Firewall for Windows Vista

[Sidney]

You can lead a horse to water but you cannot make him drink.
The scam software known as Hackerproof98 had its name changed to Lockdown 2000.
Hackerproof98, sold under the company name Byte Tight Security, was a direct copy of a freeware program originally named NetWatcherPro. A monitor for Windows file shares.
It started out as a simple freeware program which was not anything approaching a firewall.
All these variations of this freeware program were peddled by the same scam artist.
Whatever name it was sold under it was a scam, totally useless.
If you regard that as a solid firewall then good luck to you.
