Why gamers need dedicated antivirus in 2026
In 2026, the value of gaming accounts has escalated, making them prime targets for cybercriminals. Rare skins on Steam, ranked accounts on Riot, or large Discord servers can all be resold, leading to a surge in malware targeting gamers. The Vidar 2.0 infostealer campaigns alone accounted for a 41% detection share among gaming-related malware this year, highlighting the necessity for robust security measures. Recent breaches, such as the 610,000-account Roblox leak and the 23.6 million-user Gyazo breach, further underscore the importance of dedicated antivirus solutions.
New malware families like Katz and Bee have emerged, specifically designed to infiltrate Discord and gaming platforms. Katz, for instance, injects malicious JavaScript directly into Discord’s application files, complicating detection for traditional antivirus solutions. This evolving threat landscape necessitates antivirus products that are specifically tuned to the gaming environment, addressing risks associated with cracked installers, fake mods, and links shared in gaming communities.

FPS and performance benchmarks compared
Performance remains the central focus of this comparison. In testing conducted on Cyberpunk 2077 at 1440p with ray tracing enabled, Norton exhibited a 2-3% average FPS decrease compared to a system running without antivirus, while CPU usage during gaming sessions remained below 5%. This slight impact is attributed to Norton’s Game Optimizer, which maintains full real-time scanning but prioritizes resources for gaming processes.
Bitdefender’s approach, which leverages cloud-offloaded scanning, consistently results in the lowest FPS impact among the three. With Game Profile activated, independent tests revealed an FPS drop of only 0-2%, and in one lab scenario, just a 1.1% reduction—an imperceptible change during gameplay. This efficiency stems from Bitdefender’s strategy of deferring heavy local scans while a game is in progress.
Malwarebytes Premium recorded the least FPS impact overall, measuring under 1%. Its architecture relies on behavior-based detection and scheduled scans, resulting in minimal CPU usage during gameplay. However, this lighter footprint comes at the cost of less continuous real-time file inspection compared to Norton and Bitdefender.
Malware and threat detection accuracy
In terms of raw detection capabilities, Norton and Bitdefender are effectively tied at the top. Both achieved the maximum AV-TEST score of 18 out of 18 in the June 2026 testing round, demonstrating exceptional performance across protection, performance, and usability metrics. Bitdefender’s Total Security 27.0 matched this clean sweep, confirming the two vendors’ strong malware-catching abilities.
Malwarebytes, while not rated by AV-TEST, received commendation from AV-Comparatives, achieving a 100% real-world protection rate in its February and March 2026 tests, albeit with a higher false-positive count. Its offline detection rate stood at 92.4%, with an online detection rate of 98.3%. This indicates that while Malwarebytes performs well, its behavior-first model may occasionally flag legitimate files, which could be problematic for gamers using mod tools or third-party launchers.
How AV-TEST and AV-Comparatives actually score these products
The scores referenced in this comparison derive from two independent labs with distinct testing methodologies. AV-TEST evaluates Windows 11 machines monthly, categorizing results into protection, performance, and usability. A product must achieve at least 10 points to earn certification, making Norton and Bitdefender’s perfect scores indicative of their top-tier status.
AV-Comparatives, which evaluates Malwarebytes, employs a different approach. Its real-world protection test exposes products to live, in-the-wild threats over several weeks, while a separate malware protection test assesses detection rates against a static sample set. This divergence explains the different shapes of Malwarebytes’ results, with a 100% real-world protection rate alongside a lower offline detection rate.
Real-world examples: how each suite handles actual gaming threats
While lab scores provide a useful overview, they do not capture the full scope of the threat landscape. Here’s how these products have performed against real-world threats over the past year and a half:
- The Steam indie-game malware campaign: The FBI is investigating a campaign that distributed credential-stealing malware through indie titles on Steam. A behavior-based engine like those in Malwarebytes or Bitdefender is designed to catch such threats, as the malicious code often evades traditional signature detection.
- Discord-native stealers Katz and Bee: These malware families are specifically designed to target Discord and gaming platforms, with Katz injecting JavaScript directly into Discord’s client files. Continuous real-time monitoring from Norton and Bitdefender provides an advantage in detecting such threats.
- The Lumma, Vidar, and StealC wave: Bitdefender’s threat research indicates these infostealers are prevalent in the gaming community, with millions of victims. All three products include detection signatures for these families, but speed of detection against new variants is crucial.
- Roblox’s 610,000-account breach: While antivirus software cannot prevent initial breaches, Norton’s gamer-tag monitoring alerts users when their credentials resurface on the dark web, enabling timely password changes.
- The Gyazo image-hosting leak: This breach highlights that antivirus alone cannot cover every angle of account exposure. Pairing any of these products with account-level monitoring is essential for comprehensive security.
Detection technology: how each engine actually works
The architecture of each antivirus product explains the differences in performance and detection capabilities. Norton employs a hybrid model, combining continuous signature-based detection with heuristic analysis for unfamiliar files. Its Game Optimizer adjusts CPU allocation without pausing the detection layer during gaming sessions.
Bitdefender utilizes a cloud-dependent approach, offloading heavy signature comparisons to its cloud infrastructure. This strategy minimizes local CPU impact, allowing for smoother gameplay. Autopilot further enhances performance by deferring non-essential tasks during demanding applications.
Malwarebytes focuses on behavior-based detection, monitoring for typical malware actions rather than constant file-level signature matching. This results in a lighter resource footprint but may lead to delayed detection of certain threats compared to continuous scanning solutions.
