Pay attention to your computer, or you could be booted off the internet Monday.
Facebook is notifying users who have a certain type of malware on their computers.
If you don't remove it, you'll lose internet access on next Monday, July ninth.
That's when the F.B.I. shuts down the malware.
If a user accesses Facebook from a computer infected with d-n-s-changer malware, the site will display an alert, with a link to a website that instructs users on how to remove the malware.
The F.B.I.'s website also has a link that allows people to check if they have malware on their machines.
According to the F.B.I., D.N.S. changer malware can modify a computer's settings and possibly direct the computer to "improper results."
