Norton, Bitdefender, and Malwarebytes have tailored their antivirus offerings to address a growing concern among gamers: the impact of security software on gaming performance. In June 2026, both Norton 360 and Bitdefender Total Security 27.0 achieved perfect scores from AV-TEST, while Malwarebytes demonstrated a 100% real-world protection rate in AV-Comparatives’ testing, albeit with a higher false-positive rate. Despite similar scores, the gaming experience varies significantly across these platforms.
Norton 360 for Gamers vs Bitdefender Total Security vs Malwarebytes Premium: quick verdict
For most PC gamers, Bitdefender Total Security emerges as the top choice in September 2026. Its combination of Autopilot and Game Profile minimizes frame-rate impact, registering only a 0-2% decrease during gameplay, and it matches Norton’s perfect AV-TEST score. Norton 360 for Gamers offers valuable features for streamers and competitive players, including a no-log VPN and gamer-tag dark web monitoring, but comes with a notable price increase upon renewal. Malwarebytes Premium stands out for its minimal resource usage, but its behavior-based scanning may compromise real-time file coverage.
Why gamers need dedicated antivirus in 2026
As gaming accounts hold significant monetary value, they have become prime targets for cybercriminals. Recent reports indicate that infostealer campaigns have surged, with malware like Vidar 2.0 capturing a substantial share of gaming-related threats. The FBI is currently investigating a campaign that exploited infected Steam titles to harvest sensitive data. Choosing the right security suite is crucial, as the stakes are higher than ever.

FPS and performance benchmarks compared
Performance remains a critical factor for gamers. In testing with Cyberpunk 2077, Norton exhibited a 2-3% average FPS drop, while Bitdefender’s Game Profile resulted in a mere 0-2% decrease, with some lab tests showing as low as 1.1%. Malwarebytes recorded the least impact, under 1%, thanks to its lightweight scanning architecture.
Malware and threat detection accuracy
In terms of malware detection, Norton and Bitdefender are tied at the top, both achieving perfect scores in AV-TEST evaluations. Malwarebytes, while effective, showed a higher false-positive rate in its real-world tests, which could pose challenges for gamers using unconventional tools.
Real-world examples: how each suite handles actual gaming threats
- The Steam indie-game malware campaign: This campaign distributed credential-stealing malware through indie titles, highlighting the importance of behavior-based detection.
- Discord-native stealers Katz and Bee: These malware families specifically target gaming platforms, making continuous real-time monitoring essential.
- The Lumma, Vidar, and StealC stealer wave: These infostealers have been linked to millions of stolen credentials, underscoring the need for robust detection capabilities.
Detection technology: how each engine actually works
The underlying technology of each antivirus product informs its performance and detection capabilities. Norton employs a hybrid model that combines signature-based detection with heuristic analysis, while Bitdefender leverages cloud-based scanning to minimize local resource usage. Malwarebytes focuses on behavior-based detection, which, while lightweight, may result in delayed responses to certain threats.
Feature-by-feature breakdown
Game-aware performance modes
