I ran a scan at Norton and if you have your TCP/IP enabled on your net bios your comnputer can be gotten into :
Go to Network Connections
Go to local...properties
Highlight TCP/IP
Click on properties
click on advance
on top click on the wins tab
Go to netbios(bottom of page )
Disable
click ok
If you have a 1394 connection
I did the same there
This is for windows xp users
