    Hi.
    Windows XP Machine.
    Using latest Smart Security 4.X
    It has two Vlans.
    On one Vlan it is reporting this...
    LEVEL : Critical Warning
    EVENT: Detected unexpected data in protocol
    Source: It shows 5 ip addresses in the same Vlan (each IP on it's own line)
    Target: it shows the same X.X.255.255 where X is the Vlan.
    Protocol: UDP

    I have added these IP's to the trusted Zones and it still reports the Critical Warning.

    Is there anything else I can try.
    I understand that the problem could be something on that network broadcasting somethign via udp.. how do I get it to NOT report the Critical error?

    Hello,

    To determine what part of the payload is generating this error, an examination of a packet capture is probably required. Please contact ESET Customer Care for assistance.

    You can capture the flagged packets by following the instructions in ESET knowledgebase article:
