Security firm AVG can sell search and browser history data to advertisers in order to "make money" from its free antivirus software, a change to its privacy policy has confirmed. The updated policy explained that AVG was allowed to collect "non-personal data", which could then be sold to third parties. The new privacy policy comes into effect on 15 October, but AVG explained that the ability to collect search history data had also been included in previous privacy policies, albeit with different wording.
