What is folding?
Boas ppl. tenho um problema. o meu processador está constantemente com um funcionamento a 100%. ou por vezes está 10 segundos a 100%, volta 10 segundos ao normal, e dps volta a 100%. isto constantemente.

reparei no gestor de tarefas, o ficheiro isass.exe por vezes ocupa de 60 a 90 do CPU. por vezes, o iexplorer.exe, apesar de n ter aberto, está a executar e a ocupar pelos 50 do cpu.

ja pesquisei sobre o worm que usa o isass.exe para atacar o pc, mas seundo dizem so ataca quem nao tem service pack2, e eu tenho.

Agradeço se alguem me pode ajudar.

cumps
 
Última edição:

Não deverias ter o processo Iexplorer.exe a correr se não o abres, algo está a abrir por ti, poem o log do hijackthis.de.
 
Ca esta o log:

eu tenho exactamente o mesmo problema e ele chama-se uTorrent. não sei porque mas de umas semanas para cá ele começou a encravar esses tais 10 segundo e fiz todos os scans inclusive ao disco a ver se havia algum erro. até o 3dmark corri a ver se podia ser da gráfica mas o problema resolveu-se qdo desliguei o utorrent (que abre cada vez que ligo o windows).
 
no site, quando meto o log e faço analyze, dps aparece algumas linhas com 'X'. como faço pa apagar isso? n percebi. :S
 
o que aparece é o que está abaixo. e isso nao da para fazer fix no hijackthis.


C:\WINDOWS\system32\drivers\taskmgr.exe This entry is not running from the System32 folder, so it is probably nasty.
This process is not running from the System32 folder as it is supposed to be.
 
penso k o ficheiro se chama lsass.exe não é??
se for pode ser um virus letal. já tive isso e sempre que ligava a net vinha uma caixa a dizer que tinhas 60seg para desligar o PC sem retorno algum...
 
mas ele nunca me reenicia o pc. mas tenho o pc smp a 100%. ou intervalos do tipo __/---\__/--\__/---\__/--\__/---\__/--\__/---\__/--\__. smp aos altos e baixos. ja instalei difrentes anti spywares e mesmo assim n resolvo isto. nao queria formatar. :S
