Deixei meu notebook durante uma madrugada sincronizando meu Google Drive. Pela manhã descobri que foram instalados 2 programas (AVAST e BYTE FENCE). Como foi possível isso sem minha autorização? Notebook DELL Windows 10. Segurança Trend Micro Internet
Hi @cpatriciof, welcome to Trend Micro Community and we are sorry to inform you that we provide English service only in our Community currently.
For your issue, since Avast! and ByteFence are not a malicious program, Trend Micro Security will not block it. They are typically bundled with other freeware and installed as an option most people do not uncheck during installation.
For your safety, we suggest performing a Full Scan to make sure your computer is not infected. We have a help doc which describes how to performing a full scan: Running a scan using Trend Micro Security software - refer to"Performing Quick or Full Scan"
Also, please make sure if your User Account Control (UAC) is turned on. Here's a related Microsoft support page for your reference: Protect my PC from viruses - refer to "Turn User Account Control on or off"
Thank you and please let us know if you have more questions!
