It is what the virus industry calls a false positive. There is nothing wrong with Add/Remove Pro. My guess is that it is because Add/Remove Pro is an older program. There is not much you can do to avoid this. You can report it to Mcafee if Mcafee has a place to report false positives.
This problem first showed up in four lesser known antivirus programs many years ago. Back in those days I reported it to them all and only one company wrote back and confirmed that after testing Add/Remove Pro that Add/Remove Pro was clean and that they would correct their software. The other companies evidently did not test Add/Remove Pro or correct their software.
Add/Remove Pro is safe to use.
