I have a computer that uses windows 2000, its updated, and there is F-Secure installed.
Iv started to have announcements that F-Secure has stopped a Nmap scan.
The computer is behind a old router and its the only computer behind that router.

Now I have started to understand how to use nmap, I started to wonder, how someone can come true my router and start nmap scan in my home network.

Well I dont like it and I want to stop getting those announcements. and the only way is to find out how "he" does it and sthen edit modems settings.
