It constantly monitors the file system, and if it sees a sudden burst of encryption, will freeze the concerning process. Yes, you&amp;#x27;ll &amp;#x27;lose&amp;#x27; at least a few files, but major loss is prevented. Obviously, you&amp;#x27;ll need to turn it temporarily off if you want to do any legit encryption.
