A few options:
1. Report them.
Note down the DNS numbers of the people who are targeting them and report them to their ISP (if you look up their ISP provider and then mail "abuse@insertnameofISPproviderhere.whatever
Problem with this is that it does nothing actually to solve your immediate issue of these alarms, is reliant on the ISP to take action, and the chances are that if these people are any good, they will be ghosting their DNS anyway (so they look like someone they are not when you trace it).
2. Permanently restrict these people.
I'm guessing you're running something like NIS or BlackIce ? If so, you can add individual IP addresses to a restricted zone, so that these people are blocked from any kind of connection to your computer. The problem is that if they are running a dynamic IP address (one that changes everytime they connect to the Interweb) or ghosting, then this doesn't stop them.
As Jon says, have faith in your firewall and just switch off the notification - make sure you keep it and Windows Update (assuming you running Windows) up to date.
4. Get a router.
Costs between £ 40 - £ 150 (depending on whether you want wireless or not), plug it into your computer, plug it into your phone line, it puts a physical seperation between your PC and the net, so if anyone tries to attack your computer, the only thing they can connect to is the router. Best and only solution IMHO for people who leave their PC regularly connected to the Internet for long periods of time.
Hope this helps
