How to Detect and Remove Metamorphic Malware on Windows

Metamorphic malware is one of the most dangerous types of malicious software lurking on the internet. It rewrites its code every time it infects a new system, making traditional antivirus tools struggle to detect or remove it. For Windows users, this kind of malware poses a serious risk to privacy, system stability, and data security. 

We will show you how to detect and remove metamorphic malware from your Windows 10 or 11 system effectively. Plus, we’ll include an extra layer of protection using Fortect, a next-gen tool that goes beyond your typical antivirus solution.

What is Metamorphic Malware?

Metamorphic malware is a form of self-mutating malicious code that changes its internal structure with every iteration. Unlike polymorphic malware, which changes its appearance while maintaining the same code logic, metamorphic malware completely rewrites its code, making detection incredibly difficult. Cybercriminals use this to bypass signature-based detection tools. It’s often embedded in fake software downloads, malicious email attachments, or cracked programs.

What is Self-Mutating Malware?

Self-mutating malware refers to malicious programs that alter their code or appearance to evade detection by antivirus and security software. These types of malware are especially dangerous because their changing nature allows them to stay hidden longer and cause more damage over time.

Common Examples of Self-Mutating Malware:

• Polymorphic Malware – Alters its code superficially (like encrypting parts or changing its appearance) but retains its core logic.
• Metamorphic Malware – Rewrites its entire code with each infection, making it harder to detect than polymorphic variants. Both types are used in advanced persistent threats (APTs) and are known to evolve quickly, which makes them a favorite tool among cybercriminals targeting Windows PCs.

Signs Your Windows PC Might Be Infected

• Unusual system behavior, like programs crashing or slowing down
• High CPU usage even when idle
• Disabled security tools or firewall settings
• Unknown programs or background processes
• Pop-ups or redirects while browsing
• Network activity spikes without reason

How to Detect Metamorphic Malware on Windows?

1. Use Windows Security (Defender)

Windows Security offers a decent first layer of protection:

• Go to Settings > Update & Security > Windows Security.
• Click Virus & threat protection.
• Select Quick scan or Full scan.
• Click Scan options > Microsoft Defender Offline scan for deeper threats.

2. Monitor Task Manager

• Right-click your taskbar > Task Manager.
• Look for unfamiliar processes using high CPU or memory.
• Right-click the process > Open file location. If it’s on a suspicious path, research the file.

3. Check Startup Items

• Press Ctrl + Shift + Esc > go to Startup tab.
• Disable suspicious entries and research unknown publishers.

4. Use SFC and DISM to Check for System Damage

• Open Command Prompt as Administrator.
• Run: sfc /scannow
• Then: DISM /Online /Cleanup-Image /RestoreHealth These tools repair corrupted system files often affected by malware.

How to Remove Metamorphic Malware?

Step 1: Boot into Safe Mode

• Go to Settings > Update & Security > Recovery.
• Under Advanced Startup, click Restart now.
• Go to Troubleshoot > Advanced options > Startup Settings.
• Press F4 for Safe Mode.

Step 2: Manually Delete Suspicious Files

• Navigate to C:\Users\YourName\AppData\Roaming and Temp folders.
• Delete files or folders related to unknown programs.
• Use msconfig to disable unnecessary startup entries.

Step 3: Create a New User Account (if infected account is damaged)

• Go to Settings > Accounts > Family & other users.
• Click Add someone else to this PC.
• Follow the prompts to create a new admin account.
• Log into the new account and delete the old, infected one (optional).

Step 4: Update Windows

Keeping Windows updated is crucial:

• Go to Settings > Update & Security > Windows Update.
• Click Check for updates and install everything available.
