Firewall, which one works best?

[CincyJim]

I don't think you need to worry too much if people can ping you unless you're running a black ops datacentre or something. If the relevant ports are restricted/unrestricted then the firewall should be sufficient.

I was hacked/cracked, & I lost the data on two Hard Drives!

As Steve Gibson's site says; pings are a common way to be recognized & attacked.

I want to be invisible to the www.
