"Yahoo" in IE help

[Comixion]

How can I disable "popular suggestions search" in the Yahoo search bar?

[yahooadam]

if its anything like the Google toolbar (which is IMO, miles better then the competition)

Go to Settings -> Options
"Search Box Settings"
"Suggest Popular Searches" -> uncheck it

Now that's for the Google toolbar, so you might need to adjust that for your yahoo one
