Warnings have been going out for some time that an international hacking group slipped in some malware which would keep computer users from accessing the internet. The FBI discovered this issue and set up a temporary safety net to protect those whose computers are infected, but this safety net will go away on Monday.
Supposedly people with affected computers were notified on Facebook and Google and some internet providers, but not all. And not everyone who received a message may have paid attention to it because there are so many messages which themselves are bad news hacks.
The FBI has created a website which you can use to determine if you have the malware and ways to get rid of it. If you have it and don't get rid of it, on Monday you'll have no internet. I have no idea if we have this issue and it's daunting to think of trying to get rid of it.
