The Brand Lenovo Deployed Malware By Default

It's not just national intelligence agencies that break your https security through man-in-the-middle attacks. Corporations do it, too. For the past few months, Lenovo PCs have shipped with an adware app called Superfish that man-in-the-middles TLS connections.
Here's how it works, and here's how to get rid of it.
And you should get rid of it, not merely because it's nasty adware. It's a security risk. Someone with the password -- here it is, cracked -- can perform a man-in-the-middle attack on your security as well.
Since the story broke, Lenovo completely misunderstood the problem, turned off the app, and is now removing it from its computers.
