Possible Security Risk

Attention! Characteristics of the following security risk was identified in the system:

Security Risk	Description
Backdoor.SDBot.XD	Backdoor.SDBot.XD connects to an IRC server in order to join a network of other bots. It will then wait and listen for commands to be executed. These include further file downloads, network scans, launching an FTP server, and accessing the local registry among many others. Internet access will also be disrupted.
