So far, we have seen this specific behaviour with Symantec Endpoint Protection, though it is not limited to that product. Even with the client disabled, you will likely still see this issue.

This is a policy in Application and Device Control called "Prevent modification of system files (HIPS) [AC14]".
You will need to contact the administrator for Symantec Endpoint Protection at your organization to push out an exception policy for Shinydrive. You can also consult our Configuring Shinydrive Anti-Virus Exclusions article.
