When downloaded it finds and modifies files that other web browsers would never touch. It has a tendency to break expensive applications and destroy ever-so-precious files. It cannot render pages designed for browsers other than itself and it is big, clunky and looks like shit. It was once a good browser but M$ decided to abuse its power and force everyone that buys Windoze
to use it as a file browser (Windoze Explorer) and a web browser. It is like an ugly weed; once it has sprouted and grown it can never be truly killed because you always leave a small root that will grow back into the ugly weed.
