How to remove Sysinternals Antivirus (Removal guide)

Sysinternals Antivirus is a new rogue antispyware program from the same family of malware as XJR Antivirus, AKM Antivirus 2010, etc. The malicious program usually installed itself onto your computer without your permission and knowledge, with the help of trojans. When the trojan is started, it will download and install Sysinternals Antivirus onto your computer.

During installation, Sysinternals Antivirus will create a malicious service called “Adobe Update Service (AdbUpd)” that will start automatically every time when Windows loads. Once started, it will run the “Sysinternals Antivirus.exe” program, which is a core part of the rogue. Once installation process is complete, the rogue will perform a system scan and “detect” a lot of infected files, trojans, worms, and so on, that will not be fixed unless you first purchase the full version of the program. Of course this is not necessary. The scan results, as well as the “system scan”, is nothing but a scam. In reality Sysinternals Antivirus cannot detect and remove any infections, as well as not be able to protect you from possible infections in the future. Thus, you can safely ignore all that the rogue antispyware will show you.

While Sysinternals Antivirus is running, it will display a fake Windows Security Center and a wide variety of alerts, reminders, security messages from Windows task bar that stats:
