[Arquivado] &nbspTela de erro e computador reiniciando

Olá, meus caros!

Nos últimos dias, o meu computador tem dado, com uma frequencia razoável, uma tela azul de um erro fatal que faz com que o pc precise ser desligado para proteção dos dados.

Fui fazer uma análise com o HijackThis para postar aqui e durante a pesquisa a seguinte mensagem apareceu:

"For some reason your system denied write access to the Hosts file. If any hijacked domains are in this file, HijackThis may NOT be able to fix this.

If that happens, you need to edit the file yourself. To do this, click Start, Run and type:

notepad C:\Windows\System32\drivers\etc\hosts

and press Enter. Find the line(s) HijackThis reports and delete them. Save the file as 'hosts' (with quotes), and reboot.

For Vista: simply, exit HijackThis, right click on the HijackThis icon choose 'Run as administrator'."

Aqui está o resultado do log realizado:

Talvez o problema nem seja com vírus ou algo do tipo, mas como eu nunca fiz uma análise nessa máquina, achei importante fazer por precaução. :)
