Hello fiveeagles,
I'd recommend ZoneAlarm from that download page first of all - it's very good but sometimes doesn't work well with Home Networks - if that's the case with you, try downloading Sygate instead. (All of them are free).
Avast AntiVirus can be downloaded here:

It's one of the best free AntiVirus programs I know.
