Your Android App Needs Scanning – Best Android App Vulnerability Scanner in 2026

The past year saw a 45% increase in new vulnerabilities targeting Android. By the end of 2024, there are projected to be 2.87 million apps on Google Play, with 66% of American employees using personal smartphones for work. Mobile applications are responsible for 70% of digital interactions, and vulnerabilities in these apps contributed to approximately 40% of data breaches involving personal data in 2023. Effective Android App Vulnerability Scanners analyze app security by identifying insecure local storage, hardcoded credentials, weak cryptography, insecure network configurations, broken authentication flows, and misconfigured components. AI-powered scanners, like AutoSecT, can autonomously generate new scanning protocols quickly, detect zero-day vulnerabilities, automate penetration testing, and operate with near-zero false positives.

Trusted Antivirus Protection for PCs

Your PC requires robust antivirus protection due to its diverse usage, and Windows 11 offers built-in protections that operate seamlessly. Antivirus software, such as Microsoft Defender in Windows 11, protects against threats like viruses, malware, phishing websites, and suspicious email attachments. However, it cannot fully defend against social engineering scams, new ransomware, zero-day vulnerabilities, or risky online behaviors. Microsoft Defender provides automatic threat scanning, works with the Windows firewall, utilizes cloud intelligence, alerts users to unsafe content, and offers ransomware protection. To enhance security, users should keep software updated, use strong passwords, secure their Wi-Fi, enable firewalls, and back up files regularly.

Hackers Use Fake Windows BSOD To Spread Malware

Security researchers have identified a social engineering campaign that mimics the Windows Blue Screen of Death (BSOD) to deceive users into installing a remote access Trojan (RAT). The campaign, named PHALT#BLYX, begins with phishing emails that appear to be legitimate cancellation notices from travel websites, leading victims to a fake login page and an interactive CAPTCHA. This culminates in a full-screen imitation of the BSOD, prompting users to follow instructions that ultimately allow attackers to gain control of their computers. The attackers use a “ClickFix” process that involves executing commands through native Windows tools like PowerShell and MSBuild, making detection more challenging. The malware delivered is an obfuscated version of DCRat, which provides attackers with remote control capabilities, keylogging, and the ability to download additional malware. The campaign primarily targets hotels and hospitality businesses in Europe, exploiting the urgency of front-desk staff to respond to apparent technical issues. Indicators of a fake BSOD include the ability to interact with the screen, requests to execute commands via Windows tools, and the presence of CAPTCHA prompts. Organizations are advised to train employees, implement application control, enhance email and web defenses, and prepare for incident response to mitigate risks associated with such attacks.

Ditching Antivirus: Why One Tech Writer’s PC Got Safer Without It

A writer from MakeUseOf uninstalled all third-party antivirus programs from his Windows PC and found that the system performed better and appeared more secure with Microsoft’s built-in Windows Defender. The experiment highlighted Defender's effectiveness, showing fewer false positives, improved performance, and no noticeable decline in protection. Independent tests ranked Defender highly in real-world protection, and it achieved perfect scores in recent AV-TEST evaluations. The removal of third-party antivirus software led to a significant decrease in CPU and RAM usage, with idle consumption dropping from 15-20% to under 5%. Despite 121 million Americans still using third-party tools, there is growing consideration for Defender due to its free and efficient nature. While Defender excels in many areas, experts caution that it may not fully protect against zero-day vulnerabilities, and layered defenses are still recommended. The antivirus market may face disruption as integrated protection becomes more common, and user feedback indicates a preference for free alternatives that match or exceed the performance of paid solutions.

2025 Antivirus Trends, Statistics, and Market Report

In 2025, approximately 66 percent of U.S. adults use antivirus software, with 25 percent using it on both business and personal devices and 41 percent using it only on personal devices. This leaves 34 percent of Americans without antivirus protection. About 169 million Americans actively employ antivirus software, but there is a 20 percentage point gap between the 85 percent who believe antivirus is essential and the 66 percent who use it. Protection levels vary by device type: 63 percent of personal computer owners use real-time antivirus software, 25 percent of smartphone owners do, and only 22 percent of tablet owners utilize antivirus protection. Among personal computer users, 69 percent of Windows users have antivirus software compared to 37 percent of macOS users. Antivirus adoption increases with age, with 73 percent of users aged 60 and older using antivirus on PCs, compared to 51 percent of those aged 18-29. The antivirus market has shifted toward free solutions, with free antivirus usage rising to 61 percent in 2025 from 52 percent in 2024, while paid subscription usage decreased from 44 percent to 36 percent. Free antivirus tools have improved significantly, but they often lack advanced features necessary for high-risk users.

When the Patches Stop: Protecting Your (Windows 10) Environment with CDR

Microsoft has ceased providing free security updates for Windows 10 as of mid-October 2025, marking the end of support for the operating system. Organizations can purchase Extended Security Updates (ESUs) to extend support temporarily, but these do not protect against zero-day vulnerabilities. Transitioning to Windows 11 presents challenges, including hardware incompatibility and the need for extensive planning and validation in regulated industries like healthcare and finance. Many businesses rely on Windows 10 systems that are integral to their operations and cannot easily be replaced. Cybercriminals exploit unpatched systems, with approximately 70% of successful breaches stemming from zero-day attacks. Traditional defenses are ineffective against undisclosed vulnerabilities, and human behavior remains a significant risk factor. Votiro offers a proactive solution through Content Disarm and Reconstruction (CDR), which sanitizes files in real-time to eliminate malware before it reaches unpatched systems, providing a protective barrier for organizations still using Windows 10.
