OK, the upsidedown h is actually the Greek letter µ from µTorrent. So you got µTorrent installed.
If you download a torrent, you should select "Open with …" and choose that µTorrent or uTorrent
It might help as well to go to the Start menu of Windows (the button bottom left of the Windows desktop) and to select there to open µTorrent. Then in Options > Preferences > General > Click on the button "Associate with .torrent files" if it isn't greyed out.
