    mchost application error




      I have a problem for some days. After I start Windows, the following error is occur (not all, but in most case):

      "mchost.exe - Application error

      The exception unknown software exception (0xc0000417) occurred in the application at location 0x1005f522."

      If I click Ok, then after about 5 sec the same error message appears.

      I have this only one of my computers, my notebook is good. I removed the Total Protection and reinstalled, but it has reappeared.

      Do you have any idea what can cause this?


      McAfee Total Protection (fully updated), Windows XP 32bit SP3 (updated),

      2 GB RAM + 2 GB virtual memory, x86 Family 15 Model 4 Stepping3 Intel(R) Pentium(R) 4 CPU 3.00GHz

      The latest McAfee Virtual Technician states that everithing is OK...

          Hi donkey,


          I have exact the same annoying message on my PC too. If I click it away it pops right up after a few seconds again. And it's in front of all other screens!

          I have this since a few days and I have nothing installed these days, only 2 updates from Micrososft itself . I would be very glad if somenone can help me get rid of this!


          (Also Windows XP SP3 / McAfee Antivirus Plus)

            Hello, I have the same problem, mchost.exe, has produced the unexpected exception of the program (0x0000417) ...... etc

            It all started when Mcafee Antivirus Plus upgrade to 2012. I give it to close or accept or cancel and out again.

            As this happens, I can not open the antivirus from any direct access or running as administrator.

            And when I get Acedo, stops dialing error.

            OS: win xp sp3, 1.6Gh Cpu, Ram 3GH.

            I need help with this annoying problem, and desistalado McAfee and reinstalled and get the same error.

            Thanks in advance.

                I too have the same issues.  Virtual Technician shows no issues.  just like doublev, i uninstalled then reinstalled and everything was fine up until the auto-updater ran and updated the program... not it is broke again.  frequently and annoyingly i get the mchost.exe errors popping up and if i try to manually update the total protection suite i get a different synchronization applicatoin error to pop up on that then it tells me it is all the way up to date....  This is quite annoying and if anyone has found a fix for this i would love it for you to share your thoughts/ideas on it.  Thanks!

                  Hiya same problem here, have attempted to debug but annoying message still there,


                  Mchost.exe - Application Error

                  The exception unknown software exception (0xc0000417) occurred in the application at location 0x1005f522.


                  If memory serves right, got a message to state a restart was required after the McAfee software updated, did not restart until it went on standby and then next day when i woke PC i did a restart, ever since that message appeared. Any help would be appreciated as nothing i can think of can fix it.

                      Just wanted to let everyone know I resolved the issue after spending a couple hours on the phone/chat wtih tech support.... they had no clue so I removed their piece of sh*t software and chose a different product.  I suggest you all do the same.
