Do you have a backup of your data?

The data I need is backed up off site, the MD5sums have been checked and the documents do not appear to have been altered. The rest of the data is all media and can be easily replaced.

I have just run RKHunter and it came back with the following -

The possible appears to be a false negative due to an early part of the test failing I can email over the complete log if needed.

I have just been exploring the /boot folder to check what else is in there apart from the object identified yesterday. There are multiple files in there all with apparently random file names -

root@nas:/# cd boot
root@nas:/boot# ls
dgilyydlff  hfoiqmgiuf  ikzyxanjay  mjntkohmfq  pvcfncudct  rylomtamis  tjqyhdntwa
exnkoixahd  ieugwzyxzn  inwwcpsfnt  ndagubygih  qphejjhrwp  sczlddtuwn  wlkwajhvrw
fzokpyuciw  igtdbjjjox  lyarglvtqd  pmctrpysah  qukhjkjmdj  sibhejtroq  xnsxvdaipy

Are any of these supposed to be present within the boot folder? I will carry on looking into the problem as best I can this end, I am unplugging the modem whilst performing checks to ensure no data is going outwards which is slowing the process but better safe than sorry.
