You need to allow the following processes in your firewall to perform outbound connections on TCP port 443 (HTTPS):
C:\Program Files (x86)\NoVirusThanks\NVT License Manager\NVTActivator.exe
C:\Program Files (x86)\NoVirusThanks\NVT License Manager\NVTLicenseManager.exe
C:\Program Files\NoVirusThanks\OSArmorDevSvc\OSArmorDevSvc.exe

C:\Program Files\NoVirusThanks\OSArmorDevSvc\
Then try to restart the PC and if problem persists, try to uninstall and re-install OSArmor.
It is possible your security software is blocking following processes:
C:\Program Files\NoVirusThanks\OSArmorDevSvc\OSArmorDevSvc.exe
C:\Program Files (x86)\NoVirusThanks\NVT License Manager\NVTLicenseManager.exe
C:\Program Files (x86)\NoVirusThanks\NVT License Manager\NVTActivator.exe

It will automatically import C:\ExportedSettings.ini
Just run OSArmorDevCfg.exe file with following parameters:
OSArmorDevCfg.exe /import "C:\ExportedSettings.ini" /keepfile
You need to run the above command with Administrator rights. If you omit the /keepfile parameter, the INI file will be removed after it has been imported.

Payments are securely handled by our partner FastSpring.
You can safely pay using PayPal or a credit card (Visa, MasterCard, etc).
Here you can find some of the possible reasons for the cases when a credit card is declined while you are trying to make a purchase via a FastSpring payment platform:

  • 1) Invalid credit card number or billing address was entered.
  • 2) Incorrect or expired credit card expiration date.
  • 3) A hold has been placed on the account. This happens sometimes when the credit card company detects a transaction they don’t believe fits your normal buying pattern and are concerned that it might be a fraud or a charge that you didn't authorize.
  • 4) A restriction may have been placed on the account. For example, the account may be set up to not be used outside the country in which the card was issued.
  • 5) Insufficient funds on the credit card.
  • 6) The amount exceeds the limit set for daily or internet purchases.

If your credit card is declined again after that you have checked all data is correct, you should try to call your bank (credit card issuer) to inquire about further details and see if they can help you understand why your credit card failed to make the payment.
On the checkout page, on the right sidebar "Your Payment" click on "Enter Promotional Code" link, then enter the coupon code and click the "Apply" button.
Possible due to Risk Analysis from FastSpring, you may need to contact them from this link. Scroll down and click on "Contact Support" button, fill all the required details and click on Next button to complete the request. Only FastSpring can allow a canceled or declined order due to Risk Analysis. Another possible solution would be to use a different email, a few users have reported problems using Tutanota emails.
When you purchase a license it has a validity of 365 days (1 year) from when you made the purchase. So for example, if you purchase 10 licenses on 20 September 2020 then they will be valid until 20 September 2021 (for 1 year).
They will expire normally after 1 year from when you made the purchase.
You can test our product for 30-days so you can purchase a license only if it meets your requirements. For this reason we do not offer a refund for purchased licenses.
When you purchase a license you actually subscribe to a yearly subscription that is automatically renewed every 1 year from the date of when the purchase was made. Your payment method (credit card) will be automatically rebilled before the subscription expires. You will be notified via email one week before the subscription will expire.
You can visit the Account Management (provided by FastSpring) web page to manage or cancel your subscription. Just enter your email used during the purchase, you will receive a link to manage your orders and subscriptions.
If you cancel your subscription you will not be re-billed on the next charge. Your subscription (license key) will still be considered valid by our product until it will expire.
We set the expiration date a few weeks after the payment date so in case an user has payment issues he/she still has 2 or 3 more weeks to fix the payment details/cards before the program will auto-terminate the renewal and set the license to expired due to payment issues. If you check the remained days it should say you have remained around 385 days instead of 365 (1 year) due to the above explaination.
We just save your email address and your IP address. All details inserted during the order and payment phase are safely handled by our partner FastSpring.
No, payments are securely handled by our partner FastSpring.
Yes you will receive an email 2 weeks and 1 week before subscription expires.

