I have had the following error with the file you're referring to:
Administrative Event Viewer Error - Session "Microsoft Security Essentials OOBE" stopped due to the following error: 0xC000000D
The fix for that is to delete the file(MSSEOOBE.etl), and the file is rebuilt during the next reboot.
Another option you could try is going to MS and downloading the full definitions pack. This might correct any corruptions Install the latest Microsoft Security Essentials definition updates - Get the latest definitions - Microsoft Malware Protection Center
I also have this link for troubleshooting: MSE Solution Center Microsoft Security Essentials Solution Center
I did have something like that happen a long while back, I d/led the full definitions, it kept giving me the error similar to yours for about a day or two, and then the errors stopped.
Here is another link for you to look at: http://social.answers.microsoft.com/...e-24736b3cbf61
Another thought, make sure Windows Defender is disabled (MSE should disable it automatically). If it's not, you may have to disable it manually
