Então, meu SvcHost está, de repente, tirando 100% da minha CPU, e eu gostaria de descobrir qual serviço é responsável por isso. Existe alguma maneira de diferenciar a carga sendo gerada pelos vários serviços em execução em um único SvcHost?
Eu executei uma verificação de vírus e ela ficou limpa minha ferramenta é antiga e está desatualizada, por isso não encontrou nada.
Eu tentei percorrer os serviços, parando-os um por um, mas não consegui encontrar o culpado (note que alguns serviços também foram reiniciados automaticamente e eu não queria desativá-los).
Atualização: usei o Process Explorer ontem à noite, mas há havia muitos serviços, alguns dos quais não podiam ser interrompidos, no SvcHost ofensivo. Hoje verifiquei novamente a sugestão de heavyd e tive sorte porque apenas dois serviços estão no SvcHost ofensivo hoje.
DcomLaunch - Iniciador de processos do servidor DCOM
TermService - Serviços de terminal
Nenhum dos quais é interrompível. Estou atualizado com as atualizações do Windows. Indo para executar outra verificação de vírus para o inferno, embora nada tenha aparecido na noite passada . Talvez seja hora de começar de novo (essa instalação é de algum dia de 2004).
Atualização: Definitivamente, um vírus. Após a última reinicialização, o uso da CPU caiu, mas recebi algumas mensagens estranhas de "Software de Segurança Instalada" na inicialização, processos estranhamente nomeados em execução (por exemplo, 555573478785.exe
) e chaves suspeitas adicionadas a HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
que não estavam lá na noite passada .
O Symantec AntiVirus Corporate 8.1.0.825 apresentou alguns avisos, mas parece que não está pegando tudo: - (
