The signature feature: Click the green “Install drivers automatically” button. The software scans your hardware IDs, matches them to its local database, and installs everything in about 5–15 minutes. It even creates a System Restore point before starting.
Some antivirus programs flag any driver installer because drivers have deep system access. Also, the optional bundled offers (like Avast) trigger PUP warnings. Whitelist the folder if you are sure of the source.
