After deleting the above contents I rebooted Windows, and AVG9 started fine. I was also able to run Update, Scan, etc. I think it is safe to delete those files.
P.S. regarding the avg*.log.? and avg*.log.?? files in the Log folder: there are many files like
avg*.log.1
avg*.log.2
avg*.log.3
avg*.log.4
avg*.log.5
avg*.log.6
avg*.log.7
avg*.log.8
avg*.log.9
avg*.log.10
avg*.log.lock
It was my feeling that it is safe to delete the .1 ~ .10 files, but not the .lock files, which are all from the installation day, but 0 bytes in size. I don't know if they are actually needed or not, but I thought I'd leave them alone.
How does CCleaner currently remove AVG9 stuff - I cannot find anything in winapp.ini or winapp2.ini ?
Because the INI is embedded inside of CCleaner.exe which you can view (or modify)* using the freeware Resource Hacker.
When using Resource Hacker you'll find it located in CCleaner.exe at:
INI -> 273 -> AVG AntiVirus 9.0
*I don't recommend ever re-saving CCleaner.exe with Resource Hacker though since that will invalidate CCleaner's Digital Signature - meaning it's been modified and tampered with.

I have now also deleted all the *.log.lock files in the Log folder, and AVG9 is still fully functional. However, these *.log.lock files were immediately recreated, so I think we should leave them alone.
I would like to propose that these items be added to the cleanup of AVG9:
