    Started happening just after the February updates, so it may go away when the March updates come out.
    lol 2 files scanned?

    That's not very prudent. I think it's malware.

    Recommend Killdisk then install Windows, regardless if it is or not.

    I did a complete scan, but I scanned those 2 files independently as well, just in case the respective A/V programs did not include them. Luckily, I saved system image backups of my C: drive from before the Windows updates, so if it causes any problems (other than the event log errors), I can always restore. Thanks, but I think I'll take a more conservative approach for now.

    Just wanted to let you know that I, too, suffer from the same problem.
    My computer is 100% clean and no malware is present.

    I consider myself an advanced user and can assure you there's probably nothing wrong with your computer.
    I started receiving the same errors just after applying last February security updates.
    I hope this issue will be resolved by the time Microsoft will release security updates for March (including the Malicious Software Removal tool).

    It sure does generate lots of errors, though.

    Assure, probably? Quite the contrast.

    Why do you suppose it's crashing then?

    My guess without having access to the machine and going by just a hunch is some kind of rootkit.

    Do the math.
    You have two people who report the same issue. Plus another (myself) using a machine that can't access the Internet...

    There are probably more, but not everyone bothers to check the Reliability history.

    For the record another failure today- MRT.exe stopped working. I don't know if it`s related but windows defender definitions won`t install- neither through Windows update nor through Windows defender itself. This is the error:

    Hmm.. This one's different. I have no issues installing definition updates.

    In order to fix the MRT errors I followed this tutorial DISM - Fixing Component Store Corruption in Windows 8. I have used these commands before but no problems with Windows update. But since two days I couldn`t update Windows Defender.
