This issue affects Avast Antivirus, AVG Antivirus, Norton Antivirus, Avast One, and Avast Business Antivirus on Windows, macOS, and Linux for virus definition builds before VPS 25020100.
The affected scanning logic is delivered through a shared Gen Digital virus definition update stream.

Mitigation flows through this update channel; installations at or above the listed build are not vulnerable regardless of which product consumes the stream.
