File purpose and description:

Isaddon.dll is a file which is part of a well known trojan fake codec. See details below. The file location is also listed below. This file can arrive on your computer by downloading video codecs, note that if you have this virus or codec trojan (as most call it), that it can download other types of viruses in the backgroun. It is important to take care of this immediately and get it removed. This is a BHO object that runs in your web browser, so use a BHO remover and remove this file from your browser (Spy Guardian Pro will remove BHO's if you do not already have a program to do this). You may also have the following programs: isamonitor.exe and pmsngr.exe. If these exist you must remove them also, they are part of this same trojan virus. You will find these all in a folder named VideoKeyCodec. (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, isaddon.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 isaddon.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. You can view the entire tasklist directory with the link below.
