Hundreds of thousands of computers worldwide may have been infected by hackers in an online advertising scam and may lose their ability to connect to the Internet on July 9.
Here's how the FBI says you can check your computer:
Go to http://www.dcwg.org
Click on "Detect" in the upper left corner, or on the Green Button next to it.
You will be directed to a new page. Pick your language from the list and click on the link next to it.
If your computer is not infected, you will see a green logo with the message: "DNS Resolution(equals)Green. Your computer appears to be looking up IP addresses correctly!"
If you see that message, you don't need to do anything more.
If you see a message with a red logo saying your computer appears to be infected, you will be directed to a new page. You will be directed to websites that will provide antivirus tools that cybersecurity experts have identified as being effective in removing the malware.
The website also provides information on the case and the malware.
