A keylogger is one of the most dangerous types of malware because it operates silently in the background, recording every single keystroke you type. This includes passwords, credit card numbers, and private messages. If you suspect your computer is behaving strangely or your accounts have been accessed without permission, you may have a keylogger installed. Here is a step-by-step guide to finding and removing them.

Step 1: Check for Suspicious Processes in Task Manager

The first place to look for software-based keyloggers is your system's active processes. While many keyloggers try to hide, some appear as unrecognized background tasks.

• Press Ctrl + Shift + Esc to open the Task Manager.
• Click on More details if the window is small.
• Go to the Processes tab and look for apps or background processes with strange names or high CPU usage.
• Right-click any suspicious process and select Search online to see if it is documented malware.
• If it is confirmed malicious, click End Task.

Step 2: Scan with a Specialized Anti-Malware Tool

Standard antivirus software sometimes misses sophisticated keyloggers. You need a dedicated malware removal tool to perform a deep system scan.

• Download and install a reputable tool like Malwarebytes or HitmanPro.
• Boot your computer into Safe Mode with Networking (Hold Shift while clicking Restart > Troubleshoot > Advanced Options > Startup Settings).
• Run a Full System Scan.
• Follow the prompts to Quarantine or Delete any detected threats.

Step 3: Inspect Your Physical Hardware

Keyloggers aren't always software. If you use a desktop PC, a hardware keylogger could be plugged directly into your machine.

• Check the back of your PC where your keyboard connects.
• Look for any unfamiliar adapters or USB devices plugged in between the keyboard cable and the USB port.
• If you find a suspicious device, remove it immediately. These devices physically record data and do not show up in software scans.

Step 4: Analyze Your Startup Programs

Keyloggers need to start every time you turn on your computer. You can block them by checking your startup list.

• Open Task Manager and navigate to the Startup tab.
• Look for items labeled as "Unknown" or programs you don't recognize.
• Select the suspicious item and click Disable.
• Press Windows Key + R, type shell:startup, and press Enter. Ensure no strange shortcuts are located in this folder.

Step 5: Reset Your Web Browsers and Clear Cache

Some keyloggers function as malicious browser extensions. Even if you clean the OS, the browser might still be compromised.

• Open your browser (Chrome, Edge, or Firefox).
• Navigate to the Extensions or Add-ons menu.
• Remove any extension you did not personally install.
• Go to Settings and select Reset Settings to restore the browser to its original state.

Step 6: Secure Your Accounts Post-Removal

Removing the keylogger is only half the battle. If the logger was active, your credentials are likely compromised.

• From a different, clean device, change all your major passwords (Email, Banking, Social Media).
• Enable Two-Factor Authentication (2FA) on every account that supports it. Use an authenticator app rather than SMS for better security.
• Monitor your bank statements for any unauthorized transactions.

💡 Pro Tip: Keep your software updated to avoid these issues in the future.
