Kapersky Internet Security and Antivirus Review 2025

Kaspersky Anti-Virus features a user-friendly interface organized into four main sections: scan, database update, reports, and an on-screen keyboard. The on-screen keyboard enhances privacy when entering sensitive data, protecting against keyloggers. The Reports section provides an overview of scanning activities and includes data from the System Watcher feature, which can mitigate malware attacks. The Database Update section allows for automatic updates to keep the software current with the latest threats, with options for manual scheduling. The scan menu includes a Quick Scan that completes in about seven minutes and a Full Scan that can take several hours; both scans detected all actual malware during testing.

CCI dismisses complaint against Microsoft

The Competition Commission of India (CCI) has dismissed a complaint against Microsoft regarding the bundling of Microsoft Defender with the Windows operating system, stating there was no prima facie case of contravention of fair competition standards. The CCI's order, dated March 3, indicates that users are not required to use Microsoft Defender exclusively and that OEMs can pre-install alternative antivirus software. The CCI compared Microsoft's practices to those of other operating systems like macOS and ChromeOS, concluding there was no violation of the Competition Act. The regulator noted that the antivirus market remains competitive, with many established players thriving despite Microsoft's software.

New Winos4.0 Malware Targeting Windows via Fake Gaming Apps

Cybersecurity researchers at Fortinet’s FortiGuard Labs have identified a malware campaign named Winos4.0 that disguises itself as benign gaming applications targeting Microsoft Windows users. This malware framework is similar to threats like Cobalt Strike and Sliver. Users who download these applications inadvertently install Trojan horses that deploy the Winos4.0 framework, which has been found in various gaming-related tools. The malware appears to focus on the education sector, as indicated by its file description “校园政务” (Campus Administration). Winos4.0 is a re-engineered version of the Gh0stRat remote access trojan and consists of modular components for specific tasks. The attack begins with the retrieval of a BMP file from a remote server, leading to the extraction of a DLL file named “you.dll.” This file downloads additional files, including the main malicious file “libcef.dll,” which injects shellcode to establish a connection with a command and control (C2) server. The malware executes various tasks, such as monitoring system information and maintaining a connection to the C2 server. To protect against such threats, users are advised to download applications only from reputable sources, avoid third-party app stores, and scan new files before execution. Regular device scans are recommended, especially after downloading new content.

Hackers increasingly use Winos4.0 post-exploitation kit in attacks

Hackers are targeting Windows users with the Winos4.0 framework, which is distributed through seemingly harmless game-related applications. This toolkit has capabilities similar to well-known post-exploitation frameworks like Sliver and Cobalt Strike. Initially, a threat actor named Void Arachne attracted victims with modified software like VPNs and Google Chrome for the Chinese market, but recent tactics involve using games and game-related files. The infection process begins when a legitimate installer is executed, downloading a DLL file from “ad59t82g[.]com.” This triggers a multi-step infection process involving the download of a DLL named you.dll, which fetches additional files and modifies the Windows Registry for persistence. The second phase involves injected shellcode that loads APIs and connects to a command-and-control (C2) server, while the third phase retrieves encoded data from the C2 server. The final stage includes loading a login module that performs various malicious actions, such as collecting system information, checking for anti-virus software, gathering data on cryptocurrency wallet extensions, maintaining a backdoor connection to the C2 server, and exfiltrating sensitive information through methods like taking screenshots and stealing documents. Winos4.0 can identify various security tools, including Kaspersky, Avast, and Malwarebytes, allowing it to adjust its behavior based on the environment. Fortinet describes Winos4.0 as a powerful tool for controlling compromised systems, with reports from Fortinet and Trend Micro providing indicators of compromise (IoCs) related to this threat.

As Monster Hunter Wilds PC players fight horrible polygons and struggle to hit 60 FPS, Capcom says the game is “already in a more improved state compared to the beta”

The Monster Hunter Wilds beta is currently available on all platforms, but some PC players are experiencing performance issues, including graphical glitches and framerate struggles. These issues are attributed to bugs rather than fundamental performance problems, and Capcom has provided troubleshooting options for players. Recommendations include adding the game to anti-virus exceptions, granting administrative privileges, updating drivers, and verifying the game's Steam cache. Specific advice for stability issues includes deleting shader cache files and enabling 'GPU scheduling.' Players using NVIDIA DLSS should be cautious with changing the Upscaling Mode to avoid increased VRAM usage. Reports indicate that achieving or maintaining 60 FPS at 1080p or 1440p is challenging for users with outdated hardware, while stable performance is noted among those with RTX 3080 or 4070 GPUs. The game relies heavily on frame generation and upscaling, and CPU performance may also impact gameplay. Historical context shows that previous Monster Hunter titles faced similar performance challenges at launch but improved over time. A second beta test is expected in December or January, and players are encouraged to provide feedback and adjust graphics settings.
