Should you want to remove Tribler 0.00 from your machine (I'm not being rude that is what it calls itself) may I recommend Cleanapp...
Seriously, this isn't a serious program. As you turn it on for the first time, notice how it forces you to save downloads to Desktop. One of those people who just keeps their desktop completely clear and actually locks it because you have your downloads kept somewhere else? Yeah? Well tough. There they must go, otherwise you will endure a python error and a forced exit. But surely there must be some way that once you grant the app this access, avoiding said Python error, surely then you can go in and change the download location to one of your choosing, right? Wrongamundo dudo!
To me this just seems like some sort of antediluvian P2P system that was around until everyone started using Napster in the late 1990's - until we see *encryption* and widespread take-up what is the point of this? You too will probably be asking yourself this question, if you can be bothered too.
Maybe check back here later to see whether they've actually made this the tool people would actually want.
