[Resolvido] &nbspRede caindo e computador congelando

Olá a todos

A alguns dias um computador menos importante da rede começou a congelar sozinho. Somente resetando para voltar.

Depois de alguns dias a rede começou a cair, fiquei uma hora buscando o problema, até que lembrei que havia isolado este computador e ele estava congelado, tinha esquecido de resetar. Quando resetei, a rede voltou instantaneamente.

Ficou claro que é vírus ou malware. Quando ela está fora da rede, nada acontece, tudo normal.

Preciso de ajuda para caçá-lo, uma vez que não posso formatar a máquina.
