Thanks for your reply, db. I already understand, in a conceptual way,
what ports are and what a firewall does. From all the "general advice"
that I'm getting, though still appreciated, it seems that I am
struggling to make my question clear.
My question, as I have tried to explain, is about HOW malware can take
advantage of open ports. For this to be possible, there must be some
software on my PC that accepts and actions requests sent over the
Internet. Now, this may be some piece of software that I've
deliberately set up to run to perform some task, or it may be an
unintended vulnerability (essentially a bug). However, as I now
understand it, there is no inbuilt component of Windows that, by
default (i.e. without any action in my part), *intentionally* allows a
remote agent to perform any action on my PC over the Internet. If that
is wrong then please correct me.
