completely remove wp-surveys

Hi I guess you are not supporting this anymaore, but I thought I might give it a try…
I am having some memory problems with a WP site and noticed that although WP-Surveys had been uninstalled, there are stil some of it’s tables left. Can I safely remove them? Can you think of any other settings or database entries to remove?

Thanks!
