Re: mmsshost.exe is using 77% of RAM

The reason why any progress weren't made as it seems that no logs were sent to McAfee for inspection. It would be great if you and I can help and not blame on them for not doing anything. If they persist in not servicing after sending logs, then I will just recommend get another AV software.

Re: mmsshost.exe is using 77% of RAM

I have the same issues for my laptop, please i need help asap.

Re: mmsshost.exe is using 77% of RAM

I now have this problem as welll.  It started after I rebooted (from off not sleep).  System details are:

McAfee Total Protection

Version: 16.0.5

McAfee SecurityCenter

Version 16.5

Build: 16.5.190

Affid: 1311

Languate en-gb

last update 21/11/2017


Version 20.5

Build 20.5.179

Engine version 3211.0

Personal Firewall
Version 17.5

Build 17.5.145


Version 4.0



Version 16.5

Build 16.5.181

Windows 10 Home

Version 1709

Build 16299.125

CPU usage is over 80 and usually around 90%, due to McAfee Management Service:

I am uninstalling and reinstalling McAfee and will re-post once I have seen if that works.

Re: mmsshost.exe is using 77% of RAM

Reinstall appears to have worked for me - no idea why.  Just another notch under the "must find alternative to mcafee" account...

Re: mmsshost.exe is using 77% of RAM

I would say this is a problem.  I ran full antivirus overnight and no issues.  I didn't buy my computer to have it only able to run antivirus software.

Re: mmsshost.exe is using 77% of RAM

Now, if my math is correct McAfee is taking 91.5 percent of my cpu.  At least with the IRS, they only take up to 35 percent.

Re: mmsshost.exe is using 77% of RAM

Now at 92.3 percent of my cpu available.  This is with no scans running or other things going on with McAfee.  Doesn't seem correct.

Re: mmsshost.exe is using 77% of RAM

I find it extremely strange, the two McAfee entries are continually updating and staying at 90+ percent as they change.  Something is definitely happening here.  How can I upload a log before my data plan prevents it?

Re: mmsshost.exe is using 77% of RAM

Logs are handled by support Selvan is the tech looking into this issue. I wish I could see this that way I could get the logs off to support the same day. Oh logs are gathered using specific programs Mcafee support have.

I hope the new year gives you more joy that the end of this 1.

  any comment re how this issue is progresing

Re: mmsshost.exe is using 77% of RAM

I removed and reinstalled McAfee LiveSafe and web browser security, rebooted and cpu usage was down to around 20 percent total.  I then reinstalled McAfee and the cpu usage is seldom above 50 percent and fluctuates lower for all processes running on my machine while a antivirus scan is in process.  Appears there is a problem with McAfee which causes it to hog resources.  I update mine almost daily manually.  Apparently the fix is to either remove/reinstall McAfee or switch to another product where the support is better?
