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.

* Important Terms and Offer Details:

  Subscription, Free Trial, Pricing and Automatic Renewal Terms:

  • The amount you are charged upon purchase is the price of the first term of your subscription. The length of your first term depends on your purchase selection (e.g. 1 month or 1 year).  Once your first term is expired, your subscription will be automatically renewed on an annual basis (with the exception of monthly subscriptions, which will renew monthly) and you will be charged the renewal subscription price in effect at the time of your renewal, until you cancel (Vermont residents must opt-in to auto-renewal.)
  • Unless otherwise stated, if a savings amount is shown, it describes the difference between the introductory first term price (available only to customers without an existing McAfee subscription) and the renewal subscription price (e.g., first term price vs. each year thereafter).
  • Pricing is subject to change. If the renewal price changes, we will notify you in advance so you always know what’s going on.
  • You can cancel your subscription or change your auto-renewal settings any time after purchase from your My Account page. To learn more, click here.
  • You may request a refund by contacting Customer Support within 30 days of initial purchase or within 60 days of automatic renewal (for 1 year terms or longer).
  • Your subscription is subject to our License Agreement and Privacy Notice. Subscriptions covering "all" devices are limited to supported devices that you own. Product features may be added, changed or removed during the subscription term.  Not all features may be available on all devices.  See System Requirements for additional information.
  • Free Trial Terms: At the end of your trial period you will be charged $39.99 for the first term. After the first term, you will be automatically renewed at the renewal price (currently $124.99/yr). We will charge you 7-days before renewal. You can cancel at any time before you are charged. ​

 **Free Benefits With Auto-Renewal:

  • For many qualifying product subscriptions McAfee offers additional benefits for free when you are enrolled in auto-renewal. You can check your eligibility for these benefits in your My Account page. Not all benefits are offered in all locations or for all product subscriptions.  System Requirements apply.   Turning off auto-renewal terminates your eligibility for these additional benefits. 
  • Virus Protection Pledge (VPP): If we cannot remove a virus from your supported device we’ll refund you the amount you paid for your current term subscription.  The refund does not apply to any damage or loss caused by a virus.  You are responsible for backing up your data to prevent data loss. See terms here: mcafee.com/pledge.
  • Safe Connect VPN:  You will receive free, unlimited access to our VPN wireless on supported devices. Users not on auto-renewal have access to 500 MB/month of bandwidth.

   ‡Additional Terms Specific to Identity Monitoring Service:

  • Eligibility: McAfee® Identity Monitoring Service Essentials is available within active McAfee Total Protection and McAfee LiveSafe subscriptions with identity monitoring for up to 10 unique emails. Phone number monitoring is enabled upon activation of Automatic Renewal. Not all identity monitoring elements are available in all countries. See Product Terms of Service for more information. 
  • Your subscription is subject to our License Agreement and Privacy Notice. Product features may be added, changed or removed during the subscription term. Some features may require registration and a valid ID number to activate. See System Requirements for additional information.
  • While McAfee Identity Monitoring Service provides you tools and resources to protect yourself from identity theft, no identity can be completely secure.
  • US Only:
    Fair Credit Reporting Act: You have numerous rights under the FCRA, including the right to dispute inaccurate information in your credit report(s). Consumer reporting agencies are required to investigate and respond to your dispute, but are not obligated to change or remove accurate information that is reported in compliance with applicable law. While this plan can provide you assistance in filing a dispute, the FCRA allows you to file a dispute for free with a consumer reporting agency without the assistance of a third party.
  • Identity theft coverage is not available in New York due to regulatory requirements.
