Han mandado al técnico o es un fraude ?
Where did you see this report about Avast sending a technician?
Was it an email? If true, check the source of the email. It is likely not from Avast and should be considered a scam as Avast would not do this.
Can you post a screenshot.
Do not click on links in the email or call any phone numbers if given.
Note. I’m not an Avast Team member, just another user.
