[Arquivado] Não consigo me livrar de um Malware

Rodolfus · Julho 11, 2007

O PC está lento e a todo momento uma janela com Winantivirus abre. Alguém pode ajudar?

O Spybot e o antivirus eliminam o problema, porém a cada "boot" o problema reaparece com nomes diferentes.

Ah, não consigo também restaurar o sistema. Socorro!

Como tenho visto que é de praxe, segue o log do HijackThis:

1 Baixe o BankerFix em:

http://p.download.uol.com.br/linhadefensiv...x/bankerfix.exe

2. Desative o seu anti-vírus temporariamente.

3. Dê um duplo-clique sobre o bankerfix.exe. Uma mensagem aparecerá avisando que o mesmo será baixado via internet. Clique em Ok -> Ok. Aperte Enter e aguarde o término do scan.

4. Terminado o scan, leia a mensagem na tela e aperte Enter novamente.

5. Habilite o seu anti-vírus.

6. Retorne com um novo log do HijackThis, juntamente com o relatorio.txt do BankerFix (ele estará em C:\LinhaDefensiva\).

7. Depois de postar a sua resposta você poderá deletar a pasta LinhaDefensiva contida no C.

OBS: você USA PROXY ?

Abraços.

Fiz tudo conforme solicitado.

Obs: O proxy eu utilizo somente quando vou me conectar a um servidor de um curso. Pode verificar que agora ele deve sumir.

Quanto ao BankerFix, apareceu uma tela informando que a execução foi concluída com êxito e que nenhum problema foi encontrado no computador. Segue abaixo...
