you really almost *never* can be 100% sure. The latest root kit are running
in the kernel, dont need to change any command as they hide information
at the system call level. Some are really difficult to see, they dump
the binary on the disk only when they need them then erase them etc..
etc..etc.. honestly, i think the rootkit technology is far in front of
the forensic and worst detection tools commonly available so, my recommendation,
maximum paranoia ..
