System Defragmenter Virus

Automated Removal Instructions for System Defragmenter 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 System Defragmenter 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. Once it is downloaded, double-click on the rkill.com in order to automatically attempt to stop any processes associated with
   System Defragmenter 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 System Defragmenter
   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 System Defragmenter. 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.

5. 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)

Then click on the Finish
   button. If MalwareBytes’ prompts you to reboot, please do not do so.
9. 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.
   
10. 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 System Defragmenter related files.

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.
