Norton interfered with the installation of v 1.18.0 on a Windows PC with the message C:\Program Files\Cryptomator\patchWebDAV.ps1 | File | Infected. It proceeded to quarantine the file. Cryptomator is still working even without this file.
Welcome to the Cryptomator Community 
thank you for the report. It is a false positive.
The file is only necessary, if you are using the WebDAV volume type.
