You NEED a Firewall
Today's devices are continually connected to the Internet so you cannot afford to be without a firewall. See Firewalls: Your First Line of Defense….
The nature of threats on the Internet has changed.
- Get to know how your security software warns you about threats.
- Newer threats are much harder to detect and very difficult to remove.
- Recovery from ransomware is unlikely. A reliable (uninfected) backup of your current data is the only recovery you can count on.
- Many websites are infected with programs that appear to be legitimate, but whose purpose is to scare you into downloading dangerous software.
- Many “free” download sites confuse users with multiple download links that are unrelated to the intended download, often retrieving malware instead.
Mobile Also Vulnerable
The massive move to mobile has led to huge increases in attacks on mobile devices. Android devices have been the hardest hit, but Apple iOS devices are also vulnerable.
And yet, while access to free Wi-Fi is a boon for most of us, it's also a common attack vector (entry point) for cybercriminals. …[C]onsider that public Wi-Fi, by its very nature, is open and unprotected to allow anyone to access it. That makes it vulnerable to hackers, and they have a variety of tools to attack devices on public Wi-Fi.

Trends have moved away from viruses to credential stuffing (hacking using repeated user name/password combinations), banking trojans, phishing, multifactor authentication and ransomware.
If you are a mobile user only (i.e., you don't own a computer) check out ZoneAlarm's Mobile Security app. It is available for both Android and iOS.
Paid or Free?
ZoneAlarm provides two basic classes of products:
- paid versions for which you need to purchase a licence; and
- free versions which are available at no charge (provided you can meet the licence requirements).
The freeware security packages make quite an impressive showing in the test, but anyone who wants the highest level of security is required to use one of the commercial packages.The free products tend to concentrate mostly on their pure protection function.

Upgrading to Windows 11?
If upgrading to Windows 11, it is strongly recommended that you uninstall all non-Microsoft security products (including ZoneAlarm) before upgrading.
Once the upgrade has completed successfully, you can reinstall ZoneAlarm Extreme NextGen (recommended) or ZoneAlarm Free Antivirus + Firewall.
Legacy ZoneAlarm products (version 15x) will NOT work on Windows 11.
Moving to ZoneAlarm Extreme NextGen is strongly recommended if you have an existing licence.
Obtaining ZoneAlarm
Ensure you choose the right product. You cannot install a different product over top the one currently installed.
Current Products
Current ZoneAlarm software includes
Both have been updated with a modern interface and are supported on Windows 11 starting with version 3.3.411.
Replacing ZoneAlarm Extreme Security
ZoneAlarm Extreme Security was declared a legacy product on May 13, 2022. This makes it unsafe to continue to use it.
Final Updates
The final update for ZoneAlarm Extreme Security (15.8.211.19229 on August 26, 2022) hardens security and provides bug fixes and improved stability.
Switching to NextGen Recommended
Extreme Security users will have to move to Extreme Security NextGen to remain supported. No purchase is required if your license is still valid.
Uninstall your current product, reboot, then install the new product.
NextGen requires the six-character “mobile” key (not the 31-character legacy key used by ZoneAlarm Extreme Security).
ZoneAlarm Extreme Security NextGen
ZoneAlarm Extreme Security NextGen for the complete security & privacy suite that guards you against the most sophisticated cyber threats and attacks. Supported on Windows 7/10/11, Android, iOS.
Enjoy enterprise-level security technology, adapted for home users and small businesses.
NextGen Advantages
Extreme Security NextGen is a new product that guards you against the most sophisticated cyber threats and attacks. It includes web content filtering, supports Edge and Firefox as well as Chrome, has an updated engine and a new modern interface.
ZoneAlarm Extreme Security NextGen supports Windows 7/10/11.
NextGen has a modern interface and is much simpler to use.
NextGen checks websites and web forms for malware and phishing attacks. This may slow the loading of pages slightly, but protects you from online threats.
Disadvantages
Customization options are fewer. NextGen lacks a gaming mode, keylogger and manual update option.
I would still recommend NextGen for most folks. It is much simpler to use and the hands-off approach is a bonus for non-technical users.
Why I Moved to Kaspersky
However, I found that NextGen does not meet my requirements.
NextGen quickly quarantined some file on my system without asking, then took well over a day to restore them. While these are files that should not be on most systems, I use them in recovering corrupt computers as part of my work as a consultant.
I chose to remove NextGen and replace it with Kaspersky Total Security (I had an existing subscription for my Mac). Kaspersky gives me the control I require — control that I used to have with the legacy versions of ZoneAlarm Extreme.

