Quote from a529612:
What can the hackers do if you have software firewall on your PC? Are you pretty much "naked" since you have to use his network?
I wouldn't be concerned about what they can or cannot do.
I would be concerned that its possible that a unsecured WiFi is intentionally setup as such by someone that wants to attermpt to gain access to any info you may have.
If you were just surfing the net on a unsecure connection...no big deal.
However, if your accessing info on your computer concerning financial or very private info...
Why take the chance when you have other solutions for a backup secure connection?
