What this infection does:

Sysinternals Antivirus is a scareware and ransomware program from the same family as Your PC Protector. This program is installed through the use of malware that will install it onto your computer without your permission or knowledge. Once installed, Sysinternals Antivirus will automatically perform a scan when your computer starts. When the scan has finished it will state that your computer is infected with numerous infections, but will not allow you to remove anything until you first purchase the program. As the scan results are all fake and are only being shown to scare you into purchasing the software, you should ignore them and instead use this guide to remove the program.

For more screen shots of this infection click on the image above.
There are a total of 7 images you can view.

While Sysinternals Antivirus is running it will protect itself by blocking your ability to run many applications. It does this so that you cannot launch legitimate security programs that may remove it. When you attempt to run a program that it blocks you will see a message stating:

Warning!
Running of application is impossible.<Application Name> is infected.

Once the Sysinternals Antivirus process is terminated, you will once again be able to use your normal applications.

While started, Sysinternals Antivirus will also show fake security warnings that state your computer is under attack or that malware has been found. The text of these messages is:

Security Alert
Infiltration Alert
Your computer is being attacked by an Internet Virus. It could be a password-stealing attack, a trojan-dropped or similar.

Warning: Infection is Detected
Windows has found spyware infection on your computer! Click here to update your WIndows antivirus software...

svchost.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
If you were in the middle of something, the information you were working on might be lost.
Please tell Microsoft about this problem.
We have created an error report that you can send to us. We will treat this report as confidential and anonymous.

All of the above alerts are fake and are only being shown to scare you into thinking that you have a security problem and should be ignored.

Without a doubt, Sysinternals Antivirus was created to scare you into purchasing the program by showing alerts stating that you are infected. Please disregard any warnings this program shows and do not purchase the program. If you have already purchased it, we suggest you contact your credit card company and dispute the charge. To remove this infection please use the removal guide below.

Automated Removal Instructions for Sysinternals Antivirus 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 Sysinternals Antivirus 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 Sysinternals Antivirus 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 Sysinternals Antivirus 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 Sysinternals Antivirus . 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)
   
   


6. Once downloaded, close all programs and Windows on your computer, including this one.
   
   
7. Double-click on the icon on your desktop named mbam-setup.exe. This will start the installation of MBAM onto your computer.
   
   
8. 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.
   
   
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 Sysinternals Antivirus related files.
    
    
11. 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.
    
    
    
    
    
    
    
12. 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 Sysinternals Antivirus removal process.
    
    
13. You will now be back at the main Scanner screen. At this point you should click on the Show Results button.
    
    
14. 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.
    
    
15. 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.
    
    
16. You can now exit the MBAM program.
    
    
17. As many rogues and other malware are installed through vulnerabilities found in out-dated and insecure programs, it is strongly suggested that you use Secunia PSI to scan for vulnerable programs on your computer. A tutorial on how to use Secunia PSI to scan for vulnerable programs can be found here:
    
    How to detect vulnerable and out-dated programs using Secunia Personal Software Inspector

Your computer should now be free of the Sysinternals Antivirus 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.
