lkm trojan

[user list <debian-user@icantbelieveimdoingthis.com>]

I just ran chkrootkit on one of my machines at it turned up the
following:

Checking `lkm'... You have     4 process hidden for ps command
Warning: Possible LKM Trojan installed

How do I diagnose this further, and if there is an LKM trojan, how do I
remove it?
