Welcome to TechSpot, aribas. Looks like the language of the day is not English! I'll do what I can. There will be problems though:
I see this in the HijackThis log:
Command: C:\Arquivos de programas\gbplugin.exe
Description: Added by the TSPY_BANKER.ZEG spyware.
It causes incorrect identification of the "gbiehuni.dll" file - a component of G-Buster Browser Defense (see
www.gasinf.com.br ) used by users of some Internet Banking Services in Brazil. It is a Trojan named PWS-Bamber.dll
This Trojan targets several banks, so I advise you to immediately change all of your passwords and monitor any online financial transactions.
Please download ComboFix
HERE:
- With ComboFix, at the download window, please rename it to Combo-Fix(.exe) before downloading it.
Save the Combofix download to your desktop.
- Please disable all security programs, such as antiviruses, antispywares, and firewalls. Also disable your internet connection.
- Run Combo-Fix.exe and follow the prompts.
(Understand that things like your system clock changing and your desktop disappearing might happen. Do not worry, because all will be restored later.)
- Wait for the scan to be completed.
- If it requires a reboot, please do it.
• After the scan has completed entirely, please post the log here. The log will be located at C:\ComboFix(.txt)
Notes:
1.Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. ComboFix may reset a number of Internet Explorer's settings, including making I-E the default browser.
3. Combofix prevents autorun of ALL CD, floppy and USB devices to assist with malware removal & increase security. If this is an issue or makes it difficult for you -- please tell your helper.
4. CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.
Follow with this online scan.
