That was just an example above for future reference.

When does the journaling start?
Ex: I install a PUA app. Its gets auto set to Monitor. Does journaling start after the installation or before?
If it is before, then the above test I did didn't work because the rollback procedure did not delete the installation files of Foucs Writer, only the changes the program did after installation.
Only the changes made by the monitored process will be journalled, so only those changes would be rolled back.
Using what you saw with Focus Writer as an example, journalling and rollback worked as would be expected. The Monitored file was the Focus Writer application file, which created the document, so the change of the created document was rolled back. Since that process did not create the installation files, those files would not be deleted.
If you wanted to remove the installation files, you would need to go to Manual Threat Removal, and select the installation file for Focus Writer. If the installer was monitored and journalled, the changes made by the installer would rolled back.
