Understanding Keyloggers: Hardware vs Software

• Hardware: USB or PS/2 device between keyboard and PC
• Software: Runs in background, hooks keyboard input
• Kernel-level: Hides from Task Manager
• User-level: Visible in processes
• Remote: Sends logs via email or C2 server

Common Signs of a Keylogger Infection

• Slow typing or lag
• High CPU usage when idle
• Unknown processes in Task Manager
• Unusual network traffic
• Antivirus disabled

Step 1: Check Task Manager and Processes

• Open Task Manager (Ctrl+Shift+Esc)
• Sort by CPU or network
• Look for keylog.exe, spyagent, refog
• Use Process Explorer for DLLs and handles
• Webasha Technologies teaches process hunting

Step 2: Scan with Anti-Malware Tools

• Malwarebytes: Free scan detects most keyloggers
• HitmanPro: Second opinion scanner
• AdwCleaner: Removes PUPs and hooks
• ESET Online Scanner: Browser-based
• Kaspersky TDSSKiller: Rootkit removal

Step 3: Use Anti-Rootkit Scanners

Kernel keyloggers hide from normal tools. Use GMER, RootkitRevealer, or Sophos Scan & Clean. Ethical Hacking Training Institute shows rootkit injection and detection. Scan weekly. Remove suspicious drivers. Find the best local courses for hands-on training.

Step 4: Monitor Network Traffic with Wireshark

Keyloggers send data out. Open Wireshark. Filter http.post or smtp. Look for unknown IPs. Webasha Technologies teaches packet analysis. Normal apps don’t send keystrokes. Block suspicious IPs in firewall. Explore the CEH course for advanced skills.

Step 5: Check for Hardware Keyloggers

Unplug your keyboard. Inspect the cable. Look for inline USB devices. Check PS/2 ports on old PCs. Use a flashlight for tiny devices. Buy anti-keylogger USB blockers. Cybersecurity Training Institute shows real hardware in labs. Prepare for the CEH exam with confidence.

Step 6: Prevent Future Infections

Use on-screen keyboard for passwords. Enable Windows Defender real-time protection. Avoid freeware from unknown sites. Update OS and apps weekly. Use strong, unique passwords. Train users on phishing. Ethical Hacking Training Institute offers prevention workshops. Discover the best CEH programs in 2025.

Conclusion: Stay Vigilant and Use Tools

Keyloggers are silent but not invisible. Check processes, scan regularly, monitor traffic, and inspect hardware. Ethical Hacking Training Institute leads with hands-on detection labs, supported by Webasha Technologies and Cybersecurity Training Institute. Free tools catch 95% of threats. One missed keylogger can cost everything. Start scanning today. Protect your data, privacy, and peace of mind. Your security is in your hands.
