Hello! Sorry for the english I'm using google translate.
Yesterday I installed DSM 5 beta on DS713 +, this turned into another, much better!
But appeared a problem, searching the internet I found that it was a virus, this must have been on DS for long.
After the update it started to present an error message every command, to remove the problem I did the following:
Login as root, put a # before the export LD_PRELOAD ....
DiskStation> cd / volume1/homes/admin /
DiskStation> vi. Profile
# export LD_PRELOAD = / lolz/jynx2.so
export PATH=/opt/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/syno/sbin:/usr/syno/bin:/usr/local/sbin:/usr/local/bin
