Gamers face a unique challenge: traditional antivirus software can cause system slowdowns during gameplay. This review tests the top antivirus products with a focus on their impact during gaming sessions in 2026.

Testing Methodology

FPS impact tested using Intel i9-14900K, RTX 4090, running Cyberpunk 2077, Fortnite, and Counter-Strike 2 at maximum settings. Impact measured using CapFrameX at 1080p and 1440p.

Results

1. Webroot SecureAnywhere: Zero FPS impact — cloud scanning has no measurable effect on gaming performance
2. ESET NOD32: Less than 1% FPS impact — minimal system footprint ideal for gaming PCs
3. F-Secure Total: 1-2% FPS impact — Gaming Mode automatically postpones non-critical scans
4. Bitdefender: 2-3% FPS impact — Gaming Profile mode significantly reduces background activity
5. Norton 360: 3-5% FPS impact — Norton Game Optimizer closes background processes to free up RAM and CPU

Best Gaming Security Features

• Game Mode: Suspends notifications, scans, and non-critical updates
• Process prioritization: Ensures game processes get CPU priority
• Full-screen detection: Automatically activates when games launch
• Low network impact: Minimal bandwidth usage during gaming sessions

Verdict

For gamers refusing to compromise performance, Webroot SecureAnywhere or ESET NOD32 are the clear winners with negligible system impact. Bitdefender and Norton offer the best compromise between gaming performance and comprehensive security.
