This Trojan is designed to launch massive attacks on servers by sending an overload of requests.
Securemac is already offering a free tool to remove the Trojan and can be downloaded at the following address: iWorkServicesTrojanRemovalTool.dmg.
You can also perform the same function by following this procedure:
1) Open the terminal
2) sudo su admin password
3) killall -9 iWorkServices
4) rm -r /System/Library/StartupItems/iWorkServices
5) rm /private/tmp/.iWorkServices
6) rm /usr/bin/iWorkServices
7) rm -r /Library/Receipts/iWorkServices.pkg
That's it, but remember it is easier and much safer to simply purchase iWork 09 from the Apple Store