Installing & Updating ZoneAlarm
These instruction will help you to install or update ZoneAlarm smoothly and avoid issues.
The installation of major updates follows essentially the same process except that you seldom need to uninstall the current program or re-enter the license key.
Ensure Windows Update is Current
Installing ZoneAlarm while Windows Updates are pending can create conflicts.
Before beginning any ZoneAlarm installation:
- check for Windows Updates (Start ⇒ Settings ⇒ Updates);
- finish installing any pending updates; then
- restart the computer.
Preparing for the Installation
When installing ZoneAlarm, be sure you choose the right product:
ZoneAlarm Extreme Security NextGen requires that you purchase a license if you intend to use it after the trial period ends.
Download the Installer
You'll need to download the most recent version of the product you want to install. This download will update an existing installation of the same product.
Avoid Installing Multiple Security Products
ZoneAlarm isn't compatible with any other security software except MS Windows Defender.
Running multiple security products can appear as a threat to each other and, in the process, allow your computer to become infected and/or cause computer slowdowns.
To install ZoneAlarm, you must first uninstall other security software then restart your computer or you may experience OS stability and computer performance issues.
To install a different ZoneAlarm product you need to uninstall the existing product, restart Windows, then install the new product.
You can update the same ZoneAlarm product without removing it first.
Installing ZoneAlarm Extreme Security NextGen
Be sure that no other programs are running to avoid conflicts.
Double-click on the ZoneAlarm installer. ZoneAlarm downloads necessary files. Review the licence agreement, then select Agree. The installation continues:
A warning to uninstall the ZoneAlarm Web Secure Chrome extension may be displayed:
Since Chrome extensions are used by Microsoft Edge and other browsers like Opera and Vivaldi, you'll need to check those browsers for the extension as well.
Once the installation process is complete, you'll see the NextGen interface. Initially it is set up for a free 30-day trial:
Click on the green Activate button at the top left to activate ZoneAlarm Extreme NextGen with your six-character license key (purchase a license, if you haven't already).
Once entered, the program is activated and the red bar at the bottom is removed:
Installing ZoneAlarm Free Antivirus + Firewall
Be sure that no other programs are running to avoid conflicts.
Double-click on the ZoneAlarm installer. ZoneAlarm downloads necessary files. Review the licence agreement, then select Agree. The installation continues:
Once the installation process is complete, you'll see the ZoneAlarm Free Antivirus + Firewall interface:
Extra Features Require Activation
Web Secure and Anti-Ransomware protection are not included.
The “Buy Now” buttons will take you to ZoneAlarm's site to purchase ZoneAlarm Extreme Security NextGen.
Click on the green Activate button at the top left to activate the Web Secure and Anti-Ransomware options with your six-character license key:
Once activated, you will be running ZoneAlarm Extreme Security NextGen.
Configuring ZoneAlarm
ZoneAlarm Extreme Security NextGen and Free Antivirus + Firewall are much less complex than earlier legacy versions. Little user interaction is required for protection.
The interface is relatively plain, although you can make changes by clicking on one of the Antivirus, Firewall, Web Secure or Anti-Ransomware icons on the bottom.
Uninstalling ZoneAlarm
If you want to stop using ZoneAlarm, be sure to uninstall it properly.
Disabling ZoneAlarm Will Cause Problems
Disabling the startup of ZoneAlarm will cause you problems because it continues to run invisibly (ensuring that ZoneAlarm can't be disabled by malware).
Don't Manually Delete ZoneAlarm Program Folders
ZoneAlarm makes changes to your system that require it to be properly uninstalled, either from the uninstall program in the Zone Labs program group or by going to Settings and selecting Apps & Features.
ZoneAlarm Registry Entries
Some users have experienced difficulties when improperly uninstalling ZoneAlarm. Be sure to remove any relevant registry entries.
Improper changes to the Windows registry can make your computer inoperable. Make these changes carefully or seek out professional assistance.
Resolving ZoneAlarm Program Issues
If you have problems updating or maintaining ZoneAlarm, you may need to uninstall it, reboot, then reinstall the same version.
ZoneAlarm Extreme NextGen requires the six-character (mobile) key (not the 31-character legacy key used for ZoneAlarm Extreme Security).
Try the Windows Uninstaller First
First try uninstalling ZoneAlarm using the uninstaller built into Windows.
- The uninstaller is found in the Setting's Apps & Features (Control Panel's Programs and Features). You'll need to reboot Windows to complete the uninstall.
- You'll want to have a current copy of the correct version of ZoneAlarm for your licence.
- You'll need to reboot again when the installation is complete.
If ZoneAlarm was improperly uninstalled, you may need to reinstall it before uninstalling it again to complete the process successfully.
