A trojan can remain hidden in a computer even after antivirus scans, reappearing upon Windows restart. Experts explain why some infections are difficult to remove and outline steps to protect personal data and online accounts. Dangerous programs may operate unnoticed, with some using persistence mechanisms to reinstall infected components automatically. Disconnecting from the internet, checking scheduled tasks, and controlling startup programs are crucial steps. Running Microsoft Defender Offline can help detect threats, while changing passwords and considering a clean Windows reinstall may be necessary if issues persist.
