How To Remove Hackers From Computer Windows 10 : Windows 10 Malware Removal Security Scan

by

Hackers on your Windows 10 computer can steal data, but targeted steps can remove their access and tools. Knowing how to remove hackers from computer windows 10 is crucial for protecting your personal information and restoring your system’s security. This guide provides a clear, step-by-step approach to identify and eliminate threats, even if you’re not a tech expert.

You might be reading this because something feels off. Maybe your computer is slow, you see strange pop-ups, or files have been encrypted. Don’t panic. You can take control back. The process involves disconnecting from the internet, running scans, and cleaning up any malicious software.

We’ll walk through each method, from using built-in Windows tools to free third-party scanners. The goal is to make your system safe again without spending money or needing advanced skills. Let’s get started.

How To Remove Hackers From Computer Windows 10

This section covers the core steps you need to follow. Work through them in order for the best results. Skipping steps might leave a backdoor open for the hacker to return.

Step 1: Disconnect From The Internet Immediately

Your first action is to cut the hacker’s connection. This stops them from sending commands or stealing more data. On a desktop, unplug the Ethernet cable. On a laptop, turn off Wi-Fi by clicking the network icon in the taskbar and selecting “Disconnect.”

If you are using a VPN, disconnect from that too. The goal is to isolate your computer from any network. This simple step can prevent further damage while you work on removal.

Step 2: Boot Into Safe Mode With Networking

Safe Mode loads only essential drivers and services. This prevents most malware from running, making it easier to remove. Here is how to do it:

  1. Restart your computer.
  2. As it boots, press the F8 key repeatedly (or Shift + F8 on some systems) until the Advanced Boot Options menu appears.
  3. If that doesn’t work, restart again and hold the Shift key while clicking “Restart” from the sign-in screen.
  4. Select “Troubleshoot” > “Advanced options” > “Startup Settings” > “Restart.”
  5. After restart, press 5 or F5 for “Safe Mode with Networking.”

This mode gives you internet access for downloading tools, but keeps malicious programs disabled.

Step 3: Run A Full Windows Defender Scan

Windows 10 includes a built-in antivirus called Microsoft Defender. It is quite effective for basic removal. Follow these steps:

  1. Click the Start button and type “Windows Security.”
  2. Open the app and select “Virus & threat protection.”
  3. Under “Current threats,” click “Scan options.”
  4. Choose “Full scan” and click “Scan now.”

This scan can take an hour or more. Let it complete. It will find and quarantine many common threats. After it finishes, review the results and remove any detected items.

Step 4: Use Malwarebytes For A Second Opinion

No single tool catches everything. Malwarebytes is a free scanner that specializes in finding malware that Defender might miss. Download it from the official site (only in Safe Mode with Networking).

  1. Install Malwarebytes.
  2. Open the program and click “Scan.”
  3. Choose “Advanced” and select “Scan for rootkits.”
  4. Let the scan run. It may take 20-30 minutes.
  5. Review the results and quarantine all threats.

Malwarebytes is excellent at removing adware, spyware, and ransomware. Run it even if Defender found nothing.

Step 5: Check For Unauthorized User Accounts

Hackers sometimes create hidden accounts to access your system later. Check for these manually:

  1. Press Windows key + R, type “netplwiz,” and press Enter.
  2. In the User Accounts window, look at the list of users.
  3. If you see any account you didn’t create (like “Admin” or “Guest” with no password), select it and click “Remove.”
  4. Also check the “Users” tab in Computer Management (right-click Start > Computer Management > Local Users and Groups > Users).

Remove any suspicious accounts. Also, change passwords for your legitimate accounts immediately.

Step 6: Review Startup Programs And Scheduled Tasks

Malware often sets itself to run automatically when you start your computer. Disable anything suspicious:

  • Press Ctrl + Shift + Esc to open Task Manager.
  • Click the “Startup” tab.
  • Look for entries with strange names, no publisher, or high “Startup impact.”
  • Right-click and select “Disable” for anything you don’t recognize.

Also check scheduled tasks:

  1. Press Windows key + R, type “taskschd.msc,” and press Enter.
  2. Browse the Task Scheduler Library.
  3. Look for tasks with odd names or triggers that run at logon.
  4. Disable or delete any that seem malicious.

Step 7: Reset Browser Settings And Clear Extensions

Hackers often hijack browsers to redirect you or steal passwords. Reset each browser you use:

For Google Chrome:

  1. Click the three dots > “Settings” > “Reset settings.”
  2. Select “Restore settings to their original defaults” and confirm.

For Microsoft Edge:

  1. Click the three dots > “Settings” > “Reset settings.”
  2. Choose “Restore settings to their default values.”

For Mozilla Firefox:

  1. Click the menu > “Help” > “More troubleshooting information.”
  2. Click “Refresh Firefox.”

After resetting, remove any unknown extensions or add-ons manually from the extensions menu.

