5 popular programs that are destroying your PC’s performance

Modern web browsers, including Google Chrome, Microsoft Edge, and Firefox, are known for high RAM consumption, which can hinder performance, especially for users with multiple tabs. Alternatives like Arc, Vivaldi, Opera GX, or DuckDuckGo may offer lower resource usage. Third-party antivirus software, such as McAfee and Bitdefender, can slow down system performance, while Microsoft Defender provides adequate protection without the bloat. Wallpaper Engine, despite its appeal, can significantly drain resources on older systems, and users may benefit from lighter wallpapers or uninstalling it. SignalRGB, which syncs RGB components, is criticized for high resource consumption, and disabling it can improve performance. First-party vendor software, like Armoury Crate and iCUE, often comes with bloatware that consumes resources, and users can find more efficient alternatives. Identifying and addressing these resource-intensive applications can enhance overall system performance.

How Your Computer Protects Itself from Viruses and Cyberattacks

Virus protection is essential in the digital landscape due to threats like ransomware, phishing, spyware, and trojans that can compromise personal data and financial security. Cybercriminals continuously innovate, leading to potential malware infections that can steal sensitive information, lock files for ransom, or degrade device performance. Windows includes Microsoft Defender Antivirus, which provides real-time protection, automatic updates, cloud-based scanning, and firewall features. macOS offers built-in security tools such as XProtect, Gatekeeper, and the Malware Removal Tool, alongside regular updates. Linux distributions like Ubuntu are designed with security in mind, featuring regular patches, AppArmor, and optional antivirus tools. Key features to look for in antivirus software include real-time scanning, firewall protection, web protection, email scanning, automatic updates, and parental controls. While built-in solutions are often sufficient for everyday users, advanced users may benefit from third-party antivirus software. Best practices for maintaining cyber hygiene include keeping software updated, avoiding unverified applications, using strong passwords, enabling two-factor authentication, and regularly backing up data.

I learned these 6 antivirus myths for PCs are completely wrong

Antivirus software on Windows was once essential due to security vulnerabilities, but built-in protection in Windows 8 and later versions often suffices for everyday use. Modern third-party antivirus applications are designed to be efficient and have minimal impact on system performance. All operating systems, including macOS, Linux, iOS, and Android, are susceptible to malware, contrary to the belief that only Windows needs antivirus protection. Manual virus scans are no longer necessary as modern solutions provide real-time monitoring. Antivirus software should be part of a broader security strategy that includes regular updates and secure online practices. Relying solely on cautious behavior is insufficient, as threats can emerge from various sources. Using antivirus software is still recommended, and users can complement built-in security features with third-party solutions.

This new Defendnot trojan can get Windows to disable its own antivirus software

A researcher using the pseudonym es3n1n has created a tool called Defendnot that manipulates Windows operating systems to disable Microsoft Defender, making devices vulnerable to malware. Defendnot simulates the presence of a legitimate antivirus by using an undocumented API in the Windows Security Center, convincing Windows that a valid antivirus is installed. This development raises concerns about cybersecurity, as it undermines the effectiveness of built-in antivirus protections like Windows Defender.

Do You Really Need Antivirus on Windows 11? Probably Not—Here’s Why

Windows 11 has robust built-in security features that may reduce the need for third-party antivirus software. Windows Security now offers comprehensive protection, including real-time malware detection, firewall protection, SmartScreen alerts, hardware-level security, account monitoring, and system health reports. According to AV-TEST results from January and February 2025, Microsoft Defender Antivirus scored 6.0/6.0 in protection, performance, and usability, effectively stopping advanced malware and phishing attempts with minimal system resource usage. Users of Microsoft Edge benefit from SmartScreen filtering, while those using other browsers receive system notifications for network protection. Basic digital hygiene practices, such as avoiding suspicious downloads and keeping software updated, are crucial for security. Third-party antivirus solutions may offer additional features but can lead to performance issues and privacy concerns. For casual users who maintain their systems and practice safe browsing, Windows Security is generally sufficient, while those handling sensitive information or needing advanced features may consider premium antivirus options.

Defendnot — A New Tool That Disables Windows Defender by Posing as an Antivirus Solution

Defendnot is a tool that disables Windows Defender by using the Windows Security Center (WSC) API, presenting itself as a legitimate antivirus solution. It was created by a developer named “es3n1n” and follows the removal of a previous tool called “no-defender.” The tool engages directly with WSC, which disables Windows Defender when third-party antivirus software is installed to avoid conflicts. Defendnot was developed through reverse engineering of the WSC service and involves understanding how WSC verifies processes. It registers a phantom antivirus product using COM interfaces and undocumented Windows APIs, leading Windows to disable its built-in protection. The tool requires administrative privileges to operate and adds itself to autorun to maintain its functionality after a reboot. Security experts express concern about its potential misuse by malware authors, while it also provides insights into vulnerabilities in Microsoft’s security architecture.
