Lenovo on Friday said it will offer free subscriptions to Intel security software to customers who bought laptops that were shipped with a program known as "Superfish," which made PCs vulnerable to cyberattacks. Lenovo, the world's biggest personal computer maker, last week advised customers to uninstall the Superfish program.

Just over a week ago, the Superfish visual discovery software preloaded onto Lenovo consumer notebooks beginning in September 2014 created concern and frustration among our customers and the security and privacy communities.

Since then Lenovo has been working to create tools and update antivirus programs to eliminate Superfish software. And an automatic removal tool is available on Lenovo.com.

Lenovi will also offer Lenovo PC users affected by this issue a free 6-month subscription to McAfee LiveSafe service (or a 6-month extension for existing subscribers).

Lenovo plans to post information about all software that comes preload on its PCs that explains what each application does.
