Hi elianetelles,
Follow the relevant advice here, but scan with avast! instead of Trend Micro:
Solution:
Identifying the Malware Program
To remove this malware, first identify the malware program.
- Scan your system with your Trend Micro antivirus avast! product.
- NOTE all files detected as TROJ_ZOMBIE.12 Win32:Zombie-B.
[Additional step: upload the file to VirusTotal to confirm it is indeed TROJ_ZOMBIE.12/Win32:Zombie-B:

You may need to extract the file from the chest and temporarily disable avast! in order to send the file to VirusTotal. If the file is identified as the above virus, proceed as below. If only avast! identifies it as malware, submit the file to avast! from the virus chest.]
Trend Micro customers need to download the latest pattern file before scanning their system. Other users can use Housecall, Trend Micro’s online virus scanner.
Terminating the Malware Program
This procedure terminates the running malware process. You will need the name(s) of the file(s) detected earlier.
-
Open Windows Task Manager.
» On Windows 95, 98, and ME, press
CTRL+ALT+DELETE
» On Windows NT, 2000, and XP, press
-
CTRL+SHIFT+ESC, then click the Processes tab. In the list of running programs*, locate the malware file(s) detected earlier.

-
To check if the malware process has been terminated, close Task Manager, and then open it again.
-
Close Task Manager.
*NOTE: On systems running Windows 95, 98, and ME, Windows Task Manager may not show certain processes. You can use a third party process viewer such as Process Explorer to terminate the malware process. Otherwise, continue with the next procedure, noting additional instructions.
