Hey, folks! So, you might've heard about this virus/malware thing happening on Monday.
Long story-short: a while ago some greedy people created malware that would direct people's computers to websites (that were basically commercials)...they got paid for each time a computer was redirected. Now the F.B.I. is shutting down these websites, by doing so computers with the malware will be blocked by going on the 'web.
If you have an Apple, you're all good.
If you own a PC and aren't sure if your machine has been infected, you can visit this 'site to get a definite answer on whether you'll be good to go on Monday.
