Malwarebytes Found Several Trojans—Should I Clean Install Windows 11?

A system restore isn’t a reliable cleanup method for a trojan. Restore points can be infected, deleted, or left with malicious files and settings intact. You can run an offline antivirus scan as an additional check, but with seven detections and uncertainty about what was executed, I wouldn’t rely on scanning alone.

Treat the computer as potentially compromised until it’s wiped. From a different, trusted device, change your email, banking, Discord, and other important passwords, revoke active sessions, and contact your bank if anything unusual appears. Passkeys and two-factor authentication help, but they don’t guarantee that an attacker didn’t already steal a session or credentials.

The safest option after multiple trojans were detected is to back up only personal files you’re confident are safe and perform a clean Windows installation. Malware can hide or make system changes that scanners don’t completely undo. Don’t back up programs, installers, scripts, or suspicious mods; reinstall those from trusted sources after Windows is reset. Before wiping anything, make sure your important files are copied elsewhere and that the backup opens correctly.
