I downloaded Nano antivirus pro, installed it, then the activation key is needed.
I put the given activation key but it is invalid. I followed all the given instructions
but I couldn’t enjoy it.

[@Afify Aly] We have verified the activation key. The key is valid and can be activated. Please try to activate the Antivirus again.

To activate NANO Antivirus using a key, do the following:
– select the Get a license online item and fill in the Name and E-mail fields (the fields cannot be empty!);
– go to the sub-item Activation key and enter your key;
– click the Get License button.
Note: the ability to insert a key is supported.

Hi, I can download the installer for Nano AntiVirus but when I reach for it after apparently installing it I cannot find it. Most installations offer to run after installation but this program does not?

Double click on the file to run it. The file can be found in the download folder of your browser.

It’s free just for 8 months. I installed it today, and I get the information that my license expires on 23/05/21!

The license for NANO Antivirus on your PC will expire on April 6, 2021. The information displayed in the Antivirus itself is incorrect. Let us explain in more detail why this is happening. For many programs, the license expiration date is directly based on the system date, i.e. if the user for some reason suddenly changed the system date (for example, a system failure occurred), the license validity period will also change. Thus, the user can be left completely unprotected. To prevent such situations, NANO Antivirus has a built-in mechanism for monitoring the license expiration date. Your situation is a side effect of our license expiration date control mechanism. Only the license expiration date displayed on your PC changes, the actual license expiration date is stored on our servers and remains unchanged. The license information will be updated when updating NANO Antivirus to a new version.

BULLSHIT SOFTWARE!!!!
