Title: Ameaça detectada, quando navego pelo Chrome
Post by: msilvia on October 24, 2011, 11:20:08 PM

Quando utilizo o Chrome para navegar, toda hora aparece o aviso: Uma Ameaça Detectada. E o Avast bloqueia o acesso à pagina.
Isso está acontecendo em sites como globo.com, banco do brasil, entre outros.
Mas quando uso o internet explorer para navegar não apresenta nenhum problema.

Já passei o antivirus, em todo o sistema e ele não encontra nenhum arquivo infectado.

Desinstalei o Chrome e instalei de novo e continuou dando o mesmo problema.

O que fazer?

Você consegue me seguir em inglês?

1. Clean your temporary files.
2. Schedule a boot time scanning with avast with archive scanning turned on. If avast does not detect it, you can try DrWeb CureIT! (http://www.freedrweb.com/cureit/) instead.
3. Use Comodo Cleaning Essentials (CCE) (http://www.comodo.com/business-security/network-protection/cleaning_essentials.php), or MBAM (http://malwarebytes.org/mbam.php), or SUPERantispyware (http://www.superantispyware.com) to scan for spywares and trojans. If any infection is detected, it is better and safer to send the infected file(s) to quarantine (Chest), rather than simply deleting them.
4. Test your machine with anti-rootkit applications (http://www.antirootkit.com/software/index.htm). I suggest avast! antirootkit (http://files.avast.com/files/beta/aswar.exe) or Trend Micro RootkitBuster (http://www.trendmicro.com/download/rbuster.asp).
5. Read these instructions (http://forum.avast.com/index.php?topic=53253.msg451454#msg451454) and provide more info with the logs generated. But, please, do NOT post there, open a NEW thread for your specific problem and help us to help you.
6. Clean your Hosts file (replacing it) with HostsMan (http://www.abelhadigital.com) tool.
7. Disable System Restore and then reenable it again.
8. Immunize your system with SpywareBlaster (http://www.javacoolsoftware.com/spywareblaster.html).
9. Check if you have insecure applications with Secunia Software Inspector (http://secunia.com/software_inspector/).
