Actually your PS3 is perfectly fine. . .

HOWEVER, I have scanned your bank account, and you are about to bounce a check. If you want to prevent the check from bouncing, you should immediately add me as a joint account holder so that I can make sure the funds stay available.

Yeah, that sounded ridiculous too.

It's a scam to scare people into buying their product. You have several things going for you...

1) you're using Linux, not likely to get a virus.
2) you're using YDL which is a PPC based distro, even less likely to have viruses for due to very small install base.
3) if they had a scanner that would work through the web, it probably wouldn't work in Linux.
4) you have a PS3 (this doesn't affect your ability to get a virus, but it's still an awesome game system)

Have fun and welcome to LQ!

Forrest

This was of course no scan at all - just a standard "result" returned to everyone to pretend ... whatever.
It did not even bother to actually check for your OS - had it done that it would not have offered you (to BY of course) some windows-only program to "protect" you from what they say you are vulnerable to...
A simple firewall - and only running services you really need - can indeed further your security - which is already very high, as has been explained.
As an example - the firewall-script I use on my laptop:
Code:
#!/bin/sh

# Begin

startFirewall() {

# Insert connection-tracking modules (not needed if built into the kernel).
modprobe ip_tables
modprobe iptable_filter
modprobe ip_conntrack
modprobe ip_conntrack_ftp
modprobe ipt_state
modprobe ipt_LOG

# set a sane policy:    everything not accepted > /dev/null
iptables -P INPUT    DROP
iptables -P FORWARD  DROP
iptables -P OUTPUT   DROP


# allow local-only connections
iptables -A INPUT  -i lo -j ACCEPT
# free output on any interface to any ip for any service (equal to -P ACCEPT)
iptables -A OUTPUT -j ACCEPT

# permit answers on already established connections
# and permit new connections related to established ones (eg active-ftp)
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

#ssh
iptables -A INPUT -p tcp -m state --state NEW --dport 22 -j ACCEPT

# be verbose on dynamic ip-addresses     (not needed in case of static IP)
echo 2 > /proc/sys/net/ipv4/ip_dynaddr

# disable ExplicitCongestionNotification - too many routers are still ignorant
echo 0 > /proc/sys/net/ipv4/tcp_ecn

# End

}

# Begin firewall.stop

stopFirewall() {

# deactivate IP-Forwarding 
echo 0 > /proc/sys/net/ipv4/ip_forward

iptables -Z
iptables -F
iptables -t nat         -F PREROUTING
iptables -t nat         -F OUTPUT
iptables -t nat         -F POSTROUTING
iptables -t mangle      -F PREROUTING
iptables -t mangle      -F OUTPUT
iptables -X
iptables -P INPUT       ACCEPT
iptables -P FORWARD     ACCEPT
iptables -P OUTPUT      ACCEPT

}

# Begin firewall.status

statusFirewall() {

echo "iptables.mangling:"
iptables -t mangle  -v -L -n --line-numbers

echo
echo "iptables.nat:"
iptables -t nat	    -v -L -n --line-numbers

echo
echo "iptables.filter:"
iptables	    -v -L -n --line-numbers

# End firewall.status

}

case $1 in
 start)
 stopFirewall
 startFirewall
 ;;
 stop)
 stopFirewall
 ;;
 status)
 statusFirewall
 ;;
 restart)
 stopFirewall
 startFirewall
 ;;
 *)
 echo "Usage: sh myfirewall.sh { start | stop | restart } "
 ;;
