Norton 360 for Gamers vs Bitdefender vs Malwarebytes [2026]

Norton, Bitdefender, and Malwarebytes have adjusted their antivirus products to mitigate the negative effects on gaming performance. In June 2026, Norton 360 and Bitdefender Total Security both received a perfect AV-TEST score of 18 out of 18, while Malwarebytes achieved a 100% real-world protection rate in AV-Comparatives testing, though it had more false positives. Bitdefender Total Security is recommended for gamers due to its low frame-rate impact of 0-2%, while Norton 360 offers features for streamers and competitive players, and Malwarebytes serves as a lightweight secondary scanner. The value of gaming accounts has increased, making them targets for cybercriminals, with malware campaigns like Vidar 2.0 accounting for 41% of gaming-related malware detections. New malware families such as Katz and Bee specifically target Discord and gaming platforms. In terms of performance, Norton showed a 2-3% FPS decrease in Cyberpunk 2077, while Bitdefender's impact was only 0-2%, and Malwarebytes had less than 1% impact. Norton and Bitdefender are tied in detection capabilities, both scoring 18/18 in AV-TEST, while Malwarebytes had a 92.4% offline detection rate and 98.3% online. Norton includes a no-log VPN and gamer-tag monitoring, while Bitdefender offers identity protection without specific gamer-tag monitoring. Malwarebytes lacks a VPN and password manager. Pricing varies, with Norton starting at .99 for three devices, Bitdefender at .99 for one device, and Malwarebytes at .99 for one device. To switch antivirus solutions, users should back up their license keys, use removal tools, and ensure game-aware modes are active. Each product has unique strengths: Norton excels in gamer-tag monitoring, Bitdefender minimizes CPU usage, and Malwarebytes is lightweight but lacks additional features.

Microsoft Defender is causing slow VLC startups. Here’s the fix

Recent investigations have shown that a specific update to Microsoft Defender has caused performance issues for VLC Media Player, particularly a slowdown in startup times. Jean-Baptiste Kempf, a VideoLAN developer, attributed this sluggishness to a bug in the Microsoft Defender update, which quarantined VLC's plug-in cache. The problematic Defender signature update is version 1.455.50.0, linked to Windows Update KB5121003 released on August 11th. Users can reset the plug-in cache to improve performance by either reinstalling VLC or using the built-in functionality to regenerate the cache with vlc-cache-gen.exe. Alternatively, users can reset preferences and cache files by searching for "VLC" and selecting the reset option. Microsoft has not yet provided a fix for these issues, and users may need to set an exclusion in Microsoft Defender for VLC Media Player to prevent unnecessary scans, enhancing its performance.

Do You Really Need Antivirus in 2026?

The landscape of computer security has changed significantly over the past two decades. In 2026, antivirus protection remains important, but the need for separate third-party programs has decreased for many users due to the built-in Microsoft Defender in Windows 11, which is activated by default and effectively blocks 100% of common malware samples according to independent testing by AV-TEST. Windows 11 also includes additional protective features like SmartScreen and a robust Firewall. While dedicated security suites from companies like Norton and Bitdefender offer advanced functionalities, many users may find adequate protection with the built-in tools. Research from AV-Comparatives indicates that performance varies among security programs, particularly against real-world attacks. Phishing attacks accounted for approximately 60% of initial access points in incidents examined by the ENISA Threat Landscape report from 2025, highlighting that user behavior is a significant vulnerability. Modern web browsers and operating systems have enhanced their security measures, with Google Chrome, Microsoft Edge, macOS, and Android incorporating features to protect users from harmful websites and downloads. For the average Windows 11 user who keeps their system updated and practices safe browsing, built-in protection is generally sufficient, though paid antivirus options can provide additional tools.

Set Up Bitdefender Antivirus Free: 13 Steps [2026]

Bitdefender Antivirus Free was upgraded to version 27.0.62.355 on September 11, 2026, introducing a new Advanced Threat Defense driver that enhances behavioral monitoring capabilities. The free version is designed for Windows only and promises to remain free indefinitely, lacking features found in paid versions such as anti-tracking tools and a full vulnerability scanner. The installation requires Windows 10 or 11, at least 2GB of free disk space, a local administrator account, an active internet connection, and a Bitdefender Central account. Users must remove any existing antivirus software before installation, and the installation process typically takes 60 to 75 minutes. Bitdefender Free covers one Windows device and offers robust malware detection capabilities, particularly with the Advanced Threat Defense layer. It is recommended to schedule regular scans and check the Notification Center for quarantined items. If uninstalled, the dedicated uninstall tool should be used to avoid leftovers that could interfere with future installations.

8 Antivirus Software for Mac: Our Top Picks by Use Case (2026)

Apple provides built-in security features for macOS, including XProtect, Gatekeeper, and automatic malware removal, which contribute to the safety of Macs. However, these protections do not effectively address threats like infostealers, phishing, and adware. For enhanced security, third-party antivirus solutions are recommended. Bitdefender is noted for its strong detection rates and minimal system impact, making it suitable for most users. Intego specializes in Mac-specific threats and is ideal for users focused solely on Apple products. ESET and Trend Micro are recommended for businesses needing centralized management. F-Secure is recognized for its privacy-focused approach, while Norton offers a comprehensive suite of security features. AVG provides free real-time protection suitable for low-risk personal use, but may not be adequate for business needs. CleanMyMac is a maintenance tool rather than a traditional antivirus, focusing on system cleanup and optimization. Users should avoid running multiple real-time scanners simultaneously and ensure they purchase appropriate licenses for business use. It's important to evaluate the necessity of additional features and consider long-term pricing when selecting antivirus software.
