Try these steps before calling. They resolve the majority of common ESET issues.

1

Enable ESET's UEFI Scanner

ESET is one of the few antivirus programs that scans your PC's firmware (UEFI/BIOS) for rare but serious rootkit infections. Enable it in Advanced Setup → Detection Engine → UEFI Scanner.

2

Use Password Audit feature

ESET Smart Security Premium includes a Password Manager with a Password Audit feature that identifies weak, duplicate, and breached passwords across your saved credentials.

3

Activate Gamer Mode manually

When gaming or watching movies, enable ESET Gamer Mode manually from the taskbar icon to suppress notifications and scheduled scans. Don't leave it on permanently — it reduces protection.
