Sounds like the MEDFOS trojan. Have you done virus scans independent of your real-time antivirus?

It definitely has to be malware. I have no doubt in my mind.

Hi Jonak,

One important information, that we didn't say so far, we are running windows 7 64 bit

@CoachellaMVCD,
I suggest that you spend a little more time on that system and run some other scans. "ComboFix" is one of the very best tools available, but it can't hurt to fire off a couple more weapons.

For Hijacking/re-directs, you might want to start with TDSSKILLER found here:
http://support.kaspersky.com/downloads/utils/tdsskiller.zip

* Download the file TDSSKiller.zip and extract it into a folder on the infected (or potentially infected) PC.
* Execute the file TDSSKiller.exe.
* Wait for the scan and disinfection process to be over. You do not have to reboot the PC after the disinfection is over.

If the tool finds a hidden service it will prompt you to type "delete", you can also just hit "Enter" without typing in and the scan will continue...
Please post the log to be analyzed.

You can also try FixTDSS.exe from Symantec:
http://www.symantec.com/content/en/us/global/removal_tool/threat_writeups/FixTDSS.exe

There are several EE Articles that cover all of the basics of proper malware removal and I encourage to to familiarize yourself with the steps you need to take.
