# It will scan in compressed archives, in mail archives, in NTFS alternate data streams and use cloud requests

# You can remove the "/quick" argument to do a full scan but that may take longer than what FRST can handle.
# You can use argument "/quarantine="[folder]"" to put found malware into quarantine, but I personally prefer first verifying the detections.
