Security question

I'm wondering if it's at all possible to access someones HD with R/W priviliges over the internet if the target computer doesn't have any open FTP ports?

Im wondering because I've been hacked and I'm thinking of installing a firewall, but I'd rather not if I can just keep it secure by not having any FTP ports open.

    Yes, it is possible.

    Closing FTP ports will not help much. Remote-access via sockets is possible over any port, provided your pc is listening on a port (i.e. some software is listening for incoming connections)

    Trojans like SubSeven can do almost anything across the internet.

    Ok, I see. But as you said, some piece of software (a trojan) has to listen on a port, but that requires that the trojan is installed on the comp to begin with, right? If the system is clean and no programs are run on it other than the OS it should be fine? The system in question is actually a server on which I have all my backup files. It never actually runs anything except the OS and an FTP server.
