Why not? What possible reason can you have for not wanting to apply fixes to your computer?
That's what firewalls do. Even a cheap NAT router will block all incoming traffic except that which is responses to your outbound connections. Even the built-in firewall in XP does this, now even better with SP2 being officially released (at least here in the US).
A firewall does not do this type of inspection. That's what anti-virus software is for. Granted, some firewall appliances does look for viruses, this is not usually a job for firewalls.
Bad idea.
There are no need to search for patches every day. Enable "Automatic updates" on your computer, and simply wait for the updates to come to you.
No, they intercept the virus before it's stored on your hard drive. Say you want to download a file to the c:/temp directory, and it contain a virus. As soon as your file are ready to be saved in this location, the anti-virus software will intercept it and remove the file from that location.
Yes, but very inefficient, as the data stream may be very long and slow, and your firewall software will have to piece together all the packets to make such a determination. That means it'll need a large amount of cache (either in memory or disk) to temporarily store this data while at the same time also handling other traffic in and out. And, if this is a software solution running on your desktop computer, then you already have the problem of the virus being stored on your computer (in the firewalls cache) before it's actually deleted.
Firewalls and anti-virus doesn't belong together.
