DUH! Windows Defender is already running, performing scans late at
night, and works fine! I didn't even know it until I checked.
Minor point. Defender is an antispyware program, not a firewall.
Windows' firewall component is something seperate again, but this will also
be running by default.
I'm not a fan of Defender but it's a "good enough" spyware program, I guess.
I think there are better ones to be had, but it's adequate and obviously is
part of the cost of Windows and is already installed and running. I'd
suggest leaving it in place unless you yourself have reason to become
unhappy with it.
The Windows built-in firewall is also a perfectly adequate 'software
firewall'. Again, I'm fussy and feel that this whole class of products has
some inherent weaknesses, but in terms of protecting you against external
threats it is every bit as good as every other software firewall out there,
and again it's free.
Some software firewall products seem to feel the need to jump up and down
and tell you about how good they are, don't make the mistake that some do,
and believe a program that loves to talk about itself and its deeds is
actually any better than something that is happy to do the same job quietly
without needing to bother you every 10 minutes to pat it on the head.
