For a home pc (xp) for an average user?
I know updated AV is a must have and some sort of fire wall is a good idea.
Is it pratical to have a 2056 cipher file encryption program.
What are some simple methods of usuing an encrypted tunnel through the average broadband ISP? What would be the comman uses for this?
Are the built in firewalls and encrypted files and folders for xp considered strong enough?
What are comman security risks on say an average home xp system that should be corrected no matter what? besides the remote sharing service.
What would be considered staying secure and what would be considered over the edge?

I know that this is a lot of questions for one thread and don't expect them all to be answered in a sigle post. Just looking for some thought back by solid info.
