G'Day Roland,
Unfortunately this is a common problem. And often, LOGic wares the blame from something completely beyond its control.
I have lost count of the number of "browsers" I have fixed for my friends. They do not realise what will happen, and have no foundation for understanding, what to "not tick", as they install software they really do want to install. It is usually days later that they see something in IE that has appeared from nowhere.
For example, if you have installed Java - try to avoid it - during the installation there is a dialogue that includes the ASK Search Toolbar for IE - it will be installed by default, unless you clear the selection during the Java installation. One has to wonder why Oracle has made an agreement with ASK to do that.
I increasingly see the practice in Open Source tools. Google Chrome is often added to the install, and unless the "tick" is removed, will be installed.
In 2014, just clicking quickly through installation dialogues, without paying attention, is no longer a good idea.
