LOS ANGELES (CBS) — The FBI says a new computer virus could interrupt Internet service for hundreds of thousands of computer users this summer.

Agents say they’ve caught the hackers responsible for the DNS Changer virus, but a temporary solution keeping infected machines online will go away in July.

The FBI is urging computer users to check their machines for the Trojan malware, which can affect both Windows and Mac systems.

Linux, iPhone, iPad and Android devices, however, cannot be affected by the virus, which redirects users to servers controlled by cyber criminals.

To see if your computer is at risk, visit the DNS Changer Working Group or the FBI.
