If your computer is suddenly running slow, showing suspicious pop-ups, or your browser is redirecting you to unknown sites, you need to know how to remove malware from Windows 10 immediately. In 2026, cyber threats have evolved; modern “Polymorphic” malware and “ClickFix” social engineering tactics require a strategic approach to clean your system.
At WiTechPedia, we prioritize your digital safety. This guide provides a vetted, professional workflow to purge infections and harden your OS. If you are also managing a website, you might want to check our insights on AI Cybersecurity Threats & Defenses in 2026.
Is Your PC Infected? (The Symptoms Checklist)
Before diving into the removal steps, check for these “Red Flags” of a compromised system:
- Disabled Antivirus: Your Windows Security won’t turn on.
- High CPU Usage: Your fan is loud, and Task Manager shows 100% usage.
- Unauthorized Redirects: Your search engine has changed mysteriously.
Emergency Response: If you suspect a deep infection, disconnect from the Internet. This prevents the malware from communicating with its Command and Control (C2) server.
1. Enter Safe Mode with Networking
Many modern malware strains protect themselves by running as active processes. Safe Mode starts Windows with a minimal set of drivers.
- Go to Settings > Update & Security > Recovery.
- Under Advanced startup, click Restart now.
- Choose Troubleshoot > Advanced options > Startup Settings > Restart.
- Press 5 or F5 to start in Safe Mode with Networking.
2. Use Built-in Windows Security Tools
Windows 10 includes powerful tools that can perform deep-level cleaning without needing 3rd party software.
Step A: Windows Defender Offline Scan
This is the “Gold Standard” for how to remove malware from Windows 10. It catches stealthy rootkits that hide while the OS is active.
- Open Windows Security and go to Virus & threat protection.
- Click Scan options and select Microsoft Defender Offline scan.
- For a deeper dive into system tools, see our 25 Essential CMD Commands Guide (Internal Link).
Step B: Microsoft Malicious Software Removal Tool (MSRT)
Microsoft updates this tool monthly. You can trigger it manually:
- Press Windows Key + R, type
mrt, and hit Enter. - If the tool is missing, you can download the latest version from the official Microsoft Download Center (External Link).
3. Professional 2026 Removal Methods
In 2026, we are seeing a rise in “Fileless” malware that lives in your Registry.
- Clear Temporary Files: Malware often hides in your temp folders. Use Disk Cleanup to purge these files.
- Check Your Activation Status: An unactivated system often misses critical security infrastructure updates. If you see activation errors, follow our guide on how to activate Windows 10 for free.
- Verify System Files: Use the
sfc /scannowcommand to repair files corrupted by viruses. Learn how to run this in our Hardware & Software Troubleshooting Wiki
4. Prevention: Keeping Malware Out for Good
Once clean, you must harden your system. Refer to the Microsoft Security Best Practices for enterprise-level advice on home PCs.

Can malware survive a Windows 10 Factory Reset?
Most cannot, but advanced bootkits can. If you’re worried, perform a clean install using our Official Windows 10 Installation Guide.
Is Windows Defender enough in 2026?
Yes, but for stubborn infections, we recommend a second opinion using the Microsoft Safety Scanner.
