Yes, but unlikely. Legitimate software sometimes uses internal build names (setup45367.exe), but usually not with a Sp prefix. Some old printer drivers (HP, Samsung) used Sp*.exe for “Setup Package” files — but those are normally in C:\SWSetup or similar, not Temp folders.
Given the behavior, I’m treating this as malware until proven otherwise.
If you find Sp45367.exe (or any suspicious process with a random numeric name):
Now that we know what it is, the question remains: should you keep it?
The Short Answer: If your Bluetooth is working fine, you can delete the installer file, but keep the drivers installed.
The Long Answer:
sp45367.exe is a specific software package from HP that contains the Intel Local Management Service (LMS) Serial-over-LAN (SOL) What it does This executable is used to provide support for Intel Active Management Technology (AMT)
on various HP desktop models. If you see a "PCI Serial Port" or "PCI Simple Communications Controller" with a yellow exclamation mark in your Windows Device Manager, this driver is often the fix. Key Details HP (Hewlett-Packard). Primary Function: Installs Intel LMS and SOL drivers. Target Hardware: Commonly used for older business desktops like the HP Compaq 6000 Pro HP Compaq 8000 Elite Operating Systems: Sp45367.exe
Supports Windows 7, and is often used manually for Windows 10 compatibility on legacy machines. How to use it If the standard installer fails, community experts on the HP Support Community Extract the file using a tool like Device Manager
, right-click the "PCI Serial Port," and select "Update driver".
Choose "Browse my computer for drivers" and point it to the extracted folder. direct download link

"Sp45367.exe" is, by its name and form, representative of a class of Windows executable filenames that populate modern computing environments—some benign, many malicious, and many ambiguous. Filenames like this one, composed of letters and digits with an .exe extension, can function as a neutral program identifier or as a deliberate obfuscation tactic used by attackers to hide code, persistent services, or payloads. This essay examines possible origins, typical behaviors, investigative approaches, and broader implications for users and defenders.

Conclusion "Sp45367.exe" symbolizes the ambiguity endemic to modern endpoints: a filename alone is not definitive proof of intent. Effective assessment combines metadata, behavioral telemetry, provenance, and context. For defenders, the path forward emphasizes robust detection across static and dynamic dimensions, rapid response procedures, and user-facing practices that reduce the chance of accidental execution of unknown binaries.

A few days ago, I noticed a process running on my Windows machine that I didn’t recognize: Sp45367.exe.
It wasn’t there last week. No new software installs. No USB drives plugged in. Just… there, sitting in Task Manager, using a steady 12% CPU and about 80 MB of RAM.
If you’ve ever seen a random .exe with a name that looks like an internal build tag or a serial number, you know the first rule: don’t double-click it.
If Sp45367.exe is part of a legitimate driver installer:
You likely have a dropper or scheduled task recreating it. Run a full antimalware scan and check Task Scheduler for unfamiliar triggers.
A legitimate Sp45367.exe typically resides in:
If you find Sp45367.exe in C:\Windows\System32 or C:\Windows\SysWOW64 without a valid digital signature, exercise caution. Yes, but unlikely
