You don't have to activate McAfee in order to uninstall it.
I do suggest that instead of using Windows Add Remove programs, you download and install the free version of Revo Uninstaller.
For best results, use Advanced. If successful, and asked for a reboot, say no.
Then click Next to begin looking for leftover items. Check only the bold entries.
To make sure you get everything, if any entries-usually the last thing listed and not in bold-have a + sign click on the + until you see more bolded items. Check those items to delete, then delete them. Click next and let it find files you can safely delete.
If a reboot was required, do so after deleting files and folders.
After booting back up, run the McAfee removal tool.
