Periodically McAfee Security Center will not open via a right click. A double left-click on the security center symbol in the system tray produces a balloon which says updates are being installed, and when this balloon is present, scheduled scans will not run.
When the balloon is present, there is no update or install activity occurring. It takes three restarts to get the McAfee symbol to react and get the security center to open and then the scheduled scan will finally run.
I am running Windows 7 on an HP4540s laptop and McAfee Security Center. I have McAfee updates set to “notify when updates are available”, so that I am aware when updates are downloaded and installing. I also have a scan scheduled every Monday morning.
This is a continuing problem that occurs at least once a week and has been this way for several months.
