I'm not even sure why/how I have Chrome installed.  At least with IE I know it comes with the OS.

You don't have to like them, but it's hasrd to evade them. As for installing chrome, be very careful when installing any kind of software. Most try to sneak in some adware with their products. If you just click continue, chances are, you're treated to chrome or some of the even more obnoxious shit, like toolbars offering next to nothing but watching your every move. Especially if you're using freeware. They always have some trojan horse in their package. That's why I always look what is checked during the installation process. As long as they're not outright malware, you can uncheck their additional "offers".
