When Symantec AV engine updates, it changes the directory. As the error indicates, there was an issue with the directory generation.
Restart ICAP service.
Restarting the ICAP service will reset the directory pointer to the proper directory, and the system will properly update.
This is a known issue and will be addressed with the updates in Content Analysis version 2.3.5.1.
