Did you delete the MSE Programs file again?

The folder and EppOobe.etl file re-appear after a reboot...

I just did two new reboots, after checking to make sure that the EppOobe.etl file was not in the Microsoft Security Essentials/Support folder. The original error did not re-appear, nor has that file reappeared. I have not removed the folder Microsoft Security Essentials or any of the other files inside of the Support folder under this folder.
Should I remove the entire folder by a simple delete, I know of no other way to remove it.
Also, I just paid more attention to the two folders next to the MSE folder, Microsoft Antimalware - which has multiple, almost empty - but not quite, folders underneath, and Microsoft Security Client, which has a Support folder and an identically name EppOobe.etl file in it. No clue as to how similar this is to the one in the MSE folder.
The operative question is should both of these folders and their contents also be removed in order to have a completely clean uninstall? They are not available through the Program Manager Programs Uninstall feature.
MFR, do you also have these folders? Is it safe to just delete them?
Thanks!

You uninstalled MSE, correct? Then why are you asking if it's OK to delete the MSE programs folder after I just told you to delete it?

Yes, I uninstalled MSE. Since the initial reference was to an MSE program file, not a folder, I wanted to double check to be 100% certain is was ok to remove the entire folder.
I have deleted it, thank you, and done a reboot.
The Events Viewer had zero entries, and the MSE folder did not reappear.
I will track this to ensure that this fix continues to work.
I assume the Antimalware and Security Client folders should be ignored for now?
I must be off, will sign back in tomorrow afternoon with any new status updates.
Thanks again for all the help, hope this is the fix!

You owe it to yourself as someone who is tech oriented to do what most tech enthusiasts do and Clean Reinstall - Factory OEM Windows 7 to shed the bloatware and enjoy Win7 in its native perfect state.

There is just no comparison how much better it is, plus you learn so much!

It has been a while since I posted, but I do finally have a resolution to the problem.
I was able to completely removed MSE, by first removing it through the Programs and Features interface, then by going into Explorer and removing the folders that remained, and finally cleaning out all the remaining entries in the Registry following the instructions listed here How to manually uninstall Microsoft Security Essentials 2.0.1963 if you cannot uninstall it by using the Add or Remove Programs item.
However, a few days later I started getting entirely different errors and issues when I booted up.
At this point I had a hardware specialist run diagnostics and he determined that the motherboard was going bad, and in a three year old machine, to replace it would require replacing the processor so we were getting into some real cost issues.
For me it is more economical to have a new custom (and much faster) machine built by a talented local technician. The new machine (parts just ordered from NewEgg) will have the Intel Core i7-3770K Ivy Bridge processor, 16GB of RAM, 2-1TB hard drives, the ASRock B75M-DGS LGA 1155 Intel B75 SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard, a Sapphire Radeon HD 7770 Video Card, and yes, a squeaky clean, no bloatware copy of Windows 7 Home Premium.
Thank you again for your help, and I hope this post can help others.
