Lol. Even Firefox did away with sidebar bookmarks by default. Why? More Real estate. You must be an IE lover stuck in the past.
@Aventador,Please stop trying to antagonize the person who started this topic.Like you Chrome is my default and chosen browser that however isn't everyone's choice.
It has for a long time been the practice of Avast to offer the Chrome browser, toolbar and more recently Chrome drive during
the install process. Using the custom method of installing avast! affords you the opportunity to uncheck the installation of the Chrome products.
If you inadvertantly missed the options, your only option is to uninstall what you didn't want.
