"I found this regarding Mcafee Virus Scan 8.5 : How to disable McAfee Virusscan 8.5?.
I hope it's relevant to your McAfee product:

By default, the copy of Mcafee Virus
Scan 8.5 comes configured to prevent
Virus Scan services from being
stopped. This is a safeguard against
viruses stopping McAfee services and
disabling Virus Scan. However, this
also causes the ""Disable On-Access
Scan"" menu item to be grayed out when
right-clicking on the VShield icon in
the system tray.

To turn this feature off and enable
the menu item:


Download and install the latest version of Virus Scan 8.5 over your
current version.
Right click on the VShield icon in the system tray and choose ""Virus Scan
Console"".
Right click the entry for ""Access Protection"" and choose ""Properties"".
Uncheck the option for ""Prevent McAfee services from being stopped""
and click OK.
The ""Disable On-Access Scan"" menu item should now be accessible when
right-clicking the VShield icon.


The latest version of Virus Scan 8.5
is necessary because it resolves a bug
that prevents the menu item from being
enabled even though the above option
is turned off."

So McAfee has a protection engine which prevent editing of registry, deleting of files and stopping of services.

Ensure that you have Administrators rights over the system.

Enter the system in Safe mode and then disable the startup of all McAfee services. It is possible to delete all system files of McAfee as well.

I was having serious performance issues with McAffee. I renamed McShield.exe to McShield.ex. That booger hasn't bothered me since.
