In an ideal world, companies that profess to be dedicated to protecting users from malware and privacy threats probably shouldn't contribute to the problem. In the world we live in however, that's often not the case--as everybody saw when Facebook tried to sell its users on a "privacy protecting VPN" that actually hoovered up their browsing data, providing insight into user behavior when they aren't using Facebook. Facebook did ultimately shut the project down, but it took a year before they were willing to do so.

Enter antivirus and security firm Avast, which has been taking heat after it was discovered that the company's services are collecting user browsing data. Back in August, Wladimir Palant, the creator behind Adblock Plus, wrote a blog post detailing how Avast Online Security and Avast Secure Browser were covertly collecting the browsing data of the Czech company's 400 million users. In response earlier this month, both Opera and Mozilla pulled Avast extensions from their respective add on markets, though Google has lagged in any comparable response.
