Google Chrome finally gets a security feature which notifies user about extensions installed by third-party software on your Computer and Chrome disables them until user acknowledges it. Feature has been landed on Chromium build which may take few months to available for Chrome stable version. Antiviruses like AVG, Avast and other third-party programs install their extensions to browsers like Firefox, Chrome and Internet Explorer without user consent.

Mozilla has sorted out this for their users with Firefox 8 +release onwards which now automatically disables add-ons installed by programs outside browser, user can enable them if they want by visiting Add-ons Manager. Chrome left behind Firefox in this regard, recently lot of users started reporting an extension installed without their permission, malware can use this flaw.
