My doman DDoS-ed for the first time.
2006.12.06
I developed sample rootkit "test.sys" which hides its file from all public rootkit detectors:
BlackLight Sophos ARK RootkitRevealer IceSword DarkSpy SVV ... GMER Rootkit doesn't create hooks ( SSDT, IRP, SYSENTER, IDT, inline, FSF ) and its modifications are not visible.
You can see it in action in these movies: test.wmv, test2.wmv ( 0.9MB, 0.7MB Windows Media Video 9 codec ).
The detection of this type of rootkit will be added into the next version.

Answer:On the "Rootkit Tab" select only: Files + ADS + Show all options and then click the Scan button.
Question:Can I launch GMER in Safe Mode ?
Answer:Yes, you can launch GMER in Safe Mode, however rootkits which doesn't work in Safe Mode won't be detected.
Question:I am confused as to use delete or disable the hidden "service".
Answer:Sometimes "delete the service" option wont work because the rootkit protects its service. So, in such case use: 1) "disable the service", 2) reboot your machine, and 3) "delete the service".
用过一段时间，后来删了，没太用！
