You can store quarantined files in the USB device, instead of on the target computer but you cannot use the Scanning Tool to store other files.
Scan: This function is enabled for files that are tagged "ignored" or "unable to fix."
Selecting Scan opens a confirmation message box for users to choose the appropriate scan action to apply for the selected file(s).
Restore: Select a file or files and click this button to put the file back and leave it in its original location. Refer to Restoring Quarantined Files.
Restore files only if you are sure that the file is not infected.
