SAN ANTONIO -- Tens or even hundreds of thousands of computer users could be unable to get online this summer.
The FBI is warning all computer owners to check for a type of malware called "DNS Changer." PCs infected with DNS Changer, which is similar to a virus, were used by a group of hackers for fraud. Federal agents say they caught those responsible. But a temporary solution keeping the infected machines online will go away in July, and users won't be able to connect to the internet.Click on the following links to check your computer:DNS Changer Working GroupFBI Check Site
