Software that tries to install different software

Sometimes Always when you install software, no matter what software these days, there is a section to be found in the wizard where the software is trying to install a completely different program on your computer.
For example, you're installing a virus scanner, and the install is trying to include irrelevant browser toolbars as well. Or wants to change your homepage.

You can deselect the checkbox to prevent these kind of installs, but really, I remember a time where you could just click "next" on everything, without ending up with 15 toolbars raping my browser view and 12 useless shortcuts on your desktop for random software you didn't ask for.

My eye is trained to spot bullshit like this now, but it still baffles me to why this is still being done to people. No one wants this software; so the only people who end up downloading it are the people who missed the note, as it's often shown in a font that's 4 times smaller, or the by people who think they have to install it, otherwise the general install won't continue.
Because that's another thing some of these install wizards like to do: Blackmail you. "You need to install this, otherwise the installation cannot continue". And it's never been true.
