Remember that Python keylogger I showed you how to build? If you haven’t read that one yet, check it out first  Keylogger-app-logic  ,  python-keylogger-script – this post will hit harder once you see how a simple script can silently record every keystroke. That project was all about red team cybersecurity skills – thinking like an attacker. But today, I’m switching sides. I wrote a lightweight Python antivirus script that hunts down and kills keyloggers running in the background. No heavy antivirus software, no flashy UI – just clean Python code doing the job. I wanted to keep it simple and practical: Detect any suspicious process connected to a keylogger. Kill it immediately. Keep scanning so nothing slips through. This is perfect for ethical hackers, cybersecurity students, or developers testing malware in a safe lab setup while building their blue team defensive skills .  Disclaimer This blog is human written and I use AI tools...
