How to choose
Choose Bitdefender Total Security if you need to protect 5 devices (Windows, Mac, Android, iOS) for ~PHP 2,000/year. Kaspersky Premium covers 3 devices for ~PHP 2,500/year, making it less cost-effective for large families.
Gamers should avoid Norton 360 Deluxe, which is rated 'too resource-heavy' and has 'Medium-High' performance impact. Kaspersky Premium and Microsoft Defender offer low performance impact, with Defender using only idle CPU cycles.
If dark web monitoring and identity theft protection are priorities, Norton 360 Deluxe is the standout choice. Kaspersky Premium offers a data leak checker for credentials, while Bitdefender focuses more on parental controls and password management.
Microsoft Defender is free but lacks bundled extras. Bitdefender is ~PHP 2,000/year but has higher renewal prices. Malwarebytes is USD 45/year but functions best as a supplement rather than a standalone suite.

Bitdefender Total Security is the best overall antivirus for Windows 11 in 2026 due to its 99.9% detection rate, ransomware rollback, and comprehensive feature set for 5 devices. For those prioritizing identity protection over performance, Norton 360 Deluxe is a strong alternative despite its higher resource usage.
