Malware resistente

[Luan Masson]

No dia 18/08 eu e meus amigos relatamos processos de host bem bizarros em nossos computadores, achamos que foi algum malware em ataque ao navegador Brave, pois ele primeiramente se mostrou nele e somente quem o tinha instalado no computador apareceu esses hosts esquisitos.

 

Primeiro contato: A primeira vez que o vírus se mostrou presente em meu computador foi quando eu tentei escrever alguma coisa direto na barra de pesquisa e o Brave me levava a uma página de redirecionamento, e nisso o Norton antivírus bloqueava essa página falando que podia ser maliciosa.

Eu sempre fui o mais careta nessa área entrei em choque e já comecei a tentar remover o malware, mas ao tentar remover o host de serviço em que ele atuava ele simplesmente criava outro, então fui tentar fazer o que todo desesperado faz, procurei em fóruns, baixei alguns aplicativos que pessoas falavam e rodei-os em meu computador.

 

Norton antivírus: O Norton nem mesmo detectou o vírus em meu computador.

SpyHunter 5: Tentei rodar o SpyHunter5 logo de primeira quando eu vi que ele literalmente rastreia tudo no computador, porém nada...

 

Kaspersky cloud free: Esse foi monstro, logo fiz a varredura completa e me deu a seguinte informação:

 

System Memory    Não processado    Não é possível desinfetar    MEM:Trojan.Win32.SEPEH.gen    Adiado    Arquivo        System Memory    Não processado    Trojan    Alto    Exatamente    DESKTOP-UKTUV62\luanm    Usuário ativo
Hoje, 18/08/2022 21:03:44    System Memory    Detectado    Objeto malicioso detectado    MEM:Trojan.Win32.SEPEH.gen    Análise especializada    Arquivo        System Memory    Detectado    Trojan    Alto    Exatamente    DESKTOP-UKTUV62\luanm    Usuário ativo.

visto isso pensei "Se tá na memória do sistema vou formatar né?".

 

Quem disse... Que estava inicialmente no Windows10 continuou  no Windows11.

Algumas fotos que tirei:

Hosts de serviços que acredito que sejam duplicatas criadas pelo vírus, eles mudam os números finais toda vez que o pc é reiniciado, um print foi tirado as 3:00AM e outro as 10:00AM.

Se você passou apenas para o windows 11 sem usar o pendrive bootável, ai ele continua mesmo, tente o malwarebytes, talvez ele pegue

Fiz com o pendrive bootavel, usei o cmd para dar clean em todos os meus discos rígidos.
