I don’t have a Lenove computer but I’ve noticed that If I go to amazon and start checking prices on a product, lets say running shoes, and check out several brands of running shoes when I’m finished and start going to other web sites I frequent I start seeing advertisements for running shoes virtually everywhere I go. This happens virtually every time I shop for a product on Amazon.
