FJJP,
BKDR_SDBOT.M is backdoor program allows a remote user to access and control the infected system via Internet Relay Chat (IRC).
Through the IRC channel, the malicious user can send commands to the backdoor to process on the infected system, leaving the system compromised.
The good news about that program is that it is NOT Destructive, so your computer programs and operating system should be intact. The bad news is that it is a backdoor program that allows the user not only to control your computer, but to also access any and all of your data.
Take Care,
Richard
