Executive Summary

\nDriverBooster (developed by IObit) is widely classified by enterprise security vendors as a Potentially Unwanted Program (PUP) or \"Rogue Software.\" While marketed as a legitimate utility to automatically update outdated Windows drivers, its aggressive marketing tactics, intrusive behavior, and tendency to install incorrect or unstable drivers pose significant operational risks to corporate environments, leading to system instability and increased IT support overhead.\n\n

Infection Vector and Technical Capabilities

\nDriverBooster is typically installed intentionally by end-users seeking to \"optimize\" their PCs, or it is bundled silently alongside other freeware downloads from third-party aggregators.\n\nUpon installation, it exhibits several behaviors characteristic of PUPs:\n\n\n

Threat Assessment

\nWhile DriverBooster is not malicious in the sense of stealing data or encrypting files, it is highly detrimental to enterprise stability. The unauthorized modification of low-level system drivers bypasses IT change management controls and is a leading cause of localized endpoint outages.\n\n
