Removendo o vírus NATServ.exe
Olá!
Depois de instalar uma atualização do java, ou pelo menos que dizia ser atualização do java, meu gerenciador de tarefas começou, ao abrir ,fechar após 3 segundos. Rodei o Hijackthis e me deu o seguinte retorno:

Ao tentar executar o combofix para remover o possível trojan descobri que ele não funciona com windows 8.1. A opção que usei foi o Malwarebytes Anti-Malware. Porém antes dele terminar a execução, ao acessar o site do Banco do Brasil, o meu antivírus detectou o tal trojan. Foi identificado como NATServ.exe. Depois de o antivírus remover para quarentena o tal NATServ e acabar de executar o Malwarebytes Anti-Malware o gerenciador de tarefas voltou a abrir normal e no novo log do HijackThis não faz mais referência ao tal NATServ. Não achei nada sobre esse vírus na internet. Alguém sabe me dizer o que seria esse NATServ?
