McAfee should provide a full uninstall tool/pgm. that readily offers to uninstall *all* features. If none found, actually re-install McAfee again. Once done, reboot into "safe mode" and try that method to un-install.

Also, if you like report the trouble you're having to McAfee to see what action they take. If anything just the report to make them aware of issues.
I uninstalled a McAfee security center 2008 software from my computer. The personal firewall that still comes with the security center still stops some programs from accessing the internet. How do I stop this since the computer shows that the software has been uninstalled but my windows Security center tells me that some of the packages on the mcafee are still running.
n.b. I have stopped all mcafee services but still have that problem. I am using a Vista Home Premium.
