Re: Hacked or not ?

I have seen this as well, it is most likely a false positive.
Additionally, slower or more heavily loaded machines seem more likely to
generate false positive for LKM.

As a side note, there really ought to be a way for admins to double check
the output from chkrootkit Google helps little. Any offers..?
