Pre-OS Boot Anomaly & Malware Diagnostic Tool

The user describes a highly suspicious message appearing on a black screen during the PC's startup process, suggesting a potential malware infection, adware, or a compromised system. This is a critical and complex issue, as the operating system may not be fully functional, making standard antivirus scans difficult. A niche SaaS opportunity lies in a specialized tool for diagnosing and remediating these 'pre-OS' or 'boot-time' anomalies.

Product Form: This could be a web application that helps users identify known suspicious boot messages/behaviors and then guides them through creating a bootable USB diagnostic environment (e.g., based on a lightweight Linux distribution or Windows PE). This bootable environment would contain tools for scanning the main OS drive for rootkits, malware, system file integrity checks, or providing access to recovery options, all before the main Windows OS loads. It could also provide step-by-step instructions for booting into safe mode or using built-in Windows recovery tools when applicable. The SaaS component would include regular updates to the threat database and diagnostic workflows.

Expected Benefits: This service would provide a crucial first line of defense against boot-level malware and system corruption, which often bypass standard antivirus software. It would help users recover their systems without resorting to a full OS reinstall, saving significant data and setup time. The revenue model could be a subscription for regular updates and premium features, or a per-incident support model for more complex cases, targeting concerned individual users, small businesses, and IT support professionals.
