After the most recent Avast update I have noticed a new unexplained symbol in the scan results tab: A ghost with a red exclamation point over it. This symbol shows on all of my full system scans. All of the scans show no viruses or malware detected, and nothing is there to explain the purpose or meaning of this icon. Could someone please tell me what this symbol means and why it is there?
