There are lots of simple commands you can use depending on how good the
was.  Using find to locate directories that should not exist and files
have been changed recently.  Comparing output of ps against /proc (only
in linux), etc.  
These are very rudimentary and will not find some rootkits, but they
still work well 
in the general case.  As far as pre-built tools, I have not used any.  I
just keep 
writing more scripts ;)
