Hi,

I have bad news I'm afraid.

One or more of the identified infections is a Backdoor Trojan.

OK since we are dealing with the aforementioned infection(s) I would be providing your good self with a disservice if I did not make you aware of the ramifications below:

This allows hackers to remotely control your computer, steal critical system information and Download and Execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Although an attempt could be made to clean this machine, it could never be considered to be truly clean, secure, or trustworthy. We could not say definitively that unknown and unseen malware will have been removed, nor will your system be restored to its pre-infection state. We cannot remedy unknown changes the malware may likely have made in order to allow itself access, nor can we repair the damage it may possibly have caused to vital system files. Additionally, it is quite possible that changes made to the system by the malware may impact negatively on your computer during the removal process. In short, your system may never regain its former stability or its full functionality without a reformat. Therefore, your best and safest course of action is a reformat and reinstallation of the Windows operating system, and that is the course we strongly recommend.

Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

When Should I Format, How Should I Reinstall

I can attempt to clean this machine but I can't guarantee that it will be at all secure afterwords.

Should you have any questions, please feel free to ask.

Please let myself know what you have decided to do in your next post.

thank you so much for your reply. I decided to make a format of the disk so i can be totally safe:)
thank you

Hi.

thank you so much for your reply. I decided to make a format of the disk so i can be totally safe:)
thank you

Marco

OK and you're welcome!

Below is some advice about what to install/safety advice after the format and the reinstallation of the Windows operating system.

Reformat and Reinstallation Advice:

This is a excellent resource I recommend reading:-

How to prevent Malware.

Next:

• Use an Anti Virus Software - It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.
  Here are some free Anti Virus programs which I recommend to use:
  
  • Antivir PersonalEditionClassic
    
    • Free anti-virus software for Windows.
    • Detects and removes more than 50,000 viruses. Free support.
  • avast! 4 Home Edition
    
    • Anti-virus program for Windows.
      
    • The home edition is freeware for noncommercial users.
  • Update your Anti Virus Software - It is imperative that you update your Anti virus software at least once a week (Even more if you wish). If you do not update your anti virus software then it will not be able to catch any of the new variants that may come out.
  • Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is susceptible to being hacked and taken over. Simply using a Firewall in its default configuration can lower your risk greatly.
    Here are some free Firewalls which I recommend to use:
    (Use only one, and disable your Windows Firewall)
    
    • Sunbelt Kerio
    • Outpost
    • Jetico Personal Firewall
  Note: Only ever have installed/use one Anti-Virus application and Software Firewall. Otherwise a system conflict will occur and this also lessens overall online protection!
  
• Keep your system updated- Microsoft releases patches for Windows and other products regularly:
  
  • I advise you visit: http://update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en-us
  • Install the Active X
  • Once installed it will advise set Auto-Updates if not set and you then you will be able to manually check for updates also via:
  • Start >> All Programs >> Microsoft Updates
• Make your Internet Explorer more secure - This can be done by following these simple instructions:
  
  • From within Internet Explorer click on the Tools menu and then click on Options.
  • Click once on the Security tab
  • Click once on the Internet icon so it becomes highlighted.
  • Click once on the Custom Level button.
    
    • Change the Download signed ActiveX controls to Prompt
    • Change the Download unsigned ActiveX controls to Disable
    • Change the Initialise and script ActiveX controls not marked as safe to Disable
    • Change the Installation of desktop items to Prompt
    • Change the Launching programs and files in an IFRAME to Prompt
    • Change the Navigate sub-frames across different domains to Prompt
    • When all these settings have been made, click on the OK button.
    • If it prompts you as to whether or not you want to save the settings, press the Yes button.
  • Next press the Apply button and then the OK to exit the Internet Properties page.
• Malwarebytes' Anti-Malware - Download it from here
  The tutorial on how to use MBAM is located here
• Install WinPatrol - Download it from here
  You can find information about how WinPatrol works here
• Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.
  Download it from here
  The tutorial on how to use Spyware Blaster is located here
• Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.

Importance of Regular System Maintenance:

I advice you read both of the below listed topics as this will go a long way to keeping your Computer performing well after the format and the reinstallation of the Windows operating system.

Help! My computer is slow!

Also so is this:

What to do if your Computer is running slowly

Follow the above and the potential for your computer becoming infected again will reduce dramatically. Any questions feel free to ask OK!
