Re: McSvHost.exe causes error on Shutdown

Can i please ask to which particular update are you all referring to that has disabled your computers, this is frightening, well to me it is I am not that computer literate.

i have been posting on this thread as i do have the problems with the shutdown and the scan not working at the time it should.

But this update you are referring, i am not at all sure if I have received this update, and if I have, how can I tell this. When did  the update occur please.


Re: McSvHost.exe causes error on Shutdown

It was dat update 5958. The current 5959 is fine. What the issue was that the 58 dat falsely detected svchost.exe as a virus and deleted it. Of course this stopped XP booting etc. The issue seemed to be XP only.

This was at 6am ish US time. So update safe now.

Plenty news items re it around.

Re: McSvHost.exe causes error on Shutdown

Total Protection indeed!! Last night I tried to run a scan, due to all the problems, and immediately after starting, the program shut itself down, said there was a virus and re-booted. I have not been able to get back in ever since (I'm at work now). I had to bring my PC to a technician and that will cost me probably twice what this useless program costs. I have been a MacAfee user for 3 years, but no more. I am awaiting a phone call from the techie to tell me how much damage was caused by MacAfee program and hope my programs/data can be salvaged. One more thing, next year when it is time to re-new and I refuse, i will need to keep an eye on the auto renewal settings. Even though mine was set to "no" a year ago, for some reason it was automatically changed to "yes" just before renewal date...pretty sneaky trick if you ask me. Horrible program and even worse technical help.

Re: McSvHost.exe causes error on Shutdown

I had 2 machines go down at around 7pm UK time and jumped up and down for hours wondering what the heck had happened... at around 4am UK time I found the McAfee Threat Center post (dated 21 April - not the current one) which I couldn't follow as the folders mentioned didn't exist on my system... possibly the enterprise edition fix?  Anyway, after being pointed to this thread via Ehapi's post I followed the steps given by Somer Pyron and both machines now work..... phew! No sleep but at least I can work today!!!

Re: McSvHost.exe causes error on Shutdown

My (non-corporate) desktop running XP Media Centre Edition SP3 did the same with this false positive I think (noted a supposedly detected Artemis! trojan at about 7.15pm) and did the whole constant restart everytime I tried a scan. Since then however it has gotten stranger, in that like one or two people it appears to have destroyed that machines internet connection, and somewhat altered the theme being used in XP.

Using the SuperDat .exe in the provided (but admittedly corporate) fix has restored svchost.exe and given some fuctionality back to McAfee Security Centre, but with the internet connection still missing, I can't replace the dat via uninstalling or updating, and the only \Engine folder I have under McAfee is in Program Files\McAfee\VirusScan\Engine which has two sub-folders. I noted the 5958 dat is in the DAT folder that sits at the same level as the Engine folder in the VirusScan directory. Not clear then whether I ought to be trying to add in the fixed DAT file and then look at the internet connection, or remove McAfee, fix the internet connection and then download an updated version.

Apologies if this isn't the right place to be posting this, but I've no idea where is exactly.


Hmmm, ok, internet connection came back up and an update has been installed saving me the trouble (but I'm still going to remove and replace with a newer version I ordered a while back mistakenly). Allthat fuss over one little file...

Re: McSvHost.exe causes error on Shutdown

Yes, the Enterprise fixes don't work for mere mortals using the home versions unfortunately.   We've suggested that the two be more aligned so that could occur.

Try this.  Go to C:\Program Files\McAfee\VirusScan\DAT and delete the contents of that folder.   You may have to do it in Safe Mode, it's been a while since I tried it.

Reboot and right-click the McAfee icon and update it.   Actually it should go straight into update mode anyway.

DAT 5959 cures the previous bad DAT.

Re: McSvHost.exe causes error on Shutdown

Whoops, thought I shouldn't tried it. Oh well, the enterprise fix did sort of work, but now I have 9 svchost processes running simultaneously, 3 each of Local Service, Network Service and System. Doesn't sound right to me, but I've no idea what to do about it.

Re: McSvHost.exe causes error on Shutdown

I have 15 running on mine (Vista Ultimate x64) so I wouldn't be concerned.

Re: McSvHost.exe causes error on Shutdown

McSVHost error went away...all was fine...then it came back...sigh.  Back to same problems as before.

Through all of this though, I would like to congratulate Peacekeeper for trying very hard to "keep the peace" certainly live up to your name!

Special kudos to Peacekeeper!

McAfee...please fix this once and for all.

Re: McSvHost.exe causes error on Shutdown

Hi Everyone.

This DAT file that crashed peoples pc's out, what time did this update take place in UK time?

As i was on my main computer all yesterday (21st april) till about 10pm UK time I DID HAVE MCAFEE UPDATES IN THE EVENING (cant remember if it was a normal update or a software update)


Switched off at 10pm uk time, turned on 22nd april at 12pm UK time and an error occured on my computer it said as follows (or similar):


DCOM server process launcher service terminated unexpectedly and windows needs to shut down***.

My pc keeps switching off, restarting all the time.


My pc was working fine till i switched it off at 10pm.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ UPDATE FROM ME ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

As regards this issue I had above, I checked out the 2 links someone told me to look at, and I DID have that update where I had 5958 DAT file which caused this start-up restarting error. (not the McSvhost.exe error). I have taken the steps Mcafee listed in the topic to which this worked 100% why cant they find a cure to the McSvhost.exe error
