That’s following the revelation that Lenovo shipped adware called Superfish on some of its notebook devices.
Lizard Squad claimed responsibility for downing the Sony site at the end of last year.
Lenovo managed to get its site up and running after people that went to its site were redirected to other web sites.
Lenovo has stopped including Superfish shipping on its machine and offered people that had encountered it a software fix to remove it.
Lizard Squad managed to use a vulnerability to Lenovo’s name registrar to divert people away from the Lenovo web site.
