Anti Rootkit Resource

http://www.ntinternals.org/anti_rootkits.php

Maybe it will be useful to someone. It includes rootkit detection and hidden things detection software. I can't vouch for its up-to-dateness but it's a nice list.

EDIT: Just a note; Never use an old version of a rootkit detection utility unless the only changes are minor and don't apply to the actual detection functionality.

:) good list

personally, I use Sophos or GMER regularly.
