Re: McAfee Management Service host - VERY HIGH CPU USAGE

Hello, I just wanted to share my personal experience with this issue. What seems to cause this issue for me is my internet browser. I use Opera as my default browser and I have lots of tabs open in it, (on average between 20-50). Typically everything operates just fine but after some time, could be a few days, weeks, or a month the McAfee Management Service starts over utilizing the CPU.

If I close my browser when this happens, CPU utilization by this process drops back to normal and the performance of my system is recovered. No reboot required in this case. I can reopen my browser and everything works like normal again. I would probably investigate if this same experience is true for others as well.

Re: McAfee Management Service host - VERY HIGH CPU USAGE

yes, my experience too has been that this ties in to Opera. I keep the task manager always running, and look occasionally for the solid blue square to show something is in runaway. If I see the solid blue circle I restart Opera, and McAfee returns to normal. I think it is related to some sites that continuously stream video, but not sure - my next step will be to see if I can tie it to a specific Opera window.
