AVG Official Blog: “All the latest versions of the major browsers today include do-not-track user preference controls, but these merely express your wishes. Many third-party sites will honor your request, but many don’t. And they only let you decide whether you want to block online tracking or not. AVG offers a do-not-track feature in its AVG Anti-Virus Free Edition. AVG takes it a step further by allowing you to customize your blocking preferences at a granular level. Permanent Identifiers – One company to be aware of is BlueCava. Unlike cookies, which can be blocked or removed, BlueCava provides tracking technology that allows sites to permanently identify whatever device you’re using to connect to the web. The good news is, you can opt-out by going to http://www.bluecava.com/preferences, but you have to connect using each device you want to remove from their system.”
