Alaina sets her antimalware solution to move infected files to a safe storage location without removing them from the system. What type of setting has she enabled?

A quarantine process or setting will preserve malicious or dangerous files and programs without allowing them to run. This allows defenders to retrieve them for further analysis as well as to return them to use if they are determined not to be malicious, or if the malicious components can be removed from needed files. Purging, deep-freezing, and retention are not terms used to describe this behavior or setting.
