What You’ll Need
Before we get started, here’s what you’ll need:
- A Windows computer
- Antivirus software (Windows Security or another trusted program)
- An internet connection
- About 20–45 minutes, depending on the scan
👉 If you don’t have antivirus (affiliate link for U.S. and Canada only) installed yet, install one first before continuing.
Step-by-Step Instructions
1. Save and close all open programs
Close everything you’re working on to avoid interruptions.
2. Disconnect from the internet
Turn off Wi-Fi or unplug your Ethernet cable.
👉 This helps prevent malware from spreading or communicating.
3. Click the Start menu
Click the Windows icon in the bottom-left corner.
4. Type “Windows Security”
Start typing until you see Windows Security appear.
5. Click on Windows Security
Open the app.
👉 You should see the main security dashboard.
6. Click “Virus & threat protection”
Find and click this option.
7. Click “Scan options”
Look below the Quick scan button.
8. Select “Full scan”
Choose the Full scan option.
👉 This checks your entire system for malware.
9. Click “Scan now”
Start the scan.
10. Wait for the scan to complete
Let the scan (affiliate link for U.S. and Canada only) run without closing the window.
👉 Your computer may slow down, and the scan may take a while. If needed, see these tips for speeding up your computer.
11. Review the scan results
Wait for the results to appear.
👉 You should see either “No threats found” or a list of detected threats.
12. Click “Start actions”
If threats are found, click this to remove them.
13. Follow any on-screen instructions
Complete any additional steps shown.
14. Restart your computer
Restart if prompted.
👉 Your screen may go black briefly—this is normal.
15. Reconnect to the internet
Turn your Wi-Fi or Ethernet back on.
16. Run a second scan
Repeat the scan to make sure everything is clean.
👉 You should see fewer or no threats this time.
What to Expect During Malware Removal
Here’s what you might notice:
- A progress bar showing scan progress
- Your computer running slower during the scan
- Notifications if malware is found
- Prompts asking you to remove or quarantine threats
👉 If malware is found, don’t panic—this means your antivirus is doing its job.
If malware is not found but your system still seems slow try to disable startup programs. If that doesn’t appear to be the problem scan your pc for viruses again.