- Do not try to install a newer version of ZoneAlarm if you're having difficulties.
- Download and install the currently installed version for this process.
- You may need to contact ZoneAlarm support to obtain an older version.
Clean Install
If uninstalling then reinstalling ZoneAlarm didn't work, you'll need to download the ZoneAlarm removal tool (CLEAN.exe).
Running the removal tool completely removes the settings and changes made by ZoneAlarm. Reboot Windows when the process is complete.
Now install ZoneAlarm. Because the clean install removes ALL settings so you'll need to have your license key for ZoneAlarm Extreme Security NextGen.
Manual Removal
If the ZoneAlarm uninstaller AND the ZoneAlarm removal tool both fail you'll need to remove the program manually. This is not a task for novices. I suggest you contact ZoneAlarm support for help.
ZoneAlarm Issues
If your Antivirus updates have stopped working you will need to install the latest version of ZoneAlarm to correct the problem.
Windows 11
Only ZoneAlarm Extreme NextGen or ZoneAlarm Free Antivirus + Firewall are supported for Windows 11.
If upgrading to Windows 11, it is strongly recommended that you uninstall all ZoneAlarm products before upgrading. Once the upgrade has completed successfully, you can install ZoneAlarm.
ZoneAlarm Extreme NextGen requires the six-character (mobile) key (not the 31-character legacy key used for ZoneAlarm Extreme Security).
Conflicts with Security Software
ZoneAlarm isn't compatible with any other security software except MS Windows Defender.
To install ZoneAlarm, you must first uninstall other security software or you may experience OS stability and computer performance issues.
When multiple software firewall programs are installed, there is no way of ordering which firewall will get a packet and which will report it, the determination as to which product gets operating system preference to monitor the traffic will be made at random.When running more than one firewall, ZoneAlarm might not be able to report on incoming port scans or hack attempts.
In some cases, running two software firewalls at the same time can cause more problems than running only one.
— ZoneAlarm Support
Other Conflicting Programs
Some name-brand computers may run programs that prevent ZoneAlarm from loading or cause a blue screen error (BSOD). Tracking these down can be difficult.
Run MSconfig to stop all startup programs except ZoneAlarm to verify the problem is resolved. Restore the startup programs one-at-a-time until the program creating the conflict is determined. This is usually (but not always) a driver issue.
Disabling the problematic program using Piriform's CCleaner may be easier than via the MSconfig interface because a normal startup for Windows is possible.
- Open CCleaner, then click on the Tools icon and select Startup.
- Look for potentially problematic startup listings and disable their startup.
- Now restart Windows.
If your computer continues to function okay with the startup of the problem program disabled, then you've resolved the issue. You can restore the startup of disabled programs one at a time (rebooting in between) to determine if the problem returns, but only if you want those programs to run.
- Should I Remove It? can help you determine if you can safely disable a particular program.
Internet Access Issues
The most common reason people cannot access the Internet is because they have stopped ZoneAlarm from loading or have tried to delete ZoneAlarm's files without uninstalling ZoneAlarm properly. This can also happen if ZoneAlarm doesn't load correctly at startup.
By default, ZoneAlarm (like many security products) disables normal access to the Internet. This is how a firewall works
If ZoneAlarm is not running, it is unable to process permission for new programs to access the Internet. Programs that have been given access without asking (either a program recognized as safe by ZoneAlarm or configured manually by you) may continue to have access. An updated program may cease to work.
Other Reasons You Can't Access the Internet
There are additional potential causes for loss of Internet access including:
- Windows Firewall can stop access.
- Conflicting security software may disable access.
- Anti-malware can disable access for programs.
- Trojans and other malware (including programs that emulate antivirus software but are malware) usually disable your antivirus and access to security sites on the Web by making changes to the Proxy or Hosts file.
- The Windows Proxy has been tampered with (Start ⇒ Settings ⇒ Network & Internet ⇒ Proxy).
- Proxy should be set to “Automatically detect settings”
- Check with whoever manages your network to determine if other settings are required.
- Check your browser settings to see if the browser's proxy settings have been tampered with
- This is usually set to “use system proxy settings”.
- You may be able to restore access by changing this to “No proxy” temporarily while you resolve the issue.
- Check the Hosts file to see if it has been altered.
- There should only be comments (prefaced with the # symbol).
- Malicious programs usually change this to ensure you cannot find help on the Web.
Operating System Issues
When new versions of Windows are first released, ZoneAlarm (and other security software) may not work.
Because of the long Windows release candidate programs, ZoneAlarm is usually available for early Windows adopters (but not necessarily during the beta phase).
