Hello, this is usually a malware. I moved this to the Am I Infected forum.

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Troubleshoot Malwarebytes' Anti-Malware




Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.5.22.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.


If TDSSKiller does not run, try renaming it. To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to these[/color] instructions. [color=green]In some cases it may be necessary to redownload TDSSKiller and randomly rename it before downloading and saving to the computer.

Well, depends with how much your free space on your C drive decreases. It might simply be temporary files being constantly added/removed (due to web browser activity while you are surfing the net for example) that would decrease the free space in the matter of tens of MB. if the rate is quick and seems uncontrolled though, as advised - might be some kind of malware.
que fuerte!

Restart the computer again and verify that MBAM is in the task tray and run a Quick Scan and post that log.

It would appear you are clean for now. Looks like the Angry Birds was a Cracked version and infected the machine.

Angry Birds Cracked Final Complete Pack

IMPORTANT NOTE: The practice of using cracking tools, keygens, warez or any pirated software is not only considered illegal activity but it is a serious security risk.

Cracking applications are used for illegally breaking (cracking) various copy-protection and registration techniques used in commercial software. These programs may be distributed via Web sites, Usenet, and P2P networks.

trendmicro.com/vinfo

...warez and crack web pages are being used by cybercriminals as download sites for malware related to VIRUT and VIRUX. Searches for serial numbers, cracks, and even antivirus products like Trend Micro yield malcodes that come in the form of executables or self-extracting files...quick links in these sites also lead to malicious files. Ads and banners are also infection vectors...

Keygen and Crack Sites Distribute VIRUX and FakeAV

...warez/piracy sites ranked the highest in downloading spyware...just opening the web page usually sets off an exploit, never mind actually downloading anything. And by the time the malware is finished downloading, often the machine is trashed and rendered useless.

University of Washington spyware study

...One of the most aggressive and intrusive of all bad websites on the Internet are serial, warez, software cracking type sites...they sneak malware onto your system...Where do trojan viruses originate? One of the biggest malware distributors on the Internet are serial/warez/code cracking sites.

Bad Web Sites: Malware

When you use these kind of programs, be forewarned that some of the worst types of malware infections can be contracted and spread by visiting crack, keygen, warez and other pirated software sites. In many cases, those sites are infested with a smörgåsbord of malware and an increasing source of system infection. Those who attempt to get software for free can end up with a computer system so badly damaged that recovery is not possible and it cannot be repaired. When that happens there is nothing you can do besides reformatting and reinstalling the OS.

Before we can continue, I need you to remove all cracks and keygens immediately to reduce the risk of infection/reinfection. If not, then we are just wasting time trying to clean your system. Further, other tools used during the disinfection process may detect crack and keygens so we need to ensure they have been removed.

Using these types of programs or the websites you visited to get them is almost a guaranteed way to get yourself infected!!

Ok, check for anything that may be left.

Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.
