Malware Scanning Verdict Values
A malware scanning verdict is a value assigned to a URL request or server response that determines the 
probability that it contains malware. The Webroot, McAfee, and Sophos scanning engines return the 
malware scanning verdict to the DVS engine so the DVS engine can determine whether to monitor or 
block the scanned object. Each malware scanning verdict corresponds to a malware category listed on 
the Access Policies > Reputation and Anti-Malware Settings page when you edit the anti-malware 
settings for a particular Access Policy.
The following list presents the different Malware Scanning Verdict Values and each corresponding 
malware category:
