Managing Risk


Advanced Techniques


The guidance in IT Pro Advanced Techniques helps IT professionals investigate, analyze, and—when possible—remove malware from an infected computer. This guidance, intended for advanced users, helps IT professionals understand the impact of malware and create a rudimentary roadmap for cleaning infected computers. In addition, this effort provides the user more information about the internal operation of malware.

The guidance involves the use of several Windows Sysinternals tools, a suite of advanced diagnostics and troubleshooting utilities for the Windows platform available for download at no charge from the Microsoft Download Center.

How to remove Smart Guard Protection Part 2

How to remove Smart Guard Protection Part 1




Here is another way to disable and remove this fake antivirus

Copy Task Manager to Windows folder and rename it as CMD.exe


Launch the renamed file and terminate the fake AV process.  Smart Guard Protection will not block CMD.exe.  You can also copy File Assassin or any program to the Windows folder and rename it to trick Smart Guard Protection.


Now that the fake AV is no longer running in the background, we can start deleting the files and registry entry to prevent it from starting with Windows again

On your Desktop right click on Smart Guard Protection icon and click Properties.  Click the Find Target... button.  This will launch explorer to the location of the fake AV file.  Delete the entire folder.


Launch regedit and navigate to

HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce

Delete the value AS2014 


Alternative:  If you have CCleaner, launch it and go to Tools | Startup and delete AS2014


Scan your computer with MBAM to reverse the changes made by Smart Guard Protection.  Here is the result of the scan.
