Lenovo Installed Hijacking Adware On PCs

Tuesday, March 3rd, 2015 by | Filed Under: Security Help

Computer manufacturer Lenovo apologized to its customers and admitted that the company “messed up” by installing a shopping software called Superfish that inserts advertising onto your browser on several models of their laptops.

Many computers come with sometimes unwelcome pre-installed software, also known as bloatware. Developers pay the manufacturer to be installed on the computers and the manufacturer, in turn, lowers the price of the device. But, Superfish has a key difference. It also installs a certificate into Windows that takes over SSL certificates from security sites that could permit hackers to steal your information. Simply uninstalling Superfish does not remove the security certificate.


According to Lenovo, Superfish may be found on the following models.

G Series: G410, G510, G710, G40-70, G50-70, G40-30, G50-30, G40-45, G50-45, G40-80
U Series: U330P, U430P, U330Touch, U430Touch, U530Touch 
Y Series: Y430P, Y40-70, Y5leno0-70, Y40-80, Y70-70
Z Series: Z40-75, Z50-75, Z40-70, Z50-70, Z70-80
S Series: S310, S410, S40-70, S415, S415Touch, S435, S20-30, S20-30Touch
Flex Series: Flex2 14D, Flex2 15D, Flex2 14, Flex2 15, Flex2 Pro, Flex 10
MIIX Series: MIIX2-8, MIIX2-10, MIIX2-11, MIIX 3 1030
YOGA Series: YOGA2Pro-13, YOGA2-13, YOGA2-11, YOGA3 Pro
E Series: E10-30
Edge Series: Edge 15

The company says it stopped preloading the software onto its models in January. They’ve made a tool for uninstalling the software available and you can find it by clicking here.


Microsoft has issued an update to Windows Defender that deletes Superfish and also erases the security certificate generated by the program and  McAfee and Symantec have also updated to disable this function.

Lenovo pointed out that choosing to users have a choice whether or not to use Superfish, but as is often the case with pre-installed software, many people just click “OK.”

If you have one of the Lenovo models mentioned above, make sure to check for the latest updates to your security program, if it’s not already set for automatic updates.

    I wonder whether legal action had been intiated against the offending software developer!

  2. […] Computer manufacturer Lenovo is under fire again- accused of using what many consider to be a pretty-shady tactic on its PCs.  You’ll recall that they took heavy criticism earlier in the year for installing SuperFish, a form of adware that can hijack your searches, on its PCs. […]
