🔍 How to Identify Suspicious Processes in Windows
Simple, understandable and practical guide to Task Manager – ideal for beginners
Do you really know what programs are currently running on your computer?
Every time you turn on your computer, Windows automatically starts many processes in the background. Most of them are completely normal and necessary for the system to function properly, even if you don't see them on the screen.
However, in some cases, a suspicious or malicious program may be "hidden" among them. Such programs can slow down your computer, display annoying ads, open pages without your consent, or even compromise your personal data.
In this detailed guide, you will learn, in simple words and without difficult technical terms, how to check what is "running" on your computer through the Task Manager and how to distinguish normal processes from those that need attention.
📋 What are Processes?
Simply put, every program you open on your computer creates one or more processesFor example, when you open a browser to access the Internet or a document program, Windows starts the necessary processes for the program to function properly.
At the same time, Windows constantly runs many processes in the background, even when you don't have any programs open. These take care of basic functions such as: sound, internet, devices, updates, and system security.
The problem starts when a process appears that is not related to a known program or basic Windows function and runs without you knowing it.

🚨 Suspicious Signs to Watch Out For
🔴Danger signs
📚 Examples: Normal vs Suspicious Processes
✅ Normal Processes (Safe)
What is: A core Windows process that runs many system services.
Location: C: \ Windows \ System32 \
Note: It is normal for there to be many copies of it.
What is: Manages the desktop, folders, and taskbar.
Location: C: \ Windows \
What is: Critical Windows process.
Important: It never ends.
What is: Basic operation for Windows windows.
Location: C: \ Windows \ System32 \
❌ Suspicious Processes (Caution!)
Why: It pretends to be svchost.exe but with a different character.
Possible cause: Malicious add-ons or problematic programs.
Why: System32 is a folder, not a regular process.
🔧 How to Investigate a Suspicious Process
Step 1: Open file location
Right-click on the process and select “Open file location.” This way you can see exactly which folder the file that runs it is located in. The location of the file is one of the most important pieces of information to understand whether something is safe or not.
Usually safe locations:
- C: \ Windows \ System32 \
- C: \ Windows \
- C: \ Program Files \
- C: \ Program Files (x86) \
If a process is located in one of the above folders, in most cases it is a legitimate and safe program.
Places that need attention:
- C:\Users\[Your Name]\AppData\Local\Temp\
- C:\Windows\Temp\
- Folders with random or strange names
- The desktop
If a process starts from such folders, it doesn't necessarily mean it's malicious, but it definitely needs closer inspection.
Step 2: Search the internet
You copy the process name and search for it on Google. You will usually find clear information, experiences of other users, and answers about whether it is a safe program or not.
Step 3: Publisher check
In Task Manager, there is a column that shows which company created the process. Genuine Windows processes list Microsoft, while well-known programs list their respective company.

Task Manager covers most users' needs. However, Microsoft offers a more advanced tool, Process Explorer, that shows in much greater detail what's really going on on your computer.

2. Search for the Process Explorer tool
3. Download and open it without installation
