Avast: report virus - how it works

If you find a virus or other malware that Avast does not recognize, you can report the file to the manufacturer. The same also works - albeit somewhat differently - for infected websites. In this practical tip, we will show you how to proceed in both cases.

Report infected websites to Avast

You must also send Avast an email for infected websites, although the email address is different:

2. In the text field of the email, first state the complete URLs of the infected websites.
3. You can then briefly describe what the harmful behavior of the website looks like that you have noticed.
