btdna.exe task purpose and description:

Btdna.exe is a file that would have been installed by you, it would not have arrived as preinstalled software. Always check the exact disk location which is shown to you below, to help verify the file is not spyware or virus related software. Spyware or virus writers often use similiar names and place files in other folders hoping to fool you into leaving their virus programs on your computer. This btdna.exe file is an executable program that would have arrived when you installed bittorrent. This file will run as a background task, and many report that even uninstalling does not remove it. If you installed bitttorent then you may leave this, but if you uninstalled bittorrent then you should kill this task and delete this file, as it should not be running the background. Although this file is considered safe, and is not virus or spyware related, you should always be carefull when running p2p software like BitTorrent, Limewire, Bearshare, Kazaa, etc., as these software programs can also exchange viruses if not used carefully. (See the details below for the actual location of this file.)

General information:
Be aware that many tasks will be similiar names to existing tasks or processes. You can always view the running tasks on your computer by pressing ctrl-alt-del to view the windows "task manager", and then view the "processes" tab. This will show you all tasks running or currently active on your PC. Although this shows you all running tasks, it does not show dll file thats are loaded, as they get loaded as part of other processes. Many spyware writers attempt to hide their files on your computer, for example, btdna.exe may be intentionally misspelled to look like a similiar task, or spyware may be named very similiar to a Windows system task. The reason they do this is so you cannot easily recognize the name in your tasklist as I have mentioned above. Make sure always check the location of the file if you are concerned. You can always find the location of btdna.exe on your computer by using your Windows search options, but I will also try to list the file location of every file described on this website, so you can verify the correct location.
