My roommate works at an office with several employees, and their internet technology person said that there is a new, very nasty worm set to launch
on April 1. She has told me to shut down the computer this afternoon, totally.
I hope to get more information and post it before she tells me to shut down; she wants everything unplugged, even, under the IT person's advice. I assume she'll come up with some advice about what to do about it to protect our computers.
