I don't want to remove it if it's doing no wrong.
Seems to me that something you install on purpose isn't spyware. Especially if it does no harm.
To be technically correct, weatherbug is adware, extremly badly written adware that causes crashing and lockups. Some versions have been worse than others.
Some early versions may have been allowing backplane installation of other ad and malware, and they have since, supposedly, cleaned up their act.
Intellicast has a similar application with no adware AFAIK.
