Pay attention or you could be booted off the Internet Monday.
Facebook is notifying users who have a certain type of malware on their computers and reminding users that if they don't remove it, they will lose internet access on July 9, when the FBI shuts down the malware.
The FBI's website also has a link that allows people to check if they have malware on their machines.
According to the FBI, DNS Changer malware can modify a computer's settings and possibly direct the computer to "improper results."
NOTE: The link announced in the video is incorrect. To see if your computer is infected, visit DCWG.org.
