'Facebook, Google and more than a thousand other companies collect data about you online. Until now there has been no easy way to understand and control data collection. AVG PrivacyFix checks your privacy exposure on Facebook, Google and LinkedIn, and with one click, takes you to settings where you can fix it. Block over 1,200 trackers from following your movements online. See which websites reserve the right to sell your personal data and easily request that they delete what they hold on you. Get alerted to privacy risks as you visit sites and know when policies change.

And because we no longer live our digital lives just on a PC, you can download the apps and manage your privacy on your mobile and tablet too.'