Step 8: Check For Rogue Network Connections

Some malware creates outbound connections to command servers. Use the Resource Monitor to spot them:

  1. Press Ctrl + Shift + Esc, then click “Performance” tab.
  2. Click “Open Resource Monitor” at the bottom.
  3. Go to the “Network” tab.
  4. Look for processes with high “Send” or “Receive” values that you don’t recognize.
  5. If you see a suspicious process, note its name and search online to confirm if it’s malicious.

You can also use the command “netstat -ano” in Command Prompt (run as admin) to list active connections. Look for connections to unfamiliar IP addresses.

Step 9: Remove Temporary Files And Clean The System

Malware often hides in temporary folders. Cleaning them can remove remnants:

  1. Press Windows key + R, type “temp,” and press Enter.
  2. Delete all files in the folder that opens. Some may be in use; skip those.
  3. Repeat with “%temp%” (without quotes) in the Run box.
  4. Also type “prefetch” and delete files there.

Then run Disk Cleanup:

  1. Search for “Disk Cleanup” in Start.
  2. Select your system drive (usually C:).
  3. Check “Temporary files,” “Recycle Bin,” and “Delivery Optimization Files.”
  4. Click “Clean up system files” and repeat.

Step 10: Update Windows And All Software

Hackers exploit known vulnerabilities. Keeping everything updated closes those holes:

  • Go to Settings > Update & Security > Windows Update > Check for updates. Install all pending updates.
  • Update your web browsers to the latest versions.
  • Update Adobe Flash, Java, and any other plugins you use.
  • Update your antivirus definitions manually if needed.

After updating, restart your computer normally (not in Safe Mode).

Additional Tools And Techniques

If the above steps don’t fully resolve the issue, you can try more advanced methods. These are still safe for non-experts to use.

Use A Bootable Antivirus Scanner

Some malware is so deep it hides from scans while Windows is running. A bootable scanner runs before Windows loads. Popular options include:

  • Kaspersky Rescue Disk – Free and easy to create on a USB drive.
  • Bitdefender Rescue CD – Also free, works similarly.
  • Microsoft Defender Offline – Built into Windows 10.

To use Microsoft Defender Offline:

  1. Go to Windows Security > Virus & threat protection.
  2. Under “Current threats,” click “Scan options.”
  3. Select “Microsoft Defender Offline scan” and click “Scan now.”
  4. Your computer will restart and run a deep scan before Windows loads.

Check For Rootkits With Specialized Tools

Rootkits are extremely hidden malware. Use these free tools:

  • Malwarebytes Anti-Rootkit – Download from the official site.
  • Sophos Virus Removal Tool – Includes rootkit detection.
  • GMER – A powerful but complex tool for advanced users.

Run these in Safe Mode for best results. They may take a long time but are thorough.

Manually Remove Suspicious Services

If you identified a malicious process earlier, you can stop its service:

  1. Press Windows key + R, type “services.msc,” and press Enter.
  2. Look for services with strange names or no description.
  3. Right-click and select “Properties.”
  4. Click “Stop,” then set “Startup type” to “Disabled.”
  5. If you are sure it’s malware, delete the service using Command Prompt (run as admin) with the command: sc delete ServiceName.

Be cautious. Only delete services you are certain are malicious. Research the name first.

Preventing Future Hacks

Once you have removed the hacker, take steps to avoid being compromised again. Prevention is easier than removal.

Use Strong, Unique Passwords

Weak passwords are an open door. Follow these rules:

  • Use at least 12 characters with a mix of letters, numbers, and symbols.
  • Never reuse passwords across different accounts.
  • Use a password manager like Bitwarden or LastPass to store them securely.

Enable Two-Factor Authentication

This adds an extra layer of security. Even if a hacker gets your password, they can’t log in without the second factor. Enable 2FA on:

  • Your Microsoft account.
  • Email accounts.
  • Banking and social media.

Use an authenticator app like Google Authenticator or Microsoft Authenticator instead of SMS when possible.

Keep Software Updated Automatically

Set Windows Update to install updates automatically. For other software, enable automatic updates where available. This patches vulnerabilities quickly.

Be Cautious With Downloads And Emails

Most hacks start with a user clicking something they shouldn’t. Avoid:

  • Opening email attachments from unknown senders.
  • Clicking links in suspicious emails or messages.
  • Downloading software from unofficial sites.
  • Using cracked or pirated software, which often contains malware.

Use A Firewall And Antivirus

Windows Defender Firewall is already enabled by default. Keep it on. Also, consider a third-party antivirus for extra protection, but don’t run two at once.
