[Arquivado] Infectado por spyware ou malware

Jmax · Julho 31, 2006

Gostaria de receber ajuda para limpar meu pc pois toda vez que estou com o navegador aberto fica aparecendo um popup com título "Advertisment - NSIS

jgarcia · Julho 31, 2006

Opa Jmax,

Faça o seguinte:

Baixe o HijackThis versão 1.99.1.

Depois > Iniciar > Meu Computador > 02 cliques no C > Coloca o HijackThis no C (extraindo do zip --> para uma pasta própria tipo c:/Hijack).

Execute o Hijack a partir do C, fechando os demais programas (deixando somente a área de trabalho).

Clique em Do a system scan and save a logfile, mas não marque nada, apenas poste o log gerado aqui neste mesmo tópico.

Abraços.

Existe um programa no meu computador que está instalado como NSIS Media Extension, removo ele e também as referências no regedit enquanto eu não reiniciar a máquina está tudo bem, mais quando reinicio a máquina a praga volta a atuar. Segue abaixo meu log.

Opa Jmax,

Vamos lá.

Habilite o Windows para mostrar todos os arquivos (até ocultos).

É prudente que você faça a impressão deste documento ou salve-o em um lugar de fácil acesso, pois na próxima etapa entraremos em Modo de Seguro e a conexão à internet não será possível.

Reinicie o computador em Modo Seguro (após reiniciar aperte a tecla F8 até aparecer uma tela preta em DOS e escolha Modo Seguro).

Execute o HijackThis, clique em Do a system scan only e marque:

R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Local Page = C:\windows\system32\blank.htm
R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Local Page =

O16 - DPF: {2AF5BD25-90C5-4EEC-88C5-B44DC2905D8B} (DownloadManager Control) - http://dlmanager.akamaitools.com.edgesuite...vex-2.0.4.4.cab

Clique em Fix Checked.

Reinicie em Modo Normal.

Poste o novo log do HijackThis.

Aguardo retorno.

Um abraço.
