What this infection does:

Advanced Defender is a rogue anti-spyware program from the same family as Personal Protector. This rogue is distributed through malware that will install the program onto your computer without your permission or knowledge. While being installed this program will also create fake and harmless malware files on your computer that will be detected by Advanced Defender when it scans your computer. The files it creates are:

c:\WINDOWS\certofsystem.exe
c:\WINDOWS\explorers.exe
c:\WINDOWS\microsoftdefend.dll
c:\WINDOWS\regp.exe
c:\WINDOWS\secureit.com
c:\WINDOWS\spoos.exe
c:\WINDOWS\system32\winscent.exe

Once installed, Advanced Defender will hide your desktop icons and then start scanning your computer for infections. When done it will list a variety of infections, including the fake ones above, but will not allow you to remove them until you first purchase the program. Many of the infections it states, though, are legitimate programs that if deleted would affect the proper operation of your computer. Therefore, please do not manually delete any of the files on your computer that it states are infections.

As a method to protect itself, Advanced Defender will terminate almost any executable that you run while stating that the file is an infection. It does this to stop legitimate anti-malware programs from removing it. When an executable is launched it will display a message that contains the following text:

Cmd.exe is infected with worm Lsas.Blaster.Keyloger. This worm is trying to send your credit card details using to connect to remote host.

Do not worry, though, your executables are not infected. This is just another fake alert of the program.

While the program is running you will also see fake security alerts stating that your computer is under attack or that malware has been detected that can steal your personal information. An example of one of these alerts is:

Attention! System detected a potential hazard on your computer that may infect executable files. Your private information and PC safety is at risk.
To get rid of unwanted spyware and keep your computer safe you need to update your Current security software.
Click Yes to download official intrusion detection system (IDS software)

Just like the scan results and fake infection messages, these security warnings are just another trick by Advanced Defender to make you think you are infected.

As you can see, Advanced Defender was created for one purpose; to scare you into thinking your computer has a security problem so that you will then purchase the program. It goes without saying that you should not purchase this program regardless of what it may state. If you have already purchased the program, then please contact your credit card company and dispute the charges. Finally, please use the guide below to remove this infection and any related malware for free.

Automated Removal Instructions for Advanced Defender using Malwarebytes' Anti-Malware:

1. Print out these instructions as we may need to close every window that is open later in the fix.
   
   
2. It is possible that the infection you are trying to remove will not allow you to download files on the infected computer. If this is the case, then you will need to download the files requested in this guide on another computer and then transfer them to the infected computer. You can transfer the files via a CD/DVD, external drive, or USB flash drive.
   
   
3. Before we can do anything we must first end the processes that belong to Advanced Defender so that it does not interfere with the cleaning procedure. To do this, download the following file to your Desktop.
   
   rkill.com Download Link
   
   
4. As this infection hides the Windows desktop, we need to open up a window that allows us to see the icons.
   
   If you are using Windows XP perform the following steps:

   Click on the Start button and then click on the Run menu item. When the Run box opens, type %UserProfile%\desktop in the Open: field and then press Enter on your keyboard.

   If you are in Windows Vista or Windows 7 perform the following steps.

   Click on the Start button and type %UserProfile%\desktop in the Search field at the bottom of the start menu. Then press Enter on your keyboard.

5. You should now see a window that shows all of your desktop icons, including the rkill.com program. Now double-click on the rkill.com in order to automatically attempt to stop any processes associated with Advanced Defender and other Rogue programs. Please be patient while the program looks for various malware programs and ends them. When it has finished, the black window will automatically close and you can continue with the next step. If you get a message that rkill is an infection, do not be concerned. This message is just a fake warning given by Advanced Defender when it terminates programs that may potentially remove it. If you run into these infections warnings that close Rkill, a trick is to leave the warning on the screen and then run Rkill again. By not closing the warning, this typically will allow you to bypass the malware trying to protect itself so that rkill can terminate Advanced Defender . So, please try running Rkill until the malware is no longer running. You will then be able to proceed with the rest of the guide. If you continue having problems running rkill.com, you can download iExplore.exe or eXplorer.exe, which are renamed copies of rkill.com, and try them instead.
   
   Do not reboot your computer after running rkill as the malware programs will start again.
   
   
6. Now you should download Malwarebytes' Anti-Malware, or MBAM, from the following location and save it to your desktop:
   
   Malwarebytes' Anti-Malware Download Link (Download page will open in a new window)
   
   


7. Once downloaded, close all programs and Windows on your computer, including this one.
   
   
8. Double-click on the icon on your desktop named mbam-setup.exe. This will start the installation of MBAM onto your computer.
   
   
9. When the installation begins, keep following the prompts in order to continue with the installation process. Do not make any changes to default settings and when the program has finished installing, make sure you leave both the Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware checked. Then click on the Finish button. If MalwareBytes' prompts you to reboot, please do not do so.
   
   
10. MBAM will now automatically start and you will see a message stating that you should update the program before performing a scan. As MBAM will automatically update itself after the install, you can press the OK button to close that box and you will now be at the main program as shown below.
    
    
    
    
    
    
    
11. On the Scanner tab, make sure the the Perform full scan option is selected and then click on the Scan button to start scanning your computer for Advanced Defender related files.
    
    
12. MBAM will now start scanning your computer for malware. This process can take quite a while, so we suggest you go and do something else and periodically check on the status of the scan. When MBAM is scanning it will look like the image below.
    
    
    
    
    
    
    
13. When the scan is finished a message box will appear as shown in the image below.
    
    
    
    
    
    
    You should click on the OK button to close the message box and continue with the AdvancedDefender removal process.
    
    
14. You will now be back at the main Scanner screen. At this point you should click on the Show Results button.
    
    
15. A screen displaying all the malware that the program found will be shown as seen in the image below. Please note that the infections found may be different than what is shown in the image.
    
    
    
    
    
    
    
    You should now click on the Remove Selected button to remove all the listed malware. MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.
    
    
16. When MBAM has finished removing the malware, it will open the scan log and display it in Notepad. Review the log as desired, and then close the Notepad window.
    
    
17. You can now exit the MBAM program.
    

Your computer should now be free of the AdvancedDefender program. If your current anti-virus solution let this infection through, you may want to consider purchasing the PRO version of Malwarebytes' Anti-Malware to protect against these types of threats in the future.

If you are still having problems with your computer after completing these instructions, then please follow the steps outlined in the topic linked below:
