A Trojan Horse is a type of malware that's designed to look like a legitimate file or legitimate software. It can be used to achieve a variety of malicious goals, including stealing usernames, passwords, or other sensitive information, or deleting or corrupting data.

Monitor website visits to check for any sites that might be associated with malware. Run regular system scans to detect any malicious files or software. Additionally, keep your operating system and security software up to date.

If there are suspicious activities detected on your device, use malware removal tools like anti-virus and anti-malware scanners to search for and destroy any malicious files.
