Why would you install Rapport when you already have security software which you could easily augment with a free anti-malware application such as Malwarebytes for instance?
If using extra anti-malware always use the free version and do not turn on any active protection, if offered, as that will interfere with McAfee and cause symptoms such as this. There are some minor exceptions, but that is a good rule to follow.
Rapport, although I'm not familiar with it, is known to cause major issues, not just with McAfee security, from what I can gather using the forum & web search for that name.
Does the problem go away if you uninstall Rapport? If so I suggest dropping it altogether.
EDIT: By the way, you posted in Business...is this Enterprise or the home products you are using? The same argument applies, I just want to make sure this thread is in the right area.
