Internet Explorer
Don't forget to check your Myspace!
Earlier yesterday, students checked their inboxes on Firefox, Chrome or Safari to find an email warning them to "Temporarily Discontinue Use of Internet Explorer," but really just reminding them that the browser didn't actually die in the early 2000s.

Apart from being so slow that you can’t even play 2048 properly, Internet Explorer also has a security flaw that could allow hackers to take over your computer and look at your emails (wait, doesn’t that sound familiar?).

So for those of you still living in 2005, you might want to avoid using Internet Explorer for a while (or forever) while the problem is fixed. And honestly, if Internet Explorer was your browser up until yesterday, you had problems already.
