Your login might be marked as invalid due to various reasons. Here are a few common scenarios that could result in an invalid login:

1. Incorrect Identifier Entry: This occurs when there is a typing error in the Activation key or Public ID or other identifiers required for activation. Even a minor mistake can prevent successful validation.
2. Broken Link: If the link provided for subscription activation is broken or improperly formatted, the validation process cannot be completed successfully. If you copied the link, make sure it was selected correctly and in its entirety.
3. Multiple Manual Login Errors: Repeated unsuccessful attempts to manually log in using the information can trigger an invalid subscription status.

If you've double-checked your information and still face issues, please contact our support team. Provide any available subscription information and details about the problem you're encountering. Our support staff will be happy to assist you in resolving the issue promptly.

When you purchase a new subscription, you'll receive a brand-new Activation key. Simply update this key manually across your devices with ESET software. Your protection will be fully restored, just like before. This choice provides flexibility to adjust your subscription and device coverage as needed.

ESET offers compelling reasons to remain a part of our community:

• Speed: Our software is designed to ensure smooth operation, minimising disruptions to your workflow.
• Detection: We excel at identifying and removing the most sophisticated threats, providing robust protection.
• Usability: With an easy installation process, our set-and-forget solution simplifies your security management.

While we’d always recommend you have something rather than nothing, most free antivirus software won’t protect you from every single threat.

Our own free malware scanner is a great starting point, but to protect every aspect of your system from malicious software, data theft and more, you’ll need full coverage. ESET security software offers protection across multiple platforms & devices. It has anti-theft protection and security features designed to protect your financial data and personal information. Our technology also employs machine learning to help protect you from both existing and emerging threats.

Yes, ESET HOME Security Essential, ESET HOME Security Premium and ESET HOME Security Ultimate are multi-platform solutions. Use them to secure all your Windows, macOS and Android devices under one subscription—simply select how many devices you wish to protect, and enjoy powerful digital security.

ESET NOD32 Antivirus can secure desktop and notebook computers running Windows or macOS. 

We are committed to our customers’ satisfaction and therefore offer a generous 30-day return policy. If you are not 100% satisfied with your purchase, we will be happy to provide a full refund of the purchase price.

For more details, see our refund policy.

You can renew, enlarge or upgrade your subscription at any time.

1. Start by logging into your account using your licence/ activation key (XXXX-XXXX-XXXX-XXXX-XXXX).
2. To renew your subscription, select the “Extend” option and adjust the period or number of devices you’d like to cover.
3. If you wish to add additional devices under the original expiration date, select “Enlarge” and adjust the number of devices you’d like to cover. We’ll match the expiry date and calculate the pro-rated price for your extra devices.

If these options are not present in your account, it’s likely that your subscription has already expired. If this is the case, we recommend purchasing a new subscription.

If you are not sure how to renew or enlarge your subscription , please contact us for more support. 

By enabling automatic renewal, you agree that at the end of your licence period, we will automatically renew your licence using the payment details currently on file. For more details, see our auto-renewal policy.

We will inform you about upcoming automatic renewal prices 30 days before your renewal date (for annual subscriptions) and after your subscription automatically renews, we will email you the transaction details. 

Automatic renewal is continuous, unless you turn it off after your purchase, via your account. Turning off automatic renewal will not cancel your licence – your ESET protection will continue until your licence expires. We will notify you before licence expiration so that you may renew manually. 

You may cancel automatic renewal at any time. 

1. Start by logging into your account using your licence/ activation key (XXXX-XXXX-XXXX-XXXX-XXXX) or public licence ID. 
2. Proceed to the Licence Management page, where you may use the “Automatic renewal” slider to cancel the renewal of your subscription. 
3. Confirm your selection to renew manually.
