This week has been one that Lenovo would love to forget after it was discovered that software they were loading onto laptops opened a huge security hole in Windows. The adware, called Superfish, placed its own security certificate on your machine and intercepted encrypted traffic to inject advertisements, also known as a man-in-the-middle attack.
That's the bad news and Lenovo is trying to backtrack and repair its brand image as the company has taken a serious reputation blow following this incident. Because of the nature of what Superfish did, it is a security threat to Windows and this is where Microsoft has stepped in.
Microsoft has pushed out an update to Windows Defender that kills Superfish. As you can see in the image at the top of this post, Windows Defender is removing the Superfish certificate and frying it like the piece of Carp that it is.
