The FBI is warning people to check their computers now for a potential virus or risk losing their internet this summer.
Investigators say international hackers used an online advertising scam to install malicious software on half a million computers around the world.
According to the FBI, most people won't even realize there's a problem with their computers... until July 9,when you won't be able to connect to the internet anymore.
The FBI is now urging people to visit a website run by its security partner to determine if your computer is infected. It also walks you through how to fix the problem.
