to answer your question in this forum too:

The McAfee Internet Security Suite 7 installs each program as a separate item in the Windows Control Panel Add/Remove Programs applet. Therefore, to uninstall the entire suite, it will be necessary to uninstall each of the individual programs.
Note: The McAfee SecurityCenter must be uninstalled last, since it will not remove if any of the other McAfee programs are detected.

1. Click on Start.
2. Click on Settings (skip this step if you are running Windows XP).
3. Click on Control Panel.
4. Once the Control Panel has appeared, double-click on the Add/Remove Programs icon.
5. Remove each of the following products one at a time, rebooting the computer when prompted:
   • McAfee Privacy Service
   • McAfee Personal Firewall Plus
   • McAfee SpamKiller
   • McAfee VirusScan
   • McAfee SecurityCenter

Scottatah-

If the only feature of McAfee which I chose to retain is the virus scan (Privacy service and firewall have been previously uninstalled), then should the security center be uninstalled?  Reason I ask is, since uninstalling privacy service and virus scan, I have reinstalled virus scan only and cannot access IE or my email service provider (MSN) unless I first reboot, which is OK, but inconvenient.  Short question is:  Does the virus scan alone feature require the security center?  Should i uninstall both and reinstall virus scan only?  Does security center automatically load with ANY feature of McAfee? I've written to McAfee tech support, but rec'd no response.
