To clarify a slight naming distinction, there is no official tool called “NVT Windows Securer.” Instead, you are likely thinking of security applications developed by NoVirusThanks (NVT), an Italian cybersecurity firm. They specialize in endpoint hardening tools designed to protect your PC by shrinking its attack surface.
The primary tools NVT provides to secure a Windows PC are OSArmor and SysHardener. They act as defensive blockades alongside your primary antivirus (like Microsoft Defender).
Here is how you can use these core NVT tools to secure your system: 1. Stop Malicious Actions with NVT OSArmor
OSArmor is a “set-and-forget” application behavior monitor. It does not scan files like a traditional antivirus; instead, it prevents common tactics that malware uses to hijack a PC.
Block Child Processes: It stops programs like Microsoft Word or Adobe Reader from spawning command lines or PowerShell instances. This blocks malicious macros from downloading payloads.
Stop Double Extensions: It blocks files named like invoice.pdf.exe which trick users into executing code.
Protect Shadow Copies: It blocks system utilities (like vssadmin.exe) from being abused by ransomware trying to delete your system backups. 2. Lock Down Vulnerable Settings with NVT SysHardener
SysHardener is a proactive hardening utility. It closes common entry points built into the operating system by applying strict security policies.
Disable Scripting Frameworks: It allows you to toggle off Windows Script Host (WSH), VBScript, and JavaScript executed outside of a browser, rendering typical script-based malware useless.
Restrict Unused File Associations: It can unregister risky file extensions that are rarely needed by typical users, such as .vbs, .js, .jse, .pif, .iso, or .img files.
Harden Built-in Apps: It tightens privacy and security settings across basic network protocols and standard system components. How to Implement NVT Protection Properly
Run Alongside Microsoft Defender: NVT software is intentionally lightweight and built to supplement Windows Security rather than replace it. Keep your real-time antivirus active.
Start with Default Profiles: When launching OSArmor or SysHardener, stick to the recommended defaults. Tightening settings too far right away can block legitimate apps or remote work tools.
Check the Logs for Blocked Apps: Because these tools enforce zero-trust rules, you may occasionally experience a false positive where a safe app update gets blocked. You can easily whitelist trusted file hashes or parent folders via the built-in configurator.
Are you experiencing a specific type of malware threat, or are you looking to harden a PC for a particular user environment (like a remote work computer or a gaming setup)? Let me know so I can tailor the recommended configurations. Stay protected with the Windows Security app
