PC security - what are the real threats?
On another thread, wifi security was mentioned as a reason for opting for a hard-wired ethernet connection.
So the question is this:
In a home office/domestic setting, what are the real threats to PC security, and what's a rough weighting of those threats? Assume that the user has standard security enabled on an XP Pro machine, a WEP- encrypted, firewalled wifi router, and does not respond to phishing/419 emails.
