I've recently started using Norton firewall and am
surprised to see how many "pings" my computer gets in my
activity log. Most of the pings are "unused port blocking
has blocked communications". But several times a day,
more so just recently, my computer is being attacked
by "Backdoor Subseven Trojan Horse". The firewall blocks
the communication, but it's been happening 15-20 times
per day (it used to only be a couple times each day).
I've also been running Norton anti-virus with a Live
update. It hasn't detected anything on my computer. Is
there a chance that this Trojan horse is coming from
within my machine and Norton hasn't picked up on it? Or
are all these coming from other computers hitting my IP?
I've noticed that many of the IP's attacking mine are the
same. I've checked them with arin (whois?) but what does
that info tell me? Can I report them anywhere? How? I'm
grateful that the attacks are being blocked, but I'm
tired of constantly closing the high-alert window every
time it happens. Any advice on what to do now that I know
their IP? Thanks!
