Lenovo had come under fire from security researchers who said earlier on Thursday the company pre-installed a virus-like software from a company called Superfish on consumer laptops that hijacked web connections and allowed them to be spied upon.
Users reported as early as last June that a programme, also called Superfish, was 'adware', or software that automatically displays adverts.
Superfish will no longer be pre-installed and has been disabled on all products in the market since January, when Lenovo also stopped pre-installing the software, said a Lenovo spokesman in an email to Reuters on Thursday. Superfish was included on some consumer notebooks shipped between September and December, he said.
"We have thoroughly investigated this technology and do not find any evidence to substantiate security concerns," the spokesman said.

Superfish "does not profile nor monitor user behavior. It does not record user information. It does not know who the user is. Users are not tracked nor re-targeted... The relationship with Superfish is not financially significant."
