Re: McSvHost.exe causes error on Shutdown


This just "happened" to me also on an XP desktop (aroung July 5th or so).  The desktop had been turned off for a couple of days.

I tried different things to fix it, but got the same results as you.  Sounds like we got hosed on one of the updates.

Had to un-install, run the mcpr.exe, and reinstall.

All is well again [ in v2010 heck ]

Man I miss the old version.  I sure hope the last 5 months have been worth it.

Thanks Mezzy.

Re: McSvHost.exe causes error on Shutdown

Well looking at those versions and your issues you really need to get the 10.5.194 version. It has some fixes and especially a uninstall reinstall via the MCPR removal tool (available in useful links tab) is probably thefirst thing to try. Sometimes an install gets corrupted.

I would also be interested in what the risk is that is it saying? Is it " update old". Maybe being triggered as no 10.5 version but I do not thinks this would happen only when it finds  old dats.

Re: McSvHost.exe causes error on Shutdown

Peacemaker, when you advised someone in your last post that "you really need to get the 10.5.194 version," what does that mean?  I thought we had absolutely no control over which version or update McAfee releases to its users.  I have the dreaded 2010 version of McAfee running, with the notorious ---and still unresolved--- McSvHost error, and my last update or "build" as you call it, is 10.0.580.  If the 10.5.194 "build" is better and so many people already seem to have it, how come so many of us still don't?

Peacemaker who is Peacemaker?

10.5.194 and the previous 10.5.178 are out but some servers are going slow giving them out. Really I thought every1 had 178 by now. When you have issues that are not acknowledged as known the 1st thought is to update to the latest version. The best way is an uninstall reinstall that is guaranteed to give you the latest as reinstalls are always the latest available.

178 has some fixes for updates and scheduled scan issues and 1 fix for this issue that seems not to help those who tried it.

My Pcs with the retail version Mcafee are on 178 but my son a kilometer away is on 194. 194 is being released throttled  ie say 1% of users get it at any time so that the servers are not overloaded. The PC with mcafee beta is on 178. 194 fixes are uninteresting so 178 is what you need at least.

Re: McSvHost.exe causes error on Shutdown

Just an FYI. I too was on Security Center Build 10.0.580 up until this morning. Have just now been upgraded to 10.5.194 (appeared to have skipped over 10.5.178) so rollout appears to still be ongoing; likewise , Virus Scan & Firewall were updated to versions 14.5 & 11.5 respectively, same time. Regards, GB.

Re: McSvHost.exe causes error on Shutdown


I was automatically upgraded to SecurityCenter v10.5.178 on 07/05/10 and to SecurityCenter v10.5.194 on 07/10/10.

On 07/13/10, I received a McSvHost.exe error on shutdown.

Shouldn't the upgrades have finally solved that issue?

Re: McSvHost.exe causes error on Shutdown

10.5.178 fixed 1 form of this error there are unfortunately several other ways this happens which are being fixed asap. Seems they fix 1 way and another turns up so they are lothe to update the fix as it could cause more angst

Re: McSvHost.exe causes error on Shutdown

I did as you suggested and uninstalled/reinstalled McAfee, and I now have the 10.5.194 version.  Since then I've shut down the computer twice and the first time got no error, but the second time the error came back.  Very, very annoying.  So I will have to go back to terminating the McSvHost prior to shutdown until McAfee completes the debugging process --which is taking forever and a day.

Re: McSvHost.exe causes error on Shutdown

I hate to be a cynic, but I seriously doubt this error message has multiple causes, since it started appearing with the 2010 upgrade and exhibits the same symptoms (i.e., only during shutdown) on all XP machines.

I think it's much more likely that they don't yet know what's causing the error. Windows reports that mcsvhost is trying to access an invalid memory address. That's the cause of the error message and it seems pretty straight forward. I can't believe they haven't yet found the problem.

The problem is somewhere in the program code, and possibly not in McSvHost.exe. It could well be caused caused by other code passing incorrect parameters to McSvHost.  There are a number of lengthy "McSvHostxxx.log" files (where xxx is a number such as 001). The files are in several subdirectories and some of them are filled with error reports. For instance, the log file in directory:

C:\Documents and Settings\All Users\Application Data\McAfee\MCLOGS\MISP\McSvHost\

contains the following errors for today, starting at 7:00 pm:

     McSvHost000.log -- approximately 500 error messages

     McSvHost001.log -- approximately 500 error messages

     McSvHost002.log -- approximately 170 error messages

There are several other log files recording large numbers of errors involving McSvHost. With all that documentation available, it would seem to me that the problem can be found in a reasonable time.

A log file in the MCLOGS\HomeNet\ directory specifically lists errors during shutdown, and goes back for months.
