April Fool

So today the blue screen came up when I signed on... and this strange blue page told me that my computer couldn't start... and I needed to do a restore... something didn't look just right about that... so I shut it off and brought it back up and clicked to start windows as I regularly did... in a few minutes I was doing business.... only I cannot get on facebook... everything else is okay... Anyone else got this today???? I remember reading something about some hacker group was going to do a huge group April Fools thing... anybody know what's going on... ?? Let's see if this can post. I have my malware running now checking all my files...
