comcastau.dll file purpose and description:

ComcastAu.dll is a program which was most likely installed by you, as this would not have arrived as preinstalled software also. The actual disk and folder location is also listed below, always verify where its located on your hard drive, as this makes sure it is not spyware or adware simply placed elsewhere on your computer, and using the same name in an attempt to fool you. This ComcastAu.dll DLL program comes from internet provider Comcast, and is a free toolbar that will run in your Internet Explorer browser as a BHO software program. This is part of the searching and email toolbar they give away free. Personally I don't see any use for this type of stuff, but if you like it then feel free to keep it. If you have this then you also have comcastdx.dll. This ComcastAu.dll module is considered safe, and is not virus, adware, or spyware related.

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, comcastau.dll 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 comcastau.dll 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.
