Technical analysis of SMLHelper64.exe and x64dbg.exe files

Technical documentation provides guidance on identifying and verifying two specific Windows executable files: SMLHelper64.exe and x64dbg.exe.

SMLHelper64.exe is a 64-bit component of the 360 Software Assistant, part of the Qihoo 360 Total Security suite developed by Qihoo 360 Technology. While legitimate when located in the official program files directory, the file should be treated as suspicious if found in system folders like System32, Temp, or Downloads.

x64dbg.exe is the 64-bit executable for x64dbg, an open-source user-mode debugger used by developers and malware analysts. Users are advised to verify the source of the file, as unexpected copies in temporary or user-profile folders may be untrusted. Common issues with the debugger include signature errors on Windows 7 and plugin compatibility problems.
