Have you recently uninstalled McAfee?
If so are you using an alternative?
In the Services tab, I have 4 McAfee entries:
I *don't* disable any of them as I run both Mcafee Firewall and McAfee anti-virus.
Do you have similar entries?
If so I *wouldn't* recommend disabling them *if* you are actually using McAfee.
If you are using McAfee, then have you tried uninstalling it, rebooting and installing it again to see if that can correct the error?
