this talks about what files it installs so that may help you track it down.
Theoretically, this shouldn't be effecting your computer in the way that you think it is(though it may be a virus in disguise) there is a chance as well that this comes up because mcaffe can't get rid of the whole file so it may be an inactive ghost/ or a legitamit file that was installed as part of another program or process by an adminstrator.
I would suggest also running malwarebytes if you can. It may be more effective as a removal tool for the symtoms that you have. if you do find something with malwarebytes, post the log here that it removes and I will try to help you remove the rest.
