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.

Absolutely. You can download our anti-malware scanner first if you just want to run a quick check. While our free scanner does offer ongoing protection, our full internet security suite is advised for full protection.

Yes! ESET offers full protection against all forms of malware, including ransomware, spyware, keyloggers and adware. We use machine learning to stay up-to-date with new threats too.

We are committed to our clients’ 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.

You can renew, enlarge or upgrade your licence at any time. This keeps your product up to date, maintains your uninterrupted protection, and ensures you have free access to our technical support as well as loyalty benefits. 

1. Start by logging into your account using your license key (XXXX-XXXX-XXXX-XXXX-XXXX) or public licence ID.
2. To renew your licence, select the “Extend” option and adjust the period or number of devices you’d like to cover. Your renewal price will be pro-rated based volume discounts. 
3. If you want to add additional devices keeping the original expiration date, select “Enlarge” and adjust 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 licence has already expired. If this is the case, we recommend purchasing a new licence.

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

ESET auto-renew ensures that your ESET licences and products are always up to date, providing continuous, year-round protection. We handle the billing and renewal for you using auto-renew, and you’ll be entitled to special renewal pricing. 

By enabling auto-renew, 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 auto-renewal and renewal prices 30 days before your renewal date (for annual subscriptions) and after your subscription automatically renews, we will email you the transaction details. 

Auto-renew is continuous, unless you turn it off after your purchase, via your account. Turning off auto-renew 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 key (XXXX-XXXX-XXXX-XXXX-XXXX) or public licence ID. 
2. Proceed to the Licence Management page, where you may use the “Auto-Renew” slider to cancel the renewal of your subscription. 
3. Confirm your selection to renew manually.
