotten one of these e-mails and you're a victim, call the Lee County Sheriff's Office Fraud Line at (239) 477-1242 and www.ic3.gov to report this or any other online scam or fraud.
