Most people connect to the Net through a router, usually supplied by
the ISP. By default, that router should not permit any connection
attempts. It is worth checking its configuration, in case some
'helpful' supplier has enabled uPnP 'to make it easier to play online
games'. If so, turn it off. 

Make sure router management is not permitted from the WAN side. Some
ISPs expect to be able to access the router from the Net, something
which should be discouraged.

If you haven't already, change the admin password from the default,
though you probably won't be able to change the account name.

If you use wi-fi, then use the best security your router and clients
can deal with, usually WPA2. If you don't use wi-fi, turn it off at the
router.

Really, with a router in its factory default condition, nothing from
outside should ever get as far as your computer. The problems don't
usually start until you want to run some kind of server software which
is accessible from outside, which must then be appropriately secured.

The main security issues, of course, come from connections you have
invited into your computer, malicious email and web pages. All you can
do to mitigate those threats is to be sensible and careful.
