## What is Sysinternals Antivirus?

Skip this and learn how to remove Sysinternals Antivirus!

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.

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:

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

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.
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.

## Self Help Guide

This guide contains advanced information, but has been written in such a way so that anyone can follow it. Please ensure your data is backed up before proceeding.

If you are uncomfortable making changes to your computer or following these steps, do not worry! Instead you can get free one-on-one help by asking in the forums.
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, please download RKill to your desktop from the following link.

Do not reboot your computer after running RKill as the malware programs will start again.

7. Double-click on the icon on your desktop named mb3-setup-1878.1878-3.0.6.1469.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 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 start and you will be at the main screen as shown below.

Please click on the Scan Now button to start the scan. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.

10. MBAM will now start scanning your computer for malware. This process can take quite a while, so we suggest you do something else and periodically check on the status of the scan to see when it is finished.

11. When MBAM is finished scanning it will display a screen that displays any malware that it has detected. Please note that the infections found may be different than what is shown in the image below due to the guide being updated for newer versions of MBAM.

You should now click on the Remove Selected button to remove all the seleted 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.

12. You can now exit the MBAM program.

13. 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:

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.
