    The problem started on that patch day and I do not think that persistently pointing to any malware is the way to go here, the culprit could be something else.
    As for the number of people having this issue: the numbers or users here reporting this problem is by no means representative, if noone repots here that can never mean that everything is nice and ok and noone has problems .
    Just curious - after you re-installed the OS on the one PC, did you apply the February MSRT update again, and if so, were there no more errors?

    The sole fact is that some guys have problems, actually one program is crashing under certain conditions recently, and that program is called MRT and that crashing apparently started with the last patch day, everything else is speculation and interpretation. (And I said "under certain conditions" because MRT works fine when started manually and it never found anything regardless of quickly scanning or fully scanning the system.)
    After the reinstall another issue still persisted since the last patch day: after installing any modern app the wifi connection is lost for a few seconds so that I have to install the apps one by one -- it was so after the patch day and before the reinstall of the OS and it was the same again after installing the last updates. I never had these problems before said patch day and maybe something got broken in Win 8.1 for some configurations.

    I reinstalled everything and that version of MRT is installed again but I got that error only during an automatic maintenance, so two PCs, both 32 bit, had that problem and the 64 bit never got that problem.

    Back to square one, full circle and all of that good stuff. If it is not malware crashing an extremely small fraction of machines, then what else could it possibly be?

    I can't think of anything else, myself. I happen to know a thing or two about Microsoft's OSes too, so it's not like I'm just saying, "Oh boy I'm stumped. Must be malware."

    I would not at all be surprised to learn that it is involving rikvm rootkit, which hides itself and cannot be seen without WinDBG. It is flourishing as of late.

    Interesting, my system is also 32-bit and I only got that error after automatic maintenance. Running the MRT tool downloaded from MS's website manually never shows any issues in the logs. Since 64-bit systems are now way more prevalent out there, that could be why this issue isn't being reported on a widespread basis.

    After I reinstalled the entire OS (as I got the problem that Windows Defender were unable to download any updates) everything was good so far except the other issue with the app updates; I do not think maleware is involved as I gave one fix-it from Microsoft a try and I think it did more bad than good.
    I never downloaded MRT manually, I used the same MRT which got installed via Windows Update (typed mrt into the Run window and used the different scan options), and everything worked perfectly and no error occured -- till an automatic maintenance started some time later.

    Yet another indicator of malware having been present.

    Hopefully it does not crop up again as I'm guessing you didn't use Killdisk.

    Well, it's Patch Tuesday, so I put the MRT.exe file back into the Windows/System32 and downloaded the new update for Malicious Software Removal Tool. Still show application error 1000 in the event log after I triggered a manual maintenance job. The file was not replaced by the update. It's still version 5.9.9902.0 with the same time stamp.
    I fact, in Windows Explorer, it shows the file was created back in 2010 and modified in February's update. So, I'm just going to remove the MRT.exe file again and just run the standalone version of the MSRT Tool for March.
    I'd be interested to hear if the other 32-bit users affected by this issue have the same MRT.exe file version?

    My system successfully updated the new version of MRT to 5.10.... And till now the errors have stopped. I have done like that: removed the mrt log in debug folder (windows/debug). Deleted the two files: MPGEAR and one more but cant remember what his name was in the Windows/Temp folder. Installed all the march patch updates and that's it. Hope this works also for you

    In the past I found that MSRT went into a folder where it wasn't easily accessible. Not only that, but it didn't delete past versions of it. MSRT is set to run a scan automatically if you d/l it along with the updates.

    For a while now I have been d/l ing the standalone version, running it before I do the updates, then refreshing the updates list. It disappears from the list once it has been run. Then I d/l the rest of the updates. I haven't had any problems with it doing it that way & I have easy access to it should I need to run it.

    I don't know exactly what happened, but somehow the new version 5.10 of MRT.exe is now in my System32 folder, even after I deleted the old version that was not overwritten when I updated yesterday. I'm not set for automatic windows updates, so I don't understand how it got there. Also, that file MPgear.dll is now gone altogether. Bottom line is now when I run maintenance (at least manually) there is no more event log error for MRT.exe. So, at least for now, seems like the new version did the trick.
