Avast! free version runs weekly. Mine is set for Sunday nights at 11:59 pm and shuts off the laptop when finished.
In addition, I use CCleaner, Defraggler to maintain all my computers. I haven't found a free firewall which can handle multiple computers on a home network, so I'm using Windows Defender for Win7. Is there anything better for free?
Windows 7's firewall is more than adequate. Also, it's likely that you have a router, which means you already have a hardware firewall, so you're in good shape.
