Frequently asked questions

Why is my ESET product telling me that my license is unauthorized?

ESET licenses are preconfigured for the quantity of devices that they were originally purchased for.

We are able to detect if a license has been used on more than the allotted quantity of devices or if the license has been shared multiple times with unauthorized users.

What if I purchased a legitimate authorized ESET license?

If you purchased your ESET license from ESET.com, an authorized ESET reseller or a reputable third party vendor, you may have received this alert by mistake. Please locate your license information to ensure that your license is associated with a valid email address.

If you need additional help, an ESET live chat agent can help you resolve the issue here.

What will happen if I don't purchase an ESET license?

While ESET reserves the right to take legal action against the usage of unauthorized licenses, ESET will be disabling all licenses that are unauthorized or overused. At that time, your product will no longer function properly, leaving your computer or mobile device vulnerable to malware attacks.

How do I update my product with my new paid license?

Take advantage of the limited time offer above to purchase an authorized ESET product license. Enjoy full support and version/detection updates to ensure your computers and devices are protected against threats.

After you purchase your license, you will receive an email containing your new license key. Enter this information into your product to activate it.

*Malware removal services are available to current ESET customers that have an ESET product installed and running on the infected device(s) prior to the malware attack. Pre-existing malware is not covered with the free malware removal service.
