hi peps, a question for you, i have ntl broadband, and am running xp pro, i have norton 2003 firewall and antivirus installed.

i am constantly getting trojan horse attacks showing up as high risk on norton. i switck my pc on for around 5 hours a day and get about 5 high risk trojan horse attacks. can i buy a hardware firewall? a friend has mentioned buying a router (to act as a physical firewall)to solve this which i know nothing about. surely if i only have one pc a router is not the best option.
any ideas? thanks! ;)

Ramification ,your firewall is doing its job , it is just alerting you to the fact that another computer is trying to scan your machine to see if it has a trojan installed on it that it can link to .

It is quite a common event , machines will scan a particular ISP at a time to look for vunerable machines hooked up to it .

Most people i know who have Norton Firewall have nothing but praise for it , cannot help you regarding a `hard` firewall , i just think it would probably be an unnecessary expense for home use , more intended for networks .

ok, yeah i also reckon norton is excellent but why are these attacks high risks? do you get as many attacks? my friends dont. i just had qhost trojan that norton didnt pick up n im quite worried.... thanks.

Switch the alerts off - they are probably nothing of the sort...

I am using Outpost Firewall (as recommended by the FE) I have never had an alert yet? Is it doing its job?

you can add a router to your setup .It would act as a gateway to WAN and people scanning around would get nothing back because all ports would be invisible .Router using NAT is a good hardware firewall for always on connection..IT just cost a few bucks to buy...

I am using Zona Alarm and I see that I have had 16 attacks rated as 'High' since switching on at 15.30 today. I don't know whether or not these would be a real threat but as cycoze says, at least the firewall is doing its job.

click here for a link to outpost firewall.P.S it is never a good idea to broadcast your email adress forum users can contact each other clicking the envelopes next to the names of the user.

is there an option in zone alarm where I can view a log of where the attacks are coming from??

ZA (especially) and Norton are totally OTT with their amusingly called 'alerts'. Turn off the alerts as they are a waste of time, just let the firewall do its job in the background. You will not get hacked on a home computer. I do not use firewalls as I suspect them to slow down surfing speed...but more of this at a later date.

To repeat some of my earlier info....You will NOT get hacked on a home computer. Hackers are not interested in the utter drivel that is on mine and everyone elses'. Firewalls??.they are useful in stopping Trojans dialing out but to be honest, if someone wanted to put a dialer on a computer it would not be rocket science. There are at least 5 programmes that can by-pass firewalls, 'TooLeaky' having the Gibsonmeisters' grudgingly awarded seal of entry. The Cult of the Dead Cows' Back Orifice, cheekily named after Microsofts' Back Office, could easily be put on a target computer, if one was really trying and the firewall would still be asleep. However. like my computer, most home computers contain utter drivel which is important to the owner but naff all use to the great unwashed. Bank and credit card details can be culled much easier than rooting through turgid files on a home computer. Hacking is not about breaking into home computers, it is about getting onto networks using passwords.

The 'alerts/attacks' are merely computers on the net asking your computer if it is still connected, these queries are called handshakes. When you are connected to the net you could be going through many servers and routers. This occurs in a millisecond, so you do not notice and all these routers and servers need to know that your computer is receiving, so that they can send images and webpages to your IP which is, in effect, your mailbox or receiving station. When on the Net you can pass through more than 20 servers and routers and they could all be handshaking your computer at short intervals. You will notice many of the 'alerts' come from Telecoms, which should come as no suprise as they own most of the routers etc.

If you were being hacked I can assure you that you would not get an alert.

Turn off all the alert buttons/warnings on your firewall safe in the knowledge that you will not be hacked. If it is any consolation I do not use a firewall on both my computers and I am on BB. I use a firewall on my laptop only because I take it to clients...so out of respect for their fears.......
