Re: McAfee Management Service host - VERY HIGH CPU USAGE

I just started having this problem last night. This morning when I checked why my CPU fan kept running and saw McAfee maxing-out the CPU, I checked and found this forum. Here's what I did that seems to have resolved it:

  1. turned-off McAfee realtime scanning
  2. turned-off McAfee firewall
  3. checked for McAfee updates (even though it had said I was up-to-date, it did download and install an update.
  4. Shutdown the PC
  5. Started the PC

Since CPU usage went back to normal, I turned realtime scanning & firewall back on.  All is well.

Re: McAfee Management Service host - VERY HIGH CPU USAGE

In my previous mail I mentioned that I will publish the status of the Laptop after having used the tool provided by McAfee. Today, about a week, the issue has NOT poped-up again!

I monitor constantly the mmsshost.exe usage and it has not rised up to the sky like before. Is this a true working solution? I do not know but so far it continues to work. Will post a new status after a few days unless the issue reoccurs sooner.

Re: McAfee Management Service host - VERY HIGH CPU USAGE

Please check and let me know the McAfee Version and the Release Name on both the machines (one with the issue and one without the issue)

Below is how you can check the detals.

Open McAfee -> Go to Account ->  Open About

Re: McAfee Management Service host - VERY HIGH CPU USAGE

I had removed it from the other PC as the software kills the PC and its unusable.

I just reinstalled to check the version and its unusable when the software is running with +98% CPU usage for McAfee Management Service host

Both are Version 16.0

Release name 16.0 R8

The software is provided with Sky Broadband so is installed through a link to a download from their site.

both are using windows 10 OS fully updated

Re: McAfee Management Service host - VERY HIGH CPU USAGE

Hello 'tezhall', just for my personal information: are you saying that you downloaded the " SubDBFix.exe" tool and got some specific messages (or was that another link that you used, providing the following tools  like "MVT.exe" or "MCPR.exe" which by the way did not work for me)?

Did you actually download it, ran it and then on or during execution got a message? or just did he not run at all?

Sorry if this a bit complex but I just try to understand all options in case the issue would re-appear on my Laptop,

Thanks

Re: McAfee Management Service host - VERY HIGH CPU USAGE

I am getting the same issue where the McAfee Module Core Service is taking upwards of 2400 MB of Memory and CPU fluctuating up to 40%. I cannot use my computer as it is taking all resources. My choice is for you to tell me how to fix in the next few hours or I remove remove and request a refund as I have just purchased this in last month after moving from Norton.

Re: McAfee Management Service host - VERY HIGH CPU USAGE

I had the same problem this morning after installing a raft of Win 10 and Office updates last night. For perhaps 20 minutes McAfee Management Service Host was stealing 97-100% of CPU and fan was racing trying to cool everything down. I tried putting computer (Dell Vostro laptop w/ i5 running 8GB) in sleep mode, but problem persisted. Rather than wait the 10 min to try power-down solution, I instead went to Task Manager and right-clicked  "End Task" on the offending task. After about 5 "End Task" requests,  CPU and disk usage dropped off, and the CPU fan calmed down. 

What's interesting is thatMcAfee Total Protection kept running with all features -- I was able to selectively scan files and "Secure" and "Web Advisor", Firewall, RealTime Scanning, etc all kept running. Now, 20 minutes later, with several apps running everything's still behaving -- including McAfee Management Service Host, which apparently never stopped running, or came back to life spontaneously!

Seems there's a bug somewhere in McAfee software that prevents MMSSHOST.exe from relaxing once it's done whatever job it needs to do on start-up. 

We'll see what happens when I shut down the computer -- but that could be quite a while, as my old Vostro is surprisingky happy with Win 10 Pro...
