Re: McSvHost.exe causes error on Shutdown


Errors do indeed cause damage! Most hard drive fragmentation is caused by an error. And, many errors do not generate alerts.

This error is related to a "memory write" function. Specifically, the McAfee software can not complete it's memory write at shut down; so, when the computer is restarted McAfee isn't aware of the changes which generated that memory write.

The error is usually generated [on my network] at shut down on those days when either a complete scan or a manual update has been run.

Further, in the time this error has gone uncorrected, I've noticed addtionally "nuisances" ocurring with McAfee's operation: failure to load updates when updates are available {website has updates listed but my software will declare "no update available" or "your services are up to date"}; failure to load applications {most notable the "Real Time Scanning"} at start-up; failure to scan all files and folders on system [even though the scan settings are appropriately saved] during a full scan; failure to run scan of DOS and registry during boot; failure to block malware and suspicious files; and, failure to maintain quarantine of infected files.

I have no doubt all of these problems are associated with the malicious code which caused the loss of so many systems several months ago. I have no doubt McAfee failed to thoroughly examine their software for additional effects of the code before they issued an update to remove the malevolent script.

Re: McSvHost.exe causes error on Shutdown

I am still surprised why this error (McSvHoost error on shutdown on Windows XP) has not been corrected for so long a time. It is a program written by MacAfee

programmers themselves and they are specialists aware of any subtleties in windows. So, I do not understand why they need so long  a time to do find out a solution?

Re: McSvHost.exe causes error on Shutdown

I also wondering as this issue is no 1 reported issue atm so they are giving it heaps of priority.  I do expect something soonish.

Re: McSvHost.exe causes error on Shutdown

Hi Wetmoref2,

   Just to pass on some information, this issue is in no way related to the 5958 DAT issue which happened at the end of April. McSvcHost and Svchost are totally unrelated files, made by 2 different companies.

   In all my discussions with our dev and senior techs, the cause of the issue is that this service doesn't shut down in the time Windows allocates for it. There are actually more than one cause of this, which is why various updates have resolved the issue for some, but not everyone, and why a 100% cure-all hasn't been released yet. Some people have been resolved though, so some progress has been made. We've still got work to do though, and it is being worked on at high priority.

When we say no data is lost, what we mean is that it isn't a critical stop or a blue screen. It doesn't happen in the middle of an application, causing you to lose work. Hard drive fragmentation would have to be extreme to cause data loss, mostly you're just going to see some performance slow down. Regardless, I have not had any reports of that from customers.

The list of items you gave sound like they need to be looked into. Have you contacted support for any of them yet? If so, did they give you an SR number? I'd like to have a tech look over them, see if we can't get to the root of the issue and get you sorted. Regarding the updates being available but not downloading, I wouldn't know for sure without looking at what update you were trying to download, but we don't make updates available to the whole customer base at one time. We roll patches and updates (and new versions) out in groups for bandwidth purposes. We've got something around 40 million people downloading, so it has to go in chunks.

Please do let me know if you have an SR number and I'll take a look.

Re: McSvHost.exe causes error on Shutdown

I went 12 days using Version 10.5 without seeing the error and last night at shut down the McSvHost.exe reappeared.  It was reported by a McAfee tech that the issue has been fixed on some computers with the version 10.5 update.  Not true, it has just slowed down and doesn't happen as often as it used to.  Before the Version 10.5 update I used to see it almost every time I shut my computer down.  I guess if I only see it every 12 days or so I can live with that for now but sure would like to see this issue get fixed.  It has been around way to long and I am getting tired of hearing they are working on it and its on there top priority list.

Re: McSvHost.exe causes error on Shutdown

Thank you for your response wetmoref2 but please do not mis-quote me.

You refer to errorS generally and of course errorS can cause damage to a computer including the hard disc. However I am not talking abut errorS generally as you are leading others to believe but a specific problem at closedown which the feedbacks I've seen suggest causes a problem of a message displaying prior to closing.  I agree one would expect a solution to have been found long before now but the fact is it wasn't and nothing any user says is going to alter that.  Clearly you are having a great deal of problems with your systems and I appreciate it can be extremely frustrating and I am sorry to hear of your problems.  The complaints I've seen in my email relate to a message coming up at closedown only - nothing about damage.

Re: McSvHost.exe causes error on Shutdown

Re DAT update are you looking at the enterprise pages to see what DAT is current. These do show up slightly earlier than the dat arrives and as Somer says they are grouped not just opened worldwide to download.

I did say back 2 mths when I was testing the beta 10.5 that this issue was marked as fixed in the fix list they gave me. Some users here tried the beta and reported nothing fixed so I did not push the point. What is strange is since my test box updated to 10.5 zero messages but then I am only having 3 in 45 shutdowns now with the issue so really cannot say it helped.

It does help update scheduling and scanning though.

Re: McSvHost.exe causes error on Shutdown

I'm confused by the 10.5 version number. What version number are you refering to? The Security Center?

I have Security Center 10.0, Virusscan 14.0, and Firewall 11.0, according to the about page.

Re: McSvHost.exe causes error on Shutdown

The RAM minimum thing is a bunch of bunk (pardon the expression). Obviously, HP has very knowledgeable technical support people --- NOT. I have 2 GB and I've had the error problem for months.

PC World surveys of users indicate that HP support is pathetic at best -- near the bottom of the list.

Re: McSvHost.exe causes error on Shutdown

Every product has a .5 in the version except Site Adviser ie security center 10.5 latest.

Agreed re ram as I said My son in Law's PC has it with 2gb and has it bad. Nearly every shutdown but he only saw it when I asked as he turned off the monitor immediately after clicking shutdown.
