Do You Need Antivirus for Chromebook?

Chromebooks are designed with robust security features, including sandboxing, verified boot, and automatic updates, which contribute to their reputation as secure devices. Despite these protections, vulnerabilities can still exist, particularly through phishing scams, risky extensions, and the use of Linux or Android apps. Security experts suggest that users who frequently engage in online shopping, download Android applications, connect to public Wi-Fi, or store sensitive information in the cloud should consider antivirus software for added protection. Recommended antivirus options for Chromebooks include TotalAV Essential Antivirus, Norton Mobile Security, and Avira Antivirus Security, each offering various features and benefits tailored for Chromebook users.

AVG Antivirus Review 2025: Robust Free Version but Middling Premium Plans

AVG Antivirus offers a freemium model with a suite of cybersecurity tools. The Ultimate plan scored 7.6/10 overall, with the following breakdown: Performance 9/10, Security 7/10, Customer Support 7/10, Usability 9/10, Value 7/10, and Features 7/10. The free version includes scan scheduling and protection against ransomware, while the paid AVG Internet Security covers up to 10 devices. AVG Ultimate includes a VPN and performance tools but lacks some advanced privacy features found in competitors. Usability testing showed intuitive account navigation, though installation was complex. AVG's antivirus engine achieved a 99.3% online detection rate, but there are concerns about data-sharing policies and past breaches. Customer support includes a knowledge base and 24/7 live chat, but experiences were often unsatisfactory. AVG's pricing is competitive, especially for its free option, but may not meet the needs of users requiring advanced features.

Hackers Use Fake Verification Prompt and Clickfix Technique to Deploy Fileless AsyncRAT

Threat actors are using a fileless variant of AsyncRAT, targeting German-speaking individuals with a deceptive verification prompt. This prompt misleads users into executing harmful commands. The malware employs obfuscated PowerShell scripts to operate in memory without creating files on disk, complicating detection by antivirus solutions. The attack begins with a fake verification page prompting users to click "I’m not a robot," which copies a malicious command to the clipboard. This command uses conhost.exe to run a hidden PowerShell instance that retrieves a payload from a remote server. The malware establishes a connection to a command-and-control server and maintains persistence through registry keys, enabling remote control and data exfiltration. Key tactics include stealth execution, in-memory C# compilation, and TCP-based communication over non-standard ports. The campaign has been active since at least April 2025. Indicators of Compromise (IOCs) include: - IP: 109.250.111[.]155 (Clickfix Delivery) - FQDN: namoet[.]de (Clickfix / C2 Server) - Port: 4444 (TCP Reverse Shell Listener) - URL: hxxp[:]//namoet[.]de:80/x (PowerShell Payload) - Registry (HKCU): SOFTWAREMicrosoftWindowsCurrentVersionRunOncewindows (Persistence on Boot) - Registry (HKCU): SOFTWAREMicrosoftWindows NTCurrentVersionWindowswin (Holds Obfuscated Command)

Why cybersecurity awareness and insider risk management are essential for SMBs

Small and medium-sized businesses (SMBs) are increasingly exposed to cyber threats, with human error being the leading cause of data breaches. Employees may click on malicious links, use weak passwords, or fall for phishing scams, highlighting the need for ongoing cybersecurity awareness training and insider risk management. Comprehensive training programs can help employees identify and mitigate threats, while modern cybersecurity platforms offer monitoring for exposed credentials on the dark web and provide real-time alerts for compromised information. These platforms also feature automated reporting, allowing business owners to track training completion and identify areas of risk. Educated and supported employees can become a strong defense against cyber threats, making investment in human-focused cybersecurity tools essential for SMBs to protect their reputation and financial health.

Hackers are sneaking malware into your browser using Google’s link, and antivirus software can’t stop it

A new browser-based malware campaign exploits trusted domains like Google.com to bypass traditional antivirus defenses. The malware operates through an e-commerce site using a manipulated Google OAuth logout URL, which executes an obfuscated JavaScript payload. This script activates silently during checkout or when the browser appears automated, opening a WebSocket connection to a malicious server. Payloads are dynamically executed using JavaScript, enhancing the threat's effectiveness. The attack evades detection by many antivirus programs due to its obfuscation and conditional activation. DNS filters and firewall rules offer limited protection since the initial request goes to a legitimate domain. Advanced users may use content inspection proxies or behavioral analysis tools to detect anomalies, but average users remain vulnerable. Recommendations to mitigate risks include limiting third-party scripts and maintaining separate browser sessions for financial transactions.

It’s time to stop believing these lies about antivirus software

The proliferation of social media misinformation, deep fakes, and sophisticated phishing attacks has made online safety challenging. Many individuals hold outdated beliefs about cybersecurity, such as the myth that Macs are immune to viruses and that caution alone can replace antivirus software. Regardless of the operating system, using a robust antivirus program is recommended, as built-in security features are not foolproof. Third-party antivirus software can provide additional functionalities like parental controls and VPN services, but they are not a complete safety net. Users must remain vigilant and practice good cybersecurity hygiene, including regular scans, strong passwords, and recognizing phishing attempts. Modern antivirus programs have become more user-friendly and less resource-intensive. Some malware can operate stealthily, making detection difficult, which emphasizes the need for regular scans and monitoring personal accounts for unusual activity. Antivirus protection should extend to mobile devices as well, as they are also vulnerable to cyber threats. Users should check if their antivirus program covers mobile devices and familiarize themselves with security settings on their smartphones.

Microsoft Data Loss Prevention (DLP): Tips to Protect Your Business Following the Latest Outage

Microsoft attributed a recent global outage affecting various digital infrastructures to a "CrowdStrike update," which disrupted multiple applications including OneDrive, OneNote, Outlook, PowerBI, Microsoft Teams, and others. Users experienced issues such as synchronization failures and access difficulties. The incident highlights vulnerabilities in supply chains that organizations rely on for managing sensitive data, which can be targeted by cyber threats. Data Loss Prevention (DLP) is a feature within Microsoft Purview designed to protect sensitive information from unauthorized disclosure. DLP policies can monitor user activity and take protective actions like alerting users about inappropriate sharing, blocking sharing attempts, or relocating data to secure locations. DLP can be applied across various platforms, including Office 365 applications and Windows endpoints. The DLP lifecycle includes planning and deployment phases, where organizations assess data to be monitored and ensure policies do not disrupt workflows. Monitoring and reporting tools provide insights into policy matches and incidents, helping organizations refine their DLP efforts. However, DLP has limitations, including false positives, user resistance, and challenges in detecting data leakages through new communication channels.
