Backdoor.Sadmind

Backdoor.Sadmind is a backdoor worm program that may affect systems that are running unpatched versions of Microsoft IIS or unpatched versions of Solaris.

It means that you have visited a Website whose server has been compromised by Backdoor.Sadmind, which replicates only on Solaris systems.