We do not officially support it anymore.
Windows 7 SP1, 8, 8.1, 10, 11 (32-bit & 64-bit).
Windows Server, 2008, 2012, 2016, 2019 (32 & 64-bit).
You need to update to Windows 7 SP1. The SP0 version is missing important updates that are required in order to run OSArmor. A possible workaround (untested) may be to install the Windows update KB2999226 (32-bit link, 64-bit link), then you will need to install VC 2015. However, most probably this will not work, best to install directly SP1.
Yes, if you change the display scaling size to, for example, 125% or 150% then you should close OSArmor GUI via the tray icon -> Exit and then re-open OSArmor GUI by clicking the Desktop icon or from Start -> Programs -> NoVirusThanks -> OSArmor.
Absolutely yes, our product is fully compatible with any other security software, it works fine with (just to name a few): Avira, ESET, Kaspersky, Malwarebytes, Avast, etc.
You should allow or exclude all .exe and .dll files located in the following folders:
C:\Program Files (x86)\NoVirusThanks\NVT License Manager\
C:\Program Files\NoVirusThanks\OSArmorDevSvc\
Make sure they are allowed or excluded in your other security software. Then try to restart the PC and if problem persists, try to uninstall and re-install OSArmor.
No, it generally uses less than 50 MB of memory, CPU usage is very low.
Yes, OSArmor has its drivers co-signed by Microsoft and supports Secure Boot.
Absolutely no, OSArmor works perfectly with UAC enabled (you should never disable UAC).
Nothing, just use the PC normally. OSArmor will protect your system in the background and will block suspicious processes behaviors automatically.
It will display a notification window and it will log the event in the .log file located here: C:\Program Files\NoVirusThanks\OSArmorDevSvc\Logs\
Via the tray-icon menu (right-click with the mouse) or via the GUI application.
Yes, the GUI is used only to show you notifications, the OSArmorDevSvc (service) will still protect your system in the background. You should check the log files to see what has been blocked when the GUI is not running.
With default settings enabled you gain a good additional layer of defense and most malware delivery methods are blocked: VBS/JS/VBE/WSF scripts, MS Word/Excel/PowerPoint/etc exploit payloads, COM/PIF processes, and much more. This way you drastically reduce the possibility of getting infected by ransowmare, malware and other pests that spread via emails, scripts, maldocs, etc. By enabling some or most of the Advanced options (recommended only to experts) you can increase the protection layer.
Writing custom rules to block processes is simple, check out this page for more information. To add or edit your custom block rules just right-click the OSArmor icon in the system tray and click on "Custom Block-Rules". It will open the CustomBlock.db file with Notepad so that you can start writing your custom block rules.
Exclusion rules work like custom block rules, check this page. To open the Exclusions Helper GUI right-click OSArmor icon in the system tray and click on "Manage Exclusions". It will open a GUI that will help you write exclusion rules. If you like to hand-write rules just click "Open Exclusions" to open the Exclusions.db file with Notepad.
This may happen in case other security software have blocked the execution of OSArmor or NVT License Manager processes, so make sure the following processes are allowed/excluded/whitelisted in your other security software or HIPS software:
C:\Program Files\NoVirusThanks\OSArmorDevSvc\NVTHelperProcess.exe
C:\Program Files\NoVirusThanks\OSArmorDevSvc\OSArmorDevSvc.exe
C:\Program Files (x86)\NoVirusThanks\NVT License Manager\NVTLicenseManager.exe
C:\Program Files (x86)\NoVirusThanks\NVT License Manager\NVTActivator.exe
Then restart the PC, if problem persists try to re-install OSArmor.

Another possible cause may be that the VC++ 2015 Redistributables (x86) failed to install in your system via OSArmor setup file. In this case, a simple fix is to manually download and install them in the system, here is the direct download link from Microsoft website: vc_redist.x86.exe. Then once they have been successfully installed, restart the PC (not required but may help) and then re-install OSArmor.
This happens if the OSArmor service (OSArmorDevSvc) is not running. Make sure OSArmorDevSvc is running and that it is not blocked by other security software. To do so, you need to allow or exclude the following .exe files in your other security software: C:\Program Files\NoVirusThanks\OSArmorDevSvc\OSArmorDevSvc.exe
C:\Program Files (x86)\NoVirusThanks\NVT License Manager\NVTLicenseManager.exe
C:\Program Files (x86)\NoVirusThanks\NVT License Manager\NVTActivator.exe
Then restart the PC, if problem persists try to re-install OSArmor.
