Its been known for many years that OEM PC manufactures pollute their PCs with burdensome software add-ons but this takes the cake.
If you purchased a new Lenovo PC from June 2014 through January 2015, there's a good chance you have malware preinstalled by Lenovo. It's called Superfish and could open your PC to other hackers and more malware. Lenovo claims the software was loaded to "Consumer Grade" (read: cheap) PCs but it's been found on Lenovo Y50, Z40, Z50, G50 and Yoga 2 Pro laptops as well.
Lenovo spins the software as "technology that helps users find and discover products visually". What is does is force feed advertising on sites you visit including banking and secure sites by creating its own Trusted Certificates.

Thanks, Ken. I inherited Anja's Lenovo Thinkpad, but it appears to be from back before the problem existed. Both my computers tested okay.
Run Malwarebytes, get the free version from Download.com. It is very good at keeping your computer spyware free. Just don't turn on the trial version.
Most all of the manufacturers do this now. It is how they can afford to sell $250 laptops. Welcome to the new world of technology.

That's why I buy the laptop immediately format the hard-drive and install Ubuntu. No malware and its free if you choose to be frugal but I usually send them $10.
What do you mean by "No malware"?
Are you so na´ve to think there's no malware out there for Macs or Unix/Linux based OSs? There's more holes in it than Windows according to the number of tracked security patches. They are the most currently attacked targets since Norton of the 90s.
When someone says it's impossible, that's all some people need to prove you wrong.
Oh, I forgot to mention; They're finding more software that may be worse than SuperFish. Turns out PrivDog is another. I'm waiting for Google Toolbar, Chrome and Firefox to be added to the list.
