Hi

I am using Kubuntu 12.04 X64. Under KDE user managament gui, when I click on my user account and then click on priviledges and group, I see a blank group under group section.

any suggestions would be highly appreciated.

When I run this command

cut -d: -f1 /etc/passwd


I get this output

root
daemon
bin
sys
sync
games
man
lp
mail
news
uucp
proxy
www-data
backup
list
irc
gnats
nobody
libuuid
syslog
messagebus
rtkit
avahi-autoipd
pulse
usbmux

colord
kernoops

hplip
kdm

libvirt-dnsmasq
sshd
festival
clamav
haldaemon
wineuser
maa
postfix
lxc-dnsmasq
havp
speech-dispatcher
mysql
nuauth
redis
ebox
zorp

Is it some indication of malware or indication of any daemon that has been removed ? How can I remove this blank line.

Thank you

Pawan
