Hello,
I think that we are making progress, and I am not just saying that! Previously, the logs were an unearthly mess of seemingly unrelated errors.
Have a look at this log snippet:

That looks to me like there is one more corrupt file/registry key. Just one, causing the rest to fail. Especially with that error code.
Now, the Update History confusion is to be expected after resetting in Aggressive Mode. To clean out everything, the history is deleted (because the history is much more than just a log file) All previous updates are still installed and protecting you, they just don't show in your History.
The System Update Readiness Tool can only correct some errors. Unfortunately, this is beyond the scope of that tool, and so you are now reling on me!
Q1: The corrupt files from your CheckSur.log are quite common, and are usually caused by some Windows Update confusion/mess up. Your continued problems are less common, and may be caused by a dodgy hard disk. I shall see if I can figure out whether this is likely from the log files, and then you can test it if necessary.
Q2: It could be, although it would be more common for an A/V to prevent Windows Update from updating files than actually corrupting system files.
As you rightly mentioned in your first post, some of your corrupt files originate from KB2443685, and interestingly, I have had more cases with files from that update becoming corrupt than any single other update.
My slight worry is that this may actually be a registry error. These are not impossible to fix, but they are harder to fix, and there are far fewer available scans (DON'T try a registry cleaner, they will not help, and often makes things worse - I am talking about purpose build Windows Update tools, eg ones I have written) and I can't fix it until I know exactly what is corrupt, whereas with files I can replace a file if I am suspicious.
Please run an sfc /scannow, by opening an Elevated Command Prompt:
http://www.sevenforums.com/tutorials/783-elevated-command-prompt.html, typing
sfc /scannow, pressing enter, and waiting about 15 minutes
Then please attempt to install this standalone update:
http://www.microsoft.com/technet/security/bulletin/MS11-038.mspx
Only after doing both of those, please copy to Desktop, zip, and upload C:\Windows\Logs\CBS\CBS.log.
Thanks a lot!
