Have you ever opened Windows Task Manager and noticed a process you don't remember installing?
You close it.
You restart your computer.
And there it is again.
The first thought is usually:
"Is my computer infected?"
Not necessarily.
Windows, drivers, software updaters, security tools, and legitimate applications can all start processes automatically.
The important question isn't simply whether you recognize the process.
It's:
Why is it starting, where is it running from, and what is causing it to appear?
I built SysPulse around this exact kind of visibility problem. It is a lightweight Windows security monitor designed to help you notice unusual system activity instead of discovering it only after something goes wrong.
You can explore the project through SysPulse Website or see the documentation and screenshots on SysPulse GitHub.
Let's investigate the problem step by step.
1. Start With the Process Name
Open Task Manager with:
Ctrl + Shift + Esc
Then open the Processes or Details tab.
Look for the process that keeps appearing.
For example:
example.exe
Don't immediately assume that an unfamiliar name means malware.
Windows can have hundreds of processes running in the background, and third-party applications can create their own processes as well.
However, an unfamiliar process becomes more interesting when several things happen at the same time:
- You don't remember installing the application
- The process starts automatically
- The executable is stored in an unusual location
- There is no identifiable publisher
- It repeatedly returns after being terminated
- Other unusual activity happens at the same time
A single indicator rarely tells the whole story.
2. Check the Executable Location
The process name is only part of the investigation.
Right-click the process and select:
Open file location
Now look at the actual executable path.
For example:
C:\Program Files\Example\example.exe
The location can provide useful context about which application owns the process.
But don't make the mistake of assuming:
"System32 means safe, everything else means malware."
That's not how Windows security works.
Legitimate applications can run from many different directories.
The file path is simply another piece of evidence.
3. Check the Digital Signature
Right-click the executable and open:
Properties → Digital Signatures
If the file is digitally signed, inspect the publisher.
A recognizable publisher can help explain where the program came from.
But don't treat the signature as absolute proof.
An unsigned file isn't automatically malicious, and a signed file isn't automatically trustworthy.
Security investigation works better when you combine multiple signals.
4. Why Does It Start Every Time Windows Boots?
This is probably the most important question.
If the same process appears after every reboot, something is launching it automatically.
Start by checking:
Settings → Apps → Startup
You can also check:
Task Manager → Startup apps
Look for applications you don't recognize.
But Windows has more startup mechanisms than the normal Startup list.
A program may also be launched through:
- Windows Services
- Scheduled Tasks
- Registry startup entries
- Startup folders
- Software updaters
- Other applications
So an empty Startup list doesn't necessarily explain everything.
5. Use PowerShell to Investigate
PowerShell can provide useful information about running processes.
For example:
Get-Process | Select-Object Name, Id, Path
This gives you the process name, process ID, and executable path when Windows allows the information to be retrieved.
For a specific process:
Get-Process -Name "example" | Select-Object Name, Id, Path
Replace example with the actual process name.
PowerShell is particularly useful when you want to investigate Windows without installing another utility.

6. What If the Process Keeps Coming Back?
This is where things become more interesting.
Suppose you terminate:
example.exe
A few seconds later:
example.exe
appears again.
Instead of repeatedly killing it, ask:
What is restarting it?
Possibilities include:
- A Windows service
- A scheduled task
- An updater
- Another application
- A startup mechanism
- A security product
The fact that a process returns doesn't automatically mean malware is present.
But it tells you that something else is responsible for launching it.
That relationship can be much more informative than the process itself.

7. Don't Forget Hidden Programs
Sometimes the process you notice isn't the actual application you are looking for.
A background component may be launched by another program.
This is why checking only the visible desktop applications isn't enough.
Windows can have:
- Background services
- Helper processes
- Update agents
- Scheduled components
- Tray applications
- Driver-related processes
For another practical guide, see How to Find Hidden Programs Running on Windows Before They Become a Security Problem.
The important idea is simple:
Visibility matters.
You can't investigate something you never notice.
8. What About Windows Defender?
If an unfamiliar process concerns you, don't immediately delete the executable.
First check Windows Security.
Open:
Windows Security → Virus & threat protection
Make sure protection is enabled and review any recent detections.
You should also pay attention if Windows Defender suddenly becomes disabled without an obvious reason.
That doesn't automatically prove an infection, but unexpected security-status changes deserve investigation.

9. Why Manual Checking Isn't Always Enough
There's a limitation with Task Manager:
It shows you what is happening right now.
Imagine a suspicious process starts at:
10:42:13
and exits at:
10:42:17
If you open Task Manager at 10:42:30, you may never see it.
That's the difference between a snapshot and monitoring.
Manual investigation is useful when you already know what you're looking for.
Continuous monitoring is useful when you don't.
10. A Different Approach: Monitor Changes
Instead of constantly asking:
"What processes are running?"
a security monitor can focus on:
"What changed?"
For example:
New Process Detected
Process: example.exe
Path: C:\Program Files\Example\example.exe
Time: 20:41
Now you have something concrete to investigate.
You can determine:
- What program created it
- Where it came from
- Whether you installed it
- Whether its publisher is legitimate
- Whether it should start automatically
This is the philosophy behind SysPulse.
It doesn't try to tell you that every unfamiliar process is malware.
Instead, it is designed to make unusual Windows activity easier to notice.
11. Detection Is Not the Same as Investigation
These are two different problems.
Detection asks:
"Did something unusual happen?"
Investigation asks:
"What exactly happened, and is it legitimate?"
For example, detecting:
New process detected
is useful.
But knowing:
Process: example.exe
Path: C:\Program Files\Example\example.exe
Time: 20:41
gives you much more context.
A useful security workflow therefore looks something like:
Detect
↓
Identify
↓
Investigate
↓
Decide
The goal isn't to panic every time Windows starts something new.
The goal is to have enough information to make a reasonable decision.
What Should You Do If You Don't Recognize a Process?
Don't immediately delete it.
Instead:
Step 1
Record the exact process name.
Step 2
Find the executable path.
Step 3
Check the publisher and digital signature.
Step 4
Check startup mechanisms.
Step 5
Run an appropriate Windows Security scan.
Step 6
Look for other unusual activity around the same time.
Step 7
If the process repeatedly returns, investigate what is launching it.
This approach is much safer than randomly deleting files from Windows directories.
Final Thoughts
An unknown process isn't automatically malware.
At the same time, an unfamiliar process that repeatedly appears after startup shouldn't simply be ignored.
The most useful clues are usually found by combining:
Process name + executable path + publisher + startup mechanism + behavior + security status
Task Manager is excellent for quick inspection.
PowerShell can help with deeper investigation.
Windows Defender provides an important layer of malware protection.
And continuous monitoring can help you notice changes that a manual check might miss.
That's why I built SysPulse.
The idea is simple:
You shouldn't have to constantly watch Task Manager to know when something changes on your Windows PC.
If a new or unusual program appears, having that event brought to your attention gives you a starting point for investigation.

Final Thought
If your Windows PC keeps starting a process you don't recognize, don't start by deleting it.
Start by asking:
Why does it exist?
Where did it come from?
What is launching it?
Sometimes the explanation is completely harmless.
And sometimes, noticing an unexpected process early gives you the opportunity to investigate before a small problem becomes a much bigger one.
