I heard that uTorrent was a good program for torrent files. I have never used it before and didn't know how it worked. So I went a downloaded it, and once it was finished I tried to open some torrent file i had on my computer(don't ask what it was because I don't remember). It never opened the file up so I closed it and noticed that most of my programs on my desktop had the image of the uTorrent logo. When I tried to open Internet Explorer it opened up uTorrent. I deleted uTorrent from the control panel and it made most of the icons on my desktop a blank paper, such as Internet Explorer. Once I tried to open up Internet Explorer it says "Choose the program you want to use to open this file:" and then the only option is Internet Explorer which obviously didn't work when I tried it. Please post it you have a solution to my problem. Thank you. P.S.: I am using Fire Fox
