How to Remove Virus From Laptop – If your laptop has ever suddenly become slow, started showing strange pop-ups, or opened things you didn’t click, you know how frustrating and even scary it can feel. That was exactly what happened to me some time ago. I was trying to download a “free” software online.
Everything looked normal at first. But within a short time:
- My laptop became very slow
- Strange adverts started popping up
- My browser homepage changed by itself
- Some of my files disappeared
At that moment, I realized I had unknowingly installed a virus. That experience forced me to learn how to remove virus from laptop properly and, more importantly, how to prevent it from happening again.
In this guide, I will walk you through everything — in a simple way — so that no matter where you are in the world, you can detect a virus early, remove it safely, and protect your laptop from now on
Let’s begin.
What is a Computer Virus?
A computer virus is a harmful program designed to:
- Damage your system
- Steal your information
- Spy on your activity
- Slow down your laptop
- Control your device without your permission
Think of it like a sickness in your body. If you don’t treat it early, it can spread and become worse.
Common Ways Viruses Enter Your Laptop
Most infections happen because of everyday actions like:
- Downloading free cracked software
- Clicking unknown links
- Opening suspicious email attachments
- Using infected USB drives
- Visiting unsafe websites
Even smart people fall into this. So don’t feel bad if it has happened to you.

Before you remove a virus, you must first recognize it. So you have to watch out for these signs:
- The laptop suddenly becomes slow
- Too many pop-up ads
- New programs appear without installing them

My personal experience
In my own case:

- I saw ads even when I wasn’t browsing
That was when I knew something was wrong.

How To Remove Virus From Laptop
Now, let’s go into the real solution. Make sure to adhere to the steps given below carefully.
Step 1: Start Your Laptop In Safe Mode
Safe Mode allows your laptop to run with only basic programs, making it easier to remove viruses. Safe Mode is a special way of starting your laptop where only the essential system programs run. This makes it easier to detect and remove viruses because most malware will not run in Safe Mode.
How to Enter Safe Mode
There are two easy methods you can use depending on your situation.
Method 1: Using Shift + Restart (Easiest Method)
This is the most reliable method for Windows 10 and Windows 11.
Follow these steps carefully:
- Save your work
Before restarting your laptop, make sure you:
Save any open documents
Close all programs
This prevents data loss.
- Open the Power Menu
- Click the Start button (Windows icon at the bottom left of your screen).
- Then click on the Power icon.
- Hold the SHIFT key and click Restart
Now do this:
- Press and hold down the SHIFT key on your keyboard
- While holding SHIFT, click Restart
Do not release the SHIFT key until your laptop starts restarting.
- Wait for the Advanced Options screen
Your laptop will restart and show a blue screen with options.
You will see something like:
Continue
Troubleshoot
Turn off your PC
Click: Troubleshoot
- Go to Advanced Options
- On the next screen, click: Advanced Options
- Open Startup Settings
- Next, click: Startup Settings
- You will now see information about startup options like Safe Mode.
- Click Restart again
- At the bottom of the screen, click: Restart
Your laptop will restart again.
- Select the Safe Mode option
After restarting, you will see a list of numbered options like:
1 – Enable debugging
2 – Enable boot logging
3 – Enable low-resolution video
4 – Enable Safe Mode
5 – Enable Safe Mode with Networking
6 – Enable Safe Mode with Command Prompt
At the bottom of the screen, click: Restart
Your laptop will restart again.
- Press number 4 on your keyboard to enter Safe Mode
OR
- Press number 5 to enter Safe Mode with Networking (this allows internet access)
Which Safe Mode Should You Choose?
Choose Safe Mode (Option 4) if you just want to remove the virus offline
Choose Safe Mode with Networking (Option 5) if you need the internet to download antivirus tools
Method 2: Using F8 Key (Older Method – May not work on All Laptops)
Some older laptops allow Safe Mode using the F8 key.
Steps:
Turn off your laptop
Turn it on again
Immediately start pressing the F8 key repeatedly
A menu will appear
Select Safe Mode
Note: On many newer laptops, F8 is disabled by default, so this method may not work.
How to Confirm You Are in Safe Mode
When Safe Mode is active, you will notice:
- The screen looks simple
- The background may be black
- The words “Safe Mode” appear at the corners of your screen
- Only basic programs are running
This confirms that you are now in Safe Mode.
Step 2: Delete Temporary Files
Viruses sometimes hide in temporary files. So you have to do this:
- Press Windows + R
- Type temp
- Delete everything
Repeat for:

Step 3: Run Windows Security Scan
Windows has a built-in antivirus. To run the scan, simply follow the steps below.

Step 4: Use a Strong Antivirus Tool
For better cleaning, install a trusted antivirus such as:

Run a full scan and remove all threats found.
Step 5: Remove Suspicious Programs
Go to Control Panel → Programs
Uninstall anything:

- Recently installed without your knowledge
Step 6: Clean Your Browser
Viruses often affect browsers.
Do this:
- Remove strange extensions
- Reset browser settings
- Clear history and cookies
Step 7: Disable Virus Startup Programs
- Press Ctrl + Shift + Esc
- Open Task Manager
- Click Startup
- Disable unknown programs
Step 8: Scan Again
After cleaning, run another full scan to be sure your laptop is now clean.
Alternative Options if the Virus Remains
After taking the steps above and the virus still does not go away, it means the infection is strong, so use these options;

Restore your laptop to a previous safe date.
