I don't know if this is the right place to ask,but here goes.
In the last 4 hours the netbus trojan (whatever that is ) has 'attacked' my pc over 200 times,luckily the norton anti virus has stopped so far.
What is causing this and should i be worried about it?
Can i do anything about it or should i forget about it and stop worrying?

thanks lads.

From the Cleaner database.

Netbus:
Created: August 13, 1999 Modified: December 14, 2003
Type: Client/Server

NetBus can find cached passwords, has full control over all windows, can capture video from a video input device, has a scheduler to run scripts on specified hosts at a certain time, and support for plugins.

Ports used are 12345, 12456 or 20034tcp.

Now you know what netbus does.

If you havent got a trojan cleaner try the housecalls online antivirus scanner which often picks up tojans that others miss.

A decent firewall should take care of it as well - the ports that this trojan uses can be blocked off.

I have a hardware firewall here - a Netgear FVS318. I just let it get on with life 'cos it locks everything down unless you specifically open it up. I regularly get reports from it advising something nasty has been trying to get in, out, wave it all about.

I also have wall to wall AV as well.
