Do you have a retail computer made by Lenovo? Did you buy your Lenovo at a local store? If so you most likely have some bad software installed and it was installed by Lenovo. Here is their statement regarding the issue:
LENOVO STATEMENT ON SUPERFISH
Dear Valued Partner,
As you may have heard, select Lenovo consumer notebooks shipped after September 2014 included Superfish Visual Discovery software as a shopping aid to customers. Superfish is a TrustE certified third-party software vendor, with offices in Palo Alto, CA.
User feedback on the software was not positive and we received some reports of security concerns.
Please note that Lenovo has NOT loaded this software on any ThinkPad notebooks, nor any desktops, tablets, workstations, servers or smartphones. The only impacted models are the following consumer notebook series: Z-series, Y-Series, U-Series, G-Series, S-Series, Flex-Series, Yoga, Miix and E-Series. If you use any of these Lenovo consumer models in your enterprise, please refer to the Customer Support information below.
While this software does not impact the models typically used by businesses, we wanted to let you know that we take user feedback seriously at Lenovo. We know that millions of people rely on our devices every day, and it is our responsibility to deliver quality, reliability, innovation and security to each and every customer. We make every effort to provide a great user experience for our customers.
We recognize that the Superfish software has caused concern. Lenovo has taken steps to address that concern.
• Superfish has completely disabled server side interactions (since January) on all Lenovo products so that the software is no longer active.
• Lenovo has stopped preloading the software and will not preload this software again in the future.
• Lenovo has provided instructions for uninstalling this software and will soon provide a software removal patch.

We appreciate your confidence in Lenovo.
