Hm I use "spybot search and destroy" (not spyware S+D) and its completely free you can donate but they don't charge anyting to remove spyware.

As for Adware (the free version now seems to be called Ad-Aware) There is a free version for private use and I think there is a pay version for businesses and possibly extra features in the personal version.
You shoul not have to pay are you sure you downloaded spyBOT S+D and Ad-Aware SE?
