A keylogger is spyware that records what you type - passwords, messages, credit card numbers - and often tracks clicks and screenshots too. Criminals bundle it inside shady installers, phishing attachments, or cracks. For background and cleanup tips, see our keylogger explainer.
Sudden re-prompts for logins or missing 2FA texts
New startup items, browser extensions, or a “helper” you did not install
Odd spikes in network traffic when you are idle
Brief command windows that open and close quickly
Phishing emails and macro-enabled documents
“Free” repacks, keygens, and fake updates
Drive-by downloads from risky sites
Disconnect from the internet to stop data exfiltration.
Run a full anti-malware scan, reboot, then scan again.
From a clean device, change passwords and turn on MFA for email, banking, and cloud.
Check startup items, scheduled tasks, services, and extensions - remove unknowns.
Watch accounts for unusual logins and sign out of other sessions.
Install software only from official sources - avoid cracks and repacks.
Keep OS, browsers, and Office updated and block macros by default.
Use EDR or reputable anti-malware with real-time protection.
Enable MFA everywhere so stolen passwords are less useful.
Consider DNS and web filtering to block malicious sites.
