Sysinternals Antivirus is a rogue program from the Your PC Protector family. This rogue program is actually classified as ransomware and scareware rather than malware or spyware because of the way it behaves. The rogue program installs itself onto your computer without you knowing about it through other malware programs, usually from a website that you have visited. The main goal of the rogue program is to scare you into thinking that your computer is infected, but truth is the only problem is Sysinternals Antivirus.
Once Sysinternals Antivirus has been installed on your computer the rogue program is going to perform a scan, but the results from this scan are not going to be accurate, they are just used to try to scare you into thinking your computer is thoroughly infected with a variety of threats. Once the scan is done and you see the results the scan is going to tell you something along the lines of you need to purchase the program in order to remove any of the threats that were detected. Never purchase the program because the only thing wrong with your computer is it is infected with Sysinternals Antivirus.
Something else to be aware of is if your computer is infected with Sysinternals Antivirus, the rogue program is going to do everything that it can to protect itself. If you try running an antivirus program or even a malware removal program the rogue program is going to block access to those programs so that they cannot run. When trying to run a legitimate program you will get a popup that states the program cannot run because it is infected. Along with these popup warnings you will also see other alerts such as

In order to automatically remove Sysinternals Antivirus you are going to need to install a spyware removal program, if you haven't done so already.
