[Resolvido!] Possível vírus - Análise de Log

Leonardofr · Junho 1, 2009

Boa tarde!

Acredito que meu computador esteja infectado pois ao acessar sites que necessita de javascript, ele carrega o banner (ex. yieldmanager) e fica só nisso, não carrega o conteúdo da página. Um exemplo disso acontece no gamegol.com.br, onde após logar, fica apenas o banner de propaganda e o conteúdo fica a carregar.

Segue abaixo LOG do HijackThis:
