Question
Why are files re-quarantined after being released?
Answer
Released files are registered as safe files based on the hash information of the file.
If any changes are made to the file, the hash information of the target file will change. Therefore, HENNGE Cloud Protection treats it as a different file and may re-quarantine it.
By setting the target file as exempt from scanning in each policy, you can avoid re-quarantine.
