rootkit disk

I read some wheres on internet of a recovery disk that would scan through your local drives for rootkits. Does anyone know where this might be found.

The only two I know are
The Rootkit Hunter project
chkrootkit – locally checks for signs of a rootkit

But, you’ll notice that they’re both relatively old (at least rkhunter’s last release was 2012)

IMO better tools are pen testing suites like Backtrack (there are others as well).
