Anyone can perform a port-scan on any known computer at any time. If
you ever install a firewall (software or hardware) you will very quickly
find this out!

Anytime you access any web-site, that site has the "IP address" of your
machine, as seen via the Internet (you will have a protected local IP if
you are behind a firewall, managed by the NAT = Network Address Table).

So, if you go to any unknown web-site, that site can do ANYTHING it wishes
with your computer-internet IP address, including forwarding it immediately
to any list of malicious hackers, who could proceed to portscan-at-will against
your machine (or firewall box).

Therefore, once again, DON'T go to web-sites you don't trust :-)

Here are some simple essential guidelines (you CAN trust this site, but how
would KNOW this? ask here .. if you trust posters to this group??
trust everyone, and trust noone !
