To get rid of right-clicks on the Explorer menu, search the Windows System Registry for a substring of the text that appears in that menu. It will be under the "Shell" entry, most likely in more than one place. Delete those entries and you should be golden.

I'll contact Lavasoft about this faily new kind (to me anyway) of spyware/adware.
