It looks like versions 184.108.40.206 and later ask if you want some kind of toolbar, but they still install a bunch of other stuff without your permission. I tried installing version 220.127.116.11 a while back, and I canceled the installation because it looked like it was going to install OpenCandy adware. I've heard that other versions ask to install the Ask toolbar and still install the Conduit toolbar no matter what you do.
As for the original question, Windows 7 and recent versions of Mac OS include DVD creation software. If you don't have access to those operating systems, try the programs mentioned above.
I have not experienced this type of problem when doing the custom installation.
If you have these third party softwares installed you can use AdwCleaner to remove them.
An image like the one below will open, click on Scan.
Once the search is complete a list of the pending items will be displayed. If you see any which you do not want removed, remove the check mark next to it.
Click on Clean to remove the selected items.
You will receive a message telling you that all programs will be close so that the infections can be removed. Click on Ok.
When cleaning process is complete a log of what was removed will be presented. Please copy and the paste this log in your next post.
If you require further assistance I would suggest starting your own topic as this is detracting from the topic posted here and isn't fair to OEBD.
