[Resolvido] Pc lento

Olá,

Hoje eu passei norton antivirus nu meu pc, e qdo ele passou por duas pastas, que continham arquivos baixados da internet, ele ficou muito lento. Depois que verificou essas duas pastas, ele voltou ao normal. Já pesquisei de tudo, mas naum encontrei problema algum, e o norton naum detectou nada nessas pastas. Suspeito que seja algum vírus que o meu programa naum tenha detectado. Esses "agarramentos" que ocorrem durante a verificação dessas duas pastas começaram a acontecer pela primeira vez, isso nunca tinha acontecido.
