File indicates potential issues with rundll32.exe.
Hello! I usually check my task manager and almost remember all the apps, but today I noticed rundll32.exe running and got an alert. After looking around, I found it in several locations: System32, sysWOW64, WinSxS\x86_microsoft, and another in amd64_microsoft. I’m curious why I have the amd64 version even though my PC is Intel and has NVIDIA. I don’t want to post here about viruses, but I think I’ll get better answers from you guys.
amd64 refers to a computing architecture, unrelated to the specific hardware you're using. rundll32.exe is a Windows application that runs on your operating system.
I understand it involves a process on Windows, but typically you don’t have more than one copy of the same file. I’ve also learned that Rundll32.exe is often used by malware to disguise itself. Additionally, the term “amd64” refers to a specific architecture that keeps evolving.
If you're concerned about a potential virus, perform an antivirus scan and a malware scan using MalwareBytes. If both scans show no issues, everything appears safe.
The rundll32.exe service handles loading DLLs and storing their libraries in memory. It functions as a command-line tool that works with rundll.exe, using the LoadLibrary() function to retrieve the required DLL. The process reads the command line arguments and uses GetProcAddress() to fetch the needed functions. When the task completes, the DLL is removed from memory.
