No. I would not complete that operation that you just found via Google.
It will initiate a sequence of events that will "add" more Symantec files to your system and possibly make matters worse.
Your problem-solving "logic" is fine, but would end up with the wrong solution.
(I'm generally encouraged when folks start trying to "think things through". It's the beginning of learning!)
----------
Since you've run the Norton Uninstall Tool, and still have conflicting file items of Symantec on your machine we need to do a little more work.
First:
In Add/Remove there should be no items with labels including Symantec/Norton remaining in the list of installed applications.
Second:
LiveUpdate! "may" still be in the Add/Remove List. <--- uninstall it if it is there.
Third, after verifying that no further items with labels including Symantec/Norton are remaining in your Add/Remove list...
--- Use Windows Explorer to Navigate to C:\Program Files\
and
--- Use Windows Explorer to Navigate to C:\Program Files\Common
Browse through your Program Files in the two addresses above.
You will probably find a folder at C:\Program Files\Symantec
____________
The Symantec Folder contains the S32evnt1.dll file that is causing problems.
Ordinarily, I would DELETE the entire Symantec Folder and all of its contents.
However, I recommend that we "proceed cautiously".
___________
Fourth:
Please Create a New Folder, similar to the following:
C:\New Folder
rename it as:
C:\TempMovedSymantec\
Fifth:
Navigate back to C:\Program Files\Symantec\
Use - Edit - Cut (to remove the Symantec Folder and all of its contents from C:\Program Files\)
Sixth:
Navigate to your New Folder at C:\TempMovedSymantec\
Use - Edit - Paste (to copy the Symantec Folder and all of its contents into C:\TempMovedSymantec\)
It will now appear as: C:\TempMovedSymantec\Symantec\
And will include at least one file (S32evnt.dll) amongst others that also got moved, but which we are not concerned with right now.
__________
Seventh:
"If" there are Symantec folders in C:\Program Files\Common\
"Then" please Create another New Folder and rename it as: C:\TempMovedCommonSymantec\
Cut\Paste any entire folders that are labled as either Norton or Symantec, which you may find in C:\program Files\Common, into this New Folder.
__________
We may need to do some Registry work in addition to the above.
I am hoping that just moving the Symantec Folder will cause it to drop off the radar and cease interferring with the PitTest and the general functionality of your machine.
After running your machine for a few days with the Symantec Folder(s) moved, if there are no errors or conflicts, and the machine is running fine with the Symantec Folder no Moved to the new TempMovedSymantec location, we can consider Deleting it entirely.
___________
We are "just moving it" for now, in case some odd reason pops up that makes us want to put it back.
I don't think we will.
____________
Next:
Go Run another Pit Test.
Hopefully the Pit Test will now Run without the Error message.
Let us know.
__________
You "should" also find that the file: (C:\WINDOWS\system32\ntvdm.exe) will no longer be appearing in your Pit Test.
It is the 16-bit environment program to allow for the 16-bit portion of Symantec.
It should also be gone, but we'll wait and see from your Next Pit Test TechExpress.
_________
You commented: "I guess this is as good as it gets.. "
Actually, it is looking pretty darn good.
I realize that you'd like to have a properly functioning internal CD-Unit.
You may want to take additional action later to physically replace it.
But for now, you are getting your machine to a condition where it is running well.
Let us know if there are other considerations about your machine's functionality that need attention.
Best Regards
