I read an article (about that Tor underground raid)) in that articel they said that installing the Tor browser bundle could be dangerous as it acts also as an relay and that illegal data could be streamed by my PC.
But as far as I know the browser bundle only installs a new Firefox browser with Tor addon.
I talk about the offical bundle from there: https://www.torproject.org/download/download-easy.html.en)
But now I feel a little unsafe...
Does anyone have more informations on this? And how can I make sure that there isn't a relay active?
