Most of you are so lazy to click the custom option of installing any application on your PC.  This small laziness results in installation of toolbars, applications you never wanted.

Most of the good applications give you option to deselect any apps included in that particular bundle. But many of the apps dont even give you that option. Some of the installers install toolbar apps by default untill you untick them.

Here’s a compiled list of almost all the Apps that bundle something or the other with their installs. The list is reproduced here with a bit of editing from Calenderof updates forum.
