Is the firewall provided with windowsxp good enough?
Depends on your needs and situation.
For most people, it will be MORE than adequate and anything else would be a
pain. The current implementation of the XP ICF only blocks INCOMING
traffic. That means if you get a virus like sasser on your machine somehow,
you will be sending it out to other people and trying to infect them.
Essentially - it can make you into a Typhoid Mary character.
Look around, compare, learn. Don't base your decision strictly on a
question asked once in a newsgroup and a half-dozen answers. Use Google to
research on your own!
