Anti virus - One of the most popular browser-based solutions for Internet security might be more dangerous than not having any security at all. According to a bug report filed by a Googleemployee on December 15th, the AVG Web TuneUp extension is disabling web security on Chrome for over 9 million users.
As gHacks explains, AVG’s extension was always problematic. It changes startup settings that might negatively affect a given user’s experience with the Chrome browser, it’s nearly impossible to change any modified settings without disabling the extension altogether and its privacy policy states that AVG can collect and sell non-identifiable user data to third parties.
