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.

Best Antivirus for Windows 2026: 5 to Install, 1 to Avoid

Windows is the only desktop platform where antivirus software is essential. Microsoft has patched many vulnerabilities, but the OS still allows installations from unverified sources and connects to potentially untrustworthy networks. As of 2026, the top antivirus solutions for Windows include: - Norton 360: Best overall, with a full scan time of 13 minutes and 22 seconds, robust firewall, and up to 250 GB cloud backup. - Bitdefender: Best for older PCs, maintaining peak CPU usage at 11% and memory at 183 MB during scans. - Avast One: Best free option for Windows 11, achieving a perfect score in AV-TEST. - NordVPN Threat Protection Pro: Best for VPN users, blocking 90% of malware. - McAfee+: Best for households with multiple devices, offering unlimited coverage but is the slowest scanner. - Microsoft Defender: Best free option included with Windows, awarded Top Product by AV-TEST. Norton 360 has a 99.8% detection rate and offers a 60-day refund window. Bitdefender also has a 99.8% detection rate with low resource usage. Avast's free version is effective, while NordVPN provides integrated malware protection for existing VPN users. McAfee is suitable for large households but has slower performance. Microsoft Defender is adequate for single users practicing safe browsing but lacks multi-device support. Kaspersky is unavailable in the U.S. due to supply chain concerns.

Your Windows 11 PC is wasting RAM on 5 apps you probably don’t even use

Windows 11 has been criticized for being bloated, with several applications consuming excessive amounts of RAM without user consent. - The MSN Weather app can exceed 1GB of RAM shortly after launching, significantly impacting system memory. - The Widgets Board can consume several hundred megabytes of RAM depending on the displayed content. - Outlook, reliant on the WebView2 framework, can use hundreds of megabytes of RAM and remains active in the background, leading to unnecessary memory consumption. - Microsoft Edge often continues running in the background after being closed due to a feature called Startup Boost. - OneDrive is known for its background RAM consumption and potential memory leaks, making it advisable to uninstall for users who do not use it. Users with limited RAM should evaluate and uninstall default Windows applications that do not meet their needs to optimize performance.

Improving Lakebase Postgres compute cache

Lakebase Postgres employs a disaggregated storage model that enhances data management through efficient caching, utilizing an object store like S3 for backups. The caching operates on two layers: within distributed storage for optimizing write and read performance, and on the Postgres compute side for ultra-fast access to frequently accessed pages. Traditional Postgres caching involves shared buffers and the OS page cache, which leads to double buffering and inefficiencies. Lakebase Postgres addresses these issues by implementing a local file cache (LFC) and larger shared buffers, allowing for more effective memory utilization without the drawbacks of the OS page cache. The shared buffers are set to a maximum of 1 GB, while the LFC can utilize up to 75% of DRAM. The introduction of huge pages reduces memory management overhead and improves performance, resulting in significant throughput increases and reduced latency in production environments. Recent enhancements have shown up to 2× throughput improvements and substantial reductions in CPU usage. The focus is now on extending these benefits to autoscaling Postgres computes, with plans to implement dynamic shared buffers and autoscaling huge pages.

Windows 11 is accused of using AI to slow your PC, but it’s not what you think

Windows 11's privacy settings have caused confusion among users regarding the Text and image generation feature, leading to misconceptions that AI processes are actively running and draining system resources. Screenshots showing "zero" requests in the Recent activity section indicate that these features are not consuming RAM. The privacy page is intended to inform users about which applications can use on-device generative AI models, but it does not imply that these applications are currently using AI. The processing occurs on a specialized chip, ensuring that it does not burden the CPU, GPU, or standard RAM. Users can disable the feature by navigating to Settings > Privacy & security > Text and image generation. The terminology used in the operating system has contributed to misunderstandings, and the setting was enabled by default, which has led to skepticism among users due to Microsoft's history of implementing features without clear communication.
