If you are having issue of Firewall keeps off and cannot be turned on, please try following steps:
If Firewall shows "ON" in step 7, the issue has been fixed. If it stays "OFF", please continue following steps:
If Firewall stays off even after these steps, please perform an uninstall and re-install. It is also recommended to run McAfee Cleanup Tool before re-install to make sure a clean install will be performed.
We for the inconvience caused by the issue. We are currently investigating it and will put migration methods into next release as well as McAfee Virtual Technician.on 3/21/13 6:21:51 PM EDT
Thanks for posting your suggestion, it’s good to try these steps
you can use the command line
for %1 in ("%programfiles%\mcafee\mpf\*.dll") do regsvr32 /s "%1"
for %1 in ("%programfiles(x86)%\mcafee\mpf\*.dll") do regsvr32 /s "%1"
if you're using a 64bit OS (I think!)
instead of typing each of those lines separately - its a lot easier
The suggestions here didn't fix the problem for me. I found the following on Microsoft.com which took care of the issue immediately:
This may be caused because the “NT Service\MpsSvc” account does not have adequate permissions on the following registry key
Windows 7 (all versions) / Windows Vista (all versions)
I'm having the same issue for couple of days now. didn't do anything before this firewall thing happen. I followed the suggested steps here but still the firewall is turning itself off. I tried starting the service MPSSVC using the administrative services but i'm getting "error 1068: The dependency or group failed to start."
What's going on again McAfee???
That said https://community.mcafee.com/message/174222#174222
says a reinstall fixed it
did you mean "StartOrder" on the "Start" ???
is it compatible with Windows 8 pre-installed ??
by the way I'm using Dell Inspiron 3521 Windows 8 Pre-installed 64bit
I have used this above fix twice from lixiao whose orignal comments above started this thread. His / her solution works. It fixed my random toggling of my McAfee firewall from going from on to off.
In my case, just following the steps 1 to 7 of the first post on https://community.mcafee.com/message/280363, seemed to sort it out, but I have just had to apply the fix a second time to the same PC after a couple of months without my other half reporting a problem, but it may have gone un-noticed for a while...
I urge you to check whether McAfee is faithfully reporting the status of the Firewall.
I recommend using a better check (e.g using the Start - Run - services.msc to confirm the McAfee Personal Firewall Service has been started again) rather than simply looking at the McAfee window, because on my PC, prior to fixing the problem, McAfee was reporting that the Firewall was On, but the services.msc disagreed with it, reporting it was Disabled. Within McAfee, I found I could reach the point where I had the button permitting me to turn it Off (with all McAfee indications up to that point saying it was On), but the services.msc saying it was Disabled. Only after some time reporting "On" (perhaps about 15 to 20 minutes after switching on the PC) does McAfee decide that in fact it is Off. At that point, the red warning banner appears, and the "On" button is availabe but ineffective.
In my case the simple remedy seems to have been effective, since I applied it on 7th June, but it recently failed again in the same manner, and I have employed the same fix again. As before, this has been done without the "fixit" but has only been applied this evening, and only for the single reboot required by the process.
Win XP SP3, and no Base Filtering Engine required.
