Also. most programs that are considered "malware", typically have no provision for uninstalling them. Since this is a torrent file, there is a greater than average chance that this might be malware of one type or another.

I would admonish you to refrain from downloading file from unknown sources, especially with a computer used for work or business purposes, since any given file may contain spyware designed to steal sensitive personal & financial data.
I would suggest those things, but that would just be "piling on", now wouldn't it?
However, at the very top of the "Introduce Yourself" forum, (which is THIS forum), there is this message; "DO NOT POST QUESTIONS in this forum, INTRODUCTIONS only", so it would appear that you are not really inclined to "look before you leap".
