W32/Sdbot-AFU runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.
W32/Sdbot-AFU spreads via network shares and by exploiting the ASN.1 (MS04-007) software vulnerability.
When first run W32/Sdbot-AFU copies itself to:
