What is a firewall
A firewall is a piece of software or computer equipment which blocks access to your computer which could be otherwise obtained through your network connector. It can prevent someone in your own local network (all of your connected computers at home or all of your connected computers at work) from accessing your computer but more important is that it can prevent someone unknown from accessing your computer via the internet.
Zone Alarm is a very popular shareware software firewall for Windows based computers. It has largely been replaced now as Windows-7 and Windows-8 contain similar functionality and many anti-virus programs now also have built-in software firewalls. Most people (at least in Australia) connect to the internet through an ADSL modem which is also (usually) a firewall and this will provide reasonable protection for most people. However I suspect that USB modems (eg 3G or 4G dongles) DO NOT provide a firewall and so if you are connecting via this method and you are not using Windows Vista or Windows-7 then you probably should install something like Zone Alarm to protect yourself.
If you have Windows-7 or Windows-8 (or Windows-10) then you don't need to install any other firewall as the firewall in these versions of Windows is more than adequate.
If you use Windows Vista then you should upgrade to Windows-7 or Windows-8 as Vista is "a complete dog" of an operating system. Microsoft stopped supporting Vista years before it stopped supporting Windows-XP (which came out a long time before Vista) because it was so problematic.
If you have Windows-XP then we'd suggest installing Zone Alarm to help protect your computer. Microsoft no longer supports Windows-XP and there are a lot or people out there saying that you should IMMEDIATELY upgrade because of this but we think that this is an over reaction. Windows XP is just as safe now as it was when it was supported - it hasn't suddenly become less secure. The only difference is that there will be no more fixes or updates form Windows XP beyond what is already available.
I have misplaced, forgotten or do not know what my password to Zone Alarm is?
The ONLY way to remove a ZoneAlarm Plus/Pro password that is forgotten, corrupted, or will not work is to remove the database files associated with TrueVector, as follows.
Please note that this will remove your program permissions and Trusted Zone settings (so you may want to make note of them), but re- establishing them is a simple process; you will be prompted again for program access for all the applications that you use to access the local network or Internet.
If you are running Windows 98se, ME, 2000, or XP, reboot your system into either Safe Mode. The method is determined by your OS but normally either pressing F8 at the beep, or holding the control key during boot up works. For more information on rebooting your specific system in Safe Mode, click Start, then Help. Click the Search tab, and type in SAFE MODE. Double-click Start Windows in Safe Mode for the instructions. NOTE: Do NOT start ZA+/ZAP while in Safe Mode, or you will not be able to make the changes necessary.
Open the Internet Logs directory (in 98se/ME this will be
, in 2000 it will be
c:\winnt\internet logs, in Windows XP it could be either of these folders). If you need to keep a copy of old alerts, copy the ZAlog.txt file to another location first - then delete ALL files in this folder.
Empty your Recycle Bin.
Reboot your system.
