There’s a very super serious absolutely critical patch for Internet Explorer that you need to download right away. I usually (never?) blog about this type of thing, but this exploit is a rather serious exploit (they disabled Internet Explorer on all of our campus computers, which they’ve never done before). Anyway, Microsoft issued a patch today and I’m pleading with you to go and download it:
If you already use Firefox or Chrome, you still should install the patch, just in case.
If you’re using a Mac, you’re okay and don’t need to do anything.
