Linux and viruses

Am I correct in understanding that because a certain port, open by default in Windows, is closed by default in Linux, Linux is less vulnerable to viruses? I thought of the question because a friend just sent me what I thought was a virus warning.

Well the problem is that a windows binary files wont actually run in Linux, so basically those well known viruses are to do nothing on a linux machine unless you open it with software like WINE which emulates a windows environment and even so they are kind of restricted in there too.

But the vulnerability created by open ports depends mainly on the application that has that port open... So for example you have VLC with the telnet interface which opens lets say port 200, if VLC is vulnerable to some exploit and the port IS open then an attacker can exploit your computer be it windows or linux, thats why your assumption is partially correct. Your linux computer IS less vulnerable when those ports are closed but so is a windows machine.
