A Windows Defender bug is making VLC take 30 seconds to open an MP3 file

Jonathan Blow criticized the VLC media player for significant performance issues, specifically a 33-second delay in loading MP3 files, and announced his intention to switch to Microsoft Media Player. The VideoLAN team responded, attributing the delays to a known issue with Microsoft’s Windows Defender antivirus software, which quarantines the VLC plugin cache. They suggested users could resolve the issue by reinstalling VLC or regenerating the plugin cache. VLC has been downloaded over 6 billion times across various platforms. Microsoft Defender has been known to cause false positives and interfere with third-party applications. Some users have found success using alternative antivirus solutions like Bitdefender Antivirus Free to avoid conflicts with VLC. Additionally, there are suggestions that using VLC for MP3 playback may not be practical, and switching to Microsoft Media Player is viewed unfavorably compared to alternatives like Foobar2000.

4 Outdated Cybersecurity Tips That No Longer Keep You Safe

Creating robust passwords and storing them securely in a password manager is essential. Utilizing multi-factor authentication (MFA) is recommended for added security. Passwordless options like passkeys and security keys enhance convenience and security. Public Wi-Fi networks pose significant security risks, and caution is necessary when connecting. Hackers often use Man-in-the-Middle (MitM) attacks to intercept data on unsecured networks. Using a Virtual Private Network (VPN) can safeguard data by encrypting it before transmission. VPN routers can encrypt data for devices that cannot install a VPN. Traditional antivirus software may struggle against adaptive malware, which uses machine learning to evolve and evade detection. Companies are integrating machine learning into their antivirus solutions. Two-factor authentication (2FA) is commonly used but has diminished effectiveness due to new tactics employed by cybercriminals. Users should consider transitioning to passkeys and security keys for better protection against unauthorized access.

Best Antivirus for Mac 2026: Real Test Results and Ranking

Bitdefender Antivirus for Mac is the leading antivirus solution for Mac users in 2026, particularly effective on Apple Silicon and against live macOS threats. It achieved the highest malware detection rates, the fewest false alarms, and minimal impact on startup time. Other notable antivirus options include Norton 360 for Mac, Avast One for Mac, NordVPN Threat Protection Pro, McAfee Total Protection for Mac, and Malwarebytes for Mac.

‘This one just needs a script’: Researchers find ultimate Windows kill switch which can disable antivirus with almost no user interaction

Researchers have identified a significant vulnerability in consumer DDR4 and DDR5 memory modules, known as the “Download more RAM” flaw, which allows attackers to bypass advanced Windows security features, including Virtualization-Based Security (VBS) and Hypervisor Code Integrity (HVCI). This vulnerability enables the manipulation of configuration reports from RAM, misleading the system about its actual memory capacity, which can disable antivirus protections and allow the reintroduction of outdated drivers. The exploit can be executed via a single-click script, leading to security failures. Microsoft has released a patch for CVE‑2026‑23670 to enhance memory write protection against such exploits.

PSA: Don’t trust that Chrome update popup

Users of Chromium-based browsers, including Google Chrome, Brave, and Opera, are experiencing deceptive pop-ups that falsely claim a "Critical Update Required" or "Update available." These notifications are part of a scam designed to trick users into downloading malware disguised as software updates. Clicking on these prompts can lead to the download of harmful scripts, such as .vbs or .exe files, which traditional antivirus software often fails to detect. The issue is linked to compromised browser extensions that fetch malicious scripts from external servers. A specific extension, QuickLens – Search Screen with Google Lens, has been identified as a source of these pop-ups and has been removed from the Web Store. Other extensions, like “Enable Right Click & Copy Smart Unlock + OCR,” have also been implicated despite their popularity. Users are advised not to click on any links or run downloaded files and to check their browser settings for legitimate updates, as well as to audit and disable suspicious extensions.

Fake popular sites offer a free app, instead take over PCs

A fraudulent website mimicking CNN's homepage is promoting a fake "CNN app" that is not affiliated with CNN. This site, along with others impersonating brands like Avast and Stremio, distributes a legitimate remote management tool called O&O Syspectr, which can grant attackers remote access to victims' computers. The installers for these counterfeit apps share the same account ID, indicating they are linked to the same malicious source. Users are misled into downloading these installers, which appear legitimate but allow unauthorized access to their systems. O&O Software has responded by disabling certain features for free accounts and monitoring for abuse. Users are advised to only download software from official sources and verify installer details before execution.
