For those of you who are curious how you got the Yahoo Toolbar on your PC without your knowledge, seems many of the Adobe/Macromedia products (Reader, Flash, etc) 'offer' to install the yahoo toolbar for you while you're installing the program you intended to install.
This is usually a very small checkbox somewhere...very annoying, and very low-class if you ask me. In my case it also seemed to conflict with the Google Toolbar (which, UNLIKE the yahoo toolbar, is Very Cool). It's really distressing to me to note that this issue with the Yahoo toolbar still exists over a YEAR after the problem first showed up...
Anyway, it's great that there are communities like this out here. Thanks!
