The AVG Security Toolbar is a tool that works together with the LinkScanner component. This tool is available in all editions of AVG 2012. If you choose to install the toolbar during the installation of AVG, it will be added to Microsoft Internet Explorer and/or Mozilla Firefox.
We would like to inform you that if you are using an alternative Internet browser instead of Internet Explorer, (e.g Avant Browser) you may experience unexpected behavior.
More about AVG Security Toolbar features can be found in FAQ 4360.
