Sears.com is distributing spyware that tracks all your Internet usage - including banking logins, email, and all other forms of Internet usage - all in the name of "community participation."
Every website visitor that joins the Sears community installs software that acts as a proxy to every web transaction made on the compromised computer. In other words, if you have installed Sears software ("the proxy") on your system, all data transmitted to and from your system will be intercepted.
