Keylogger malware doesn't wreak havoc on your system. Instead, it sits silently, capturing your information and spying on your activities. Keyloggers can steal your account names, passwords, and banking information without ever alerting you—which is why I periodically check my computer for this nasty type of malware.
Look for Unfamiliar Software Installed on Your Device
If you suspect a keylogger is installed on your computer, you should first check the Windows Task Manager or macOS's Activity Monitor and look for any unfamiliar programs running in the background.
If you see an unfamiliar app, search for it on Google to see what kind of app it is. Some of the most common keyloggers include Spyera, HoverWatch, TiSPY, iKeyMonitor, and XNSPY. You’re unlikely to see the names "Spyera" or "XNSPY" in Task Manager or Activity Monitor. These apps often hide behind generic or fake system process names to avoid detection. But if you see any process that seems unfamiliar, especially one using high memory or CPU, it's worth investigating.
Remove Apps You Didn't Install on Your PC
The steps above will only stop the keylogger from running, but it's still installed on your system. So, to remove a keylogger completely, on Windows, go to Settings > Apps > Installed apps and search for the program you just deactivated. When you find it, click on the three-dot icon next to the app and choose Uninstall.
Follow the corresponding instructions to remove the app. Once you're successful, restart your computer to ensure it's completely removed. You can also review all the other installed apps on your system to ensure that you don't miss any unwanted malware lurking in your system.
Use an Antivirus to Scan for Malware
Unfortunately, uninstalling the suspect program does not mean that your computer won't get infected again or even that you've fully removed the keylogger malware. That's why you should install an antivirus or security suite to protect your PC against them, including keyloggers.
Look for Unfamiliar Hardware
Although most people think of malware as software installed on their computer, some keyloggers intercept the signal between your keyboard and PC. This could be through an adapter that sits between your keyboard and CPU, or it could also be through a fake USB cable.
So, to protect yourself, you need to periodically check your computer ports to see if there's an unfamiliar adapter attached to them. You should also be wary of fake cables, as some USB cables harbor malicious hardware.
The Nuclear Option: Reset Your PC
If, after all these steps, you still feel that your computer is being targeted, the nuclear option is to reset your PC. If you do this, pick the Remove everything option to ensure nothing is left behind. This may be inconvenient, as everything is cleared from your computer, but at least you're guaranteed a clean slate with your computer. If you use cloud or external storage, you should also check your stored files to ensure that no malware is lurking in your archives. You might also consider a clean Windows install, where you wipe your drive and start fresh.
Keyloggers are stealthy but not unstoppable. By combining vigilance with regular scans, secure browsing habits, and occasional hardware checks, you can stay one step ahead. When in doubt, a full reset gives you the clean slate you need.
