Microsoft has identified a memory corruption vulnerability in its Scripting Engine, designated as CVE-2025-30397. This vulnerability allows unauthorized remote code execution and is classified as “Important” under CWE-843 (Type Confusion). It was disclosed in the May 2025 Patch Tuesday updates and arises from improper handling of resource types. Exploitation occurs when a user clicks a specially crafted URL in Microsoft Edge's Internet Explorer Mode, potentially compromising system confidentiality, integrity, and availability. Although the attack complexity is high, successful exploitation has been confirmed in the wild. Microsoft has issued patches for all supported Windows versions, and users are advised to apply these updates and consider disabling Internet Explorer Mode to reduce risk.

Google is implementing new features to enhance security for Android users against phone call scams. Users will be restricted from sideloading applications or granting sensitive permissions while on a call with an unknown contact, receiving a notification that states, “This setting is blocked to protect your device.” Google has also prevented users from disabling its Play Protect security service during calls. These measures are available for devices running Android 16. Additionally, Google is piloting a feature for banking apps in the UK that alerts users of a “likely scam” when accessing these apps while sharing their screen with an unknown caller. Users can choose to end the call or face a 30-second delay before accessing their banking app’s screen. This feature will roll out for devices running Android 11 and newer. These updates build on existing scam protection tools, including AI that identifies potential scam callers and integrates scam detection into Google Messages.

The current landscape of artificial intelligence interactions includes cloud-based tools like ChatGPT and Copilot, but some users, especially developers, prefer running large language models (LLMs) locally. Ollama provides a solution for this preference. To run LLMs effectively, hardware requirements include a GPU, with larger models needing more computational power. For example, Google's Gemma 3 has a 1 billion parameter model requiring 2.3GB of VRAM and a 4 billion parameter version needing over 9GB. Meta's Llama 3.2 has similar requirements. A modern PC with at least 8GB of RAM and a dedicated GPU can utilize Ollama. To install Ollama on Windows 11, users download the installer from the official website or GitHub and follow the installation process. Once installed, it operates in the background, indicated by an icon in the taskbar, and can be accessed via localhost:11434 in a web browser. Ollama primarily uses a command-line interface (CLI), requiring users to use PowerShell or WSL. Key commands include "ollama pull" to install LLMs and "ollama run" to execute them. For instance, to install the 1 billion parameter Google Gemma 3 LLM, users would enter "ollama pull gemma3:1b". Running the models opens a chatbot interface for user interaction, and exiting can be done by typing "/bye". Setting up Ollama is user-friendly and requires minimal technical expertise.

Microsoft has lifted an upgrade block that prevented certain users of the Safe Exam Browser from installing the Windows 11 2024 Update due to compatibility concerns. The block was initially implemented in September to protect users from issues with Safe Exam Browser version 3.7 or earlier. Users are encouraged to upgrade to Safe Exam Browser version 3.8 or later before proceeding with the Windows 11 24H2 update. If users still encounter the safeguard hold after 48 hours of updating, they should contact Safe Exam Browser Support. The Windows 11 24H2 feature update is now available for all compatible PCs, except those under safeguard holds. Microsoft has resolved issues that previously blocked the update for some users and has removed other compatibility holds for specific devices and applications. However, some upgrade blocks remain due to incompatible hardware and software. Windows 11 24H2 began its rollout in May 2024 for enterprise testing, with a broader release in October.

Google is deploying advanced artificial intelligence to identify and combat online scams across its platforms, including Chrome, Search, and Android. The AI technology enables Google to detect 20 times more scam-related pages than before. Chrome will now alert users to unwanted or harmful notifications from scam websites, allowing them to unsubscribe or view blocked content. The initiative utilizes Gemini's Nano, an on-device AI capable of identifying new scams. Google has also introduced AI-powered scam detection in Google Messages, which flags potential malicious users by scanning for scam-related phrases and patterns, allowing users to report and block suspicious contacts.

Antivirus software has been essential for PC users for two decades, with advertisements emphasizing its importance. Windows 11 includes built-in security features, but many users prefer third-party antivirus solutions for quicker updates and additional benefits. User behavior significantly impacts computer security, and it is recommended to avoid links from unfamiliar email senders and not to reuse passwords. A comprehensive evaluation of antivirus applications involved testing on a Windows 11 PC using simulated virus attacks. The testing included scanning the SSD and consulting independent security testing laboratories. The best antivirus software for 2025 includes BitDefender Total Security as the best overall, Avira Free as the best free option, Malwarebytes Plus for the best VPN bundle, and Sophos Home Premium for protecting multiple devices.

pgpro_pwr is a database workload monitoring tool for database administrators (DBAs) to identify resource-demanding operations. It was launched in 2017 as pg_profile by Andrey Zubkov, who moved from being a DBA to an engineer at Postgres Professional. pg_profile is compatible with open-source PostgreSQL and has been integrated into PostgreSQL 17 as of 2024, while pgpro_pwr offers advanced statistical insights and is included in Postgres Pro releases. Both tools monitor database workload metrics through continuously incrementing counters, capturing values at intervals and archiving differences. They do not provide alerting capabilities but are useful for assessing system stability, analyzing load testing outcomes, and identifying system-intensive activities. The tools consist of repository tables, data collection functions, reporting functions, and service tables. To use them, one must install the extension, configure roles, and set up parameters. Reports can be generated for workload statistics over time and comparisons between different time intervals. Examples of report types include wait event statistics and advanced vacuum statistics. Future plans include submitting a patch to introduce vacuum statistics to vanilla PostgreSQL.

Google has announced a new security feature for Chrome on Android that uses machine learning through its Gemini intelligence to alert users about potential scams, spam, and unwanted notifications from malicious websites. This update allows Chrome to analyze website notifications more effectively, enhancing user protection. In September, Google also updated Chrome's Safety Check for Android, which now includes improved background tasks, notification alerts, and scans for security risks in passwords and installed extensions. The machine learning model was trained using synthetic data evaluated against real notifications to ensure effectiveness. The enhancements aim to provide a stronger defense against online threats.
