You'll find a short profile for each product, who it's best for and how activation works after purchase (digital delivery by email). The comparisons focus on features and typical user needs rather than lab scores.

1The five profiles — quick overview

Below is a concise profile of each antivirus, highlighting the standout features and the ideal user. Where relevant we include links to the product page on Licensgo and short tips (e.g. backup, performance monitoring, webcam protection).

  • Norton 360 Deluxe — the most comprehensive option; includes unlimited VPN, a password manager, 50 GB of cloud backup and protection for up to 5 devices. Recommended for an all-in-one package; see the Norton 360 Deluxe licence and backup options in practical backups: quick strategies to avoid data loss.
  • McAfee Total Protection — identity protection; identity monitoring, firewall, secure VPN and device optimisation tools. Suitable if reducing the risk of identity theft is your priority.
  • ESET NOD32 Antivirus — the lightest option; minimal performance impact, anti-phishing and UEFI scanning, ideal for gaming and older PCs. A good choice for effective protection without slowing your system; see ESET NOD32 Antivirus and check resource usage with monitoring CPU, RAM and disk.
  • Avast Premium Security — for multiple devices; email and browsing anti-phishing, Wi-Fi and webcam protection, with support for up to 10 devices. Useful for sharing protection with your family; explore the Avast Premium Security licence and read how to protect your webcam and microphone on a Windows PC.
  • AVG Internet Security — the most balanced option; AI-powered detection, email and online banking protection, and an advanced firewall. Ideal for a mix of security, simplicity and value for money.
Quick tip

Match the product to your primary need: backup, identity protection, low resource use or many devices — don't choose by name alone.

2How to activate an antivirus bought from Licensgo

After purchase, you receive an email from Licensgo with the licence key and brief activation instructions. Activation typically takes a few minutes and happens inside the vendor app or account portal.

Examples: Norton and Avast commonly ask you to create or sign in to the vendor account and paste the key in the product interface; ESET may require registering the key on my.eset.com before activating on the device. If you need help, Licensgo support provides step‑by‑step assistance.

Fast activation

Keep your purchase email and follow the vendor's prompts. If activation fails, contact Licensgo with the order number for guided help.

3Where Microsoft Defender fits

Microsoft Defender (built into Windows) provides solid baseline protection: antivirus, firewall integration and cloud‑based threat detection. It's a valid primary defence for many users.

Limitations compared with commercial suites: Defender doesn't include an integrated VPN, a dedicated password manager, cloud backup quotas or comprehensive identity‑monitoring services — features some users prefer in the paid products above.

4Which one fits you?

Choose Norton 360 Deluxe if you want an all‑in‑one bundle (VPN, password manager, backup). Pick McAfee Total Protection if identity protection is your priority. Choose ESET NOD32 Antivirus for low impact on aged hardware or gaming. Opt for Avast Premium Security if you need coverage across many devices. Choose AVG Internet Security if you want a balanced option with AI detection and banking protection.
