Use Avast Assistant

Avast Assistant is designed to work in all languages but currently performs best in the following: English, French, German, Japanese, and Spanish.

These languages were chosen based on factors such as user demand, the availability of cybersecurity threat data, and the linguistic complexity involved in scam detection. Language support is continuously expanding, with future updates expected to include additional languages as the system learns and evolves.

It analyzes text messages, emails, links, and images to detect potential scams, phishing attempts, and other cybersecurity threats. Aside from identifying suspicious content, the assistant provides practical guidance to help users understand and appropriately respond to safety concerns.
