Re: mmsshost.exe is using 77% of RAM

Hello again, as requested, the laptop has the following S/W installed:

McAfee® Total Protection

Version: 16.0

Release name: 16.0.R9

Re: mmsshost.exe is using 77% of RAM

Hi Did this issue ever get solved?  I just rebooted after a Windows Update and had the MMSSHost taking up the CPU.

Re: mmsshost.exe is using 77% of RAM

I should add that I am using LiveSafe and seeing that this problem has been around for months, I am seriously considering switching back to Norton.

Re: mmsshost.exe is using 77% of RAM

Is everyone updated to 16.0 R10 and seeing this problem? Please let me know

Re: mmsshost.exe is using 77% of RAM

Yeah, McAfee Internet Security  version 16.0 R10

Re: mmsshost.exe is using 77% of RAM

Yes, both the Home PC and my laptop have been upgraded to 16.0 R10 (between April 09 and 24 for some components). Checking daily the performance and currently no problem observed with the known issue.

Just for information, on the laptop, where I originally did report the ‘mmsshost’ issue, I decided last week to re-install completely the Win 10 S/W after that an issue was blocking some important updates (issue known and reported on the Microsoft Website). It has costed days to restore the laptop as I did not know that re-installing Win 10 would have an impact on many other applications that were also deleted from the laptop (no loss of personal data however)!

Starting with a fresh laptop/Win10 combination, I have then re-installed the McAfee Total Protection. For the second day by now, no ‘mmsshost’ issue has reoccurred yet. I will keep monitoring and reporting the status on this forum.

 

Re: mmsshost.exe is using 77% of RAM

To Selvan, I saw on an other forum link the following posting from P8888:

McAfee Support Community   Consumer   Web and Email Protection   LiveSafe   Windows update KB4088882 compatibility with McAfee...

 From: P8888 (Level 7) - 3 weeks ago !!

Windows update KB4088882 compatibility with McAfee LiveSafe

Microsoft released a Windows update: March 22, 2018—KB4088882 (Preview of Monthly Rollup). In the notes on this update it said the following; (Contact your antivirus manufacturer to verify that their software is compatible and that they have set the following REGKEY on the computer:

 Key="HKEY_LOCAL_MACHINE"Subkey="SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat"

 Value Name="cadca5fe-87d3-4b96-b7fb-a231484277cc"

 Type="REG_DWORD” , Data="0x00000000”).

 Is McAfee LiveSafe compatible with this Windows update? Thanks.

 My question: I personally have not seen any answer to this request. Would this be part of the Release 10 update? Why McAfee do not provide the customer the change that have been made in the new release?

Re: mmsshost.exe is using 77% of RAM

I deleted MMSSHOST, well actually closed it in Task Manager, then before it had time to restart itself i changed the explorer file to .old   ... 3 days of no problems, McAfee still detects and scans, still updates etc.  However noticed today that it has managed to replace the MMSSHOST.exe file with a new copy and trggered itself to start ... in doing so though, the blippy activity started again, running my CPU to 25% every minute and making video and audio files jitter !!

So, once again, i've stopped the file in Manager and deleted it in Explorer, take that McAfee !!

I bet this issue will take them as long to resolve as the Quick Clean issue took to resolve last year ... so i reckon a fix will come about by Christmas

Re: mmsshost.exe is using 77% of RAM

Has this issue been resolved? How do I fix it? I am on the verge of uninstalling because I can't use my computer. This just started for me just a couple of days ago, but it cannot continue. Please tell me what I need to do to stop this from taking over my computer every few minutes!

Original post 05-06-2018 01:34 PM:

I also do have the issue with the McAfee Management Service Host although not all the time but mos of the time. Especially on the moment when I interact with my notebook.

My mouse will become slow and the total CPU usage will go to 100%.

It is frustrating me for about a week now and I have no clue when and how the issue exactly started.

Notebook: Lenovo Ideapad 100-15IBY
Windows 10, build 1709
McAfee 16.0 R10

I hope the issue will be fixed soon.

I specifically registered to this forum today to be able to follow and react on this specific discussion.

Update 05-06-2018 10:48 PM:

I checked for Windows updates and appearantly the update Windows 10 build 1803 (Spinr Creators update) was ready to download and install. About 1 hour of downloading and preconfiguring the update and 1,5 hours configuring the update (it is a huge update appreantly!) later it seems the issue doesn't seem to appear again so far.

So my suggestion is to update Windows 10 to build 1803 (Spring Creators update) and check if the issue still occurs.
