Authorities are warning of a scam targeting E-ZPass users.
Customers are receiving fake emails claiming they have outstanding bills for unpaid tolls.
The messages ask potential victims to click on an attachment to pay.
But it's all a scheme to get access to your computer and your personal information.
A AAA spokesperson recently received one of the fake alerts and said it appeared very real.
"If you use an ez pass, you would probably think you've gone through a toll booth or toll plaza and your transponder didn't work," said John Townsend, AAA Mid-Atlantic Spokesman.
Security experts say you should avoid any emails with attachments or requests for personal information.
Also, take a closer look at the sender's email address.
It may say E-ZPass, but if you hover the mouse over it, the sender's real address will be revealed.
