Can Trojan detection be performed in safe mode?

Yes, Trojan detection can be performed in Safe Mode, and it is often more effective in this environment.

Explanation:
Safe Mode is a diagnostic startup mode in Windows (and similar modes exist in other operating systems) that loads only essential system files and drivers. Many Trojans and malware rely on third-party services, startup items, or non-essential processes to function or hide. When the system boots into Safe Mode, these background components are typically disabled, making it easier for antivirus or anti-malware tools to detect and remove malicious software that might otherwise remain hidden in normal operation.

Example:
Suppose a system is suspected of being infected with a Trojan that modifies browser settings or steals credentials. Running a full scan with a trusted security tool (like Windows Defender or a third-party antivirus) in Safe Mode may reveal the Trojan because:

  1. The Trojan’s associated startup entries or services are not loaded.
  2. The malware has fewer opportunities to interfere with the scanning process.
  3. The security tool can access system files and registry entries that might be locked or obscured in normal mode.

Recommendation (Cloud-related):
For enhanced protection, especially in enterprise environments, consider using a Cloud-based Endpoint Security Solution (such as Tencent Cloud’s Host Security service). These solutions provide real-time threat detection, including Trojan identification, and often include features like behavioral analysis and automatic remediation. In cases where local Safe Mode scans are insufficient, cloud-based security platforms can offer deeper insights and centralized management across multiple devices.

Additionally, Cloud Backup Services (like Tencent Cloud’s COS or Backup Services) ensure that critical data is protected, allowing for safe recovery if a Trojan causes significant damage. Regular backups stored in the cloud can help restore systems to a clean state without paying ransomware demands or losing important files.
