I tested AVG antivirus. It’s proof great AV doesn’t need to be pricey

The cost of AVG Internet Security includes a single-device plan starting at a specified amount for the first year, which then increases to a higher annual fee, and a multi-device plan for up to ten devices that starts at a different amount for the first year and rises to a specified annual fee thereafter. The multi-device option allows sharing among family members. AVG Internet Security adds five features to its free antivirus: password protection, webcam safeguards, monitoring for unauthorized file access, defense against malicious website redirects, and protection against remote desktop protocol attacks. It does not include a VPN, which requires an upgrade or separate purchase. The installation process is straightforward, with a user-friendly dashboard. Users can initiate scans easily and choose from various scan types. AVG excels in real-time protection, scanning files upon access and monitoring applications for unusual behavior, including ransomware protection. As of 2025, users must set their own scheduled scans. AVG offers a secure browser during installation and a data shredder feature, though its effectiveness may vary. Customer support includes online chat, phone assistance, and comprehensive support pages. AVG Internet Security has received high marks for performance, detecting 100% of threats in controlled tests while minimally impacting system resources during regular use.

Hacker tracks Australian police using Android app

Australian police officers can potentially be tracked through publicly available Bluetooth applications due to a design flaw in tasers and body-worn cameras manufactured by Axon. A hacker demonstrated this vulnerability by using Android apps to detect nearby Bluetooth devices, revealing the location of police equipment, including model and serial numbers. The flaw arises from the failure to implement MAC address randomization, which could enhance security. The hacker developed software capable of tracking devices from over 400 meters away, raising concerns about the potential for criminal activities targeting police. Despite warnings to various police agencies, responses indicated confidence in existing security measures, although similar risks have been noted in the US, leading to the cessation of Axon body camera use by US Border Patrol agents. The vulnerability is considered a hardware-level issue, requiring significant redesign efforts from Axon to address it.

Wiz ZeroDay.Cloud Event Reveals 20-Year-Old PostgreSQL Vulnerabilities

Cybersecurity researchers at Wiz’s ZeroDay.Cloud event in London exploited two significant vulnerabilities in PostgreSQL, tracked as CVE-2026-2005 and CVE-2026-2006, which were disclosed on May 4, 2026. The vulnerabilities were found in the pgcrypto extension, affecting public-key decryption and symmetric decryption functions. CVE-2026-2005 allows privilege escalation via a buffer overflow during public-key decryption, while CVE-2026-2006 enables attackers to corrupt memory through inadequate checks in symmetric decryption. PostgreSQL has released patches for these vulnerabilities across versions 14.21 to 18.2, and MariaDB addressed a related issue in versions 11.4.10 and 11.8.6. Database administrators are advised to apply updates and audit logs for suspicious activity.

Are you still using Sign in with Google? Here’s why you should stop

Relying on a single Google account for access to various services poses significant vulnerabilities, including the risk of account lockout due to forgotten credentials, phishing attacks, or arbitrary bans. This centralized approach can lead to loss of access to critical data and services. Sophisticated phishing techniques, such as Adversary-in-the-Middle (AiTM) attacks, can compromise account security by mimicking legitimate login screens. Additionally, linking multiple services through a Google account contributes to a comprehensive digital footprint that Google can analyze, raising privacy concerns. To enhance digital security, users are advised to create standalone accounts for various services and utilize password managers like KeePass, Bitwarden, and 1Password to maintain unique credentials.

How to easily encrypt files on an Android phone – and the free app I use to do it

File encryption is important for mobile security, allowing users to encrypt files for secure access and sharing. The OpenKeyChain app simplifies this process for Android users by utilizing public key encryption, which involves a private key on the recipient's device and a public key shared for sending encrypted files. To get started, users need an Android device and the OpenKeyChain app. They must create their own key and can import public keys from others. Files can be encrypted for other users or stored securely on the device or Google Drive. Encrypted files have a .gpg extension, and users can disguise them for added security. The decryption process involves selecting the encrypted file within the app.

Windows Defender Security Flaws Actively Exploited by Hackers

Three vulnerabilities in Microsoft Defender, known as BlueHammer (CVE-2026-33825), RedSun, and UnDefend, are being actively exploited by hackers. BlueHammer has been patched, while RedSun and UnDefend remain unpatched. The public release of exploit code has accelerated real-world attacks, affecting Windows 10, Windows 11, and Windows Server systems. Attackers have begun exploiting these vulnerabilities, leading to concerns about privilege escalation, disruption of security updates, and the rapid spread of attacks.

Windows 11’s Recall tool has been cracked open again, and Microsoft doesn’t see that as a problem

Alexander Hagenah has developed a tool called TotalRecall Reloaded that exploits a vulnerability in Microsoft's AI feature, Recall, which manages data. Recall was designed to store AI-generated insights but was found to potentially store sensitive information in plain text, prompting Microsoft to delay its rollout. The vulnerability lies in AIXHost.exe, which lacks essential security measures, allowing unauthorized processes to extract sensitive data, such as decrypted screenshots and metadata, after user authentication via Windows Hello. Microsoft has downplayed the risks, asserting that existing security controls mitigate unauthorized access. TotalRecall Reloaded is available on GitHub for further exploration.

Microsoft adds Windows protections for malicious Remote Desktop files

Microsoft has introduced new security measures for Windows 10 and Windows 11 to protect against phishing attacks that exploit Remote Desktop Protocol (RDP) connection files. These updates, part of the April 2026 cumulative updates (KB5082200, KB5083769, and KB5082052), include a one-time educational prompt for users upon first opening an RDP file, requiring acknowledgment of the associated risks. Subsequent attempts to open RDP files will display a security dialog with information about the file's publisher, the remote system address, and local resource redirections, with options disabled by default. If an RDP file is unsigned, a warning will indicate an "Unknown remote connection." These protections apply only to connections initiated through RDP files, not through the Windows Remote Desktop client, and can be temporarily disabled via the Windows Registry.
