Since I just got done doing 4 hours of firewall changes for my company, so I will relay a bit of information,
The payload looks to be a Denial of services attach against
www.sco.com, so if you internet access becomes very very slow you might want to virus scan your systems.
It also installs a back door trojan that uses port 3127, so if you have a firewall that can block in and out bound traffic I suggest you block TCP 3127
