PNGs are usually not premultiplied (unassociated alpha). Fusion doesn't make any assumptions about alpha handling, though, unlike most other software, which hide this step from you. Add an AlphaMultiply node right after the Loader or MediaIn that holds the PNG, and it will probably work as you expect.
Oh, and if you want to make sure that a PNG exported from Fusion is rendered correctly in other software, put an AlphaDivide node right before sending it out. Otherwise it will probably get multiplied a second time, destroying any translucency and/or giving you dark fringes.
