Service account used for Kaspersky Administration Kit and it functional make possible attack on other hosts

This function makes ICMP scan and also tries to use SMB protocol by using service account which can be
used to run SMBrelay attack and gain full control on secured network. By default "Scan IP subnets"
scans subnet every 7 hours. Attacker just needs to run SMBRelay tool and wait. Attack is possible
because Kaspersky service account have Administrative rights on hosts in corporate network.
It's mean that attacker can attack any server or workstation where this service account has rights.
