Trend Micro HijackThis is a free Windows utility for examining system settings that may have been changed by spyware, malware or other unwanted software. It is aimed at users diagnosing possible infections and people comfortable reviewing technical reports. Rather than identifying each finding as safe or harmful, it records a broad range of browser, registry and file settings for further analysis.
A scan creates a detailed report of system and configuration entries. The report can help reveal unfamiliar changes and gives users a way to inspect what is configured on the computer. Because HijackThis does not distinguish legitimate settings from malicious ones, a scan result is not a list of confirmed threats. Items should be evaluated before removal; deleting a valid entry can affect normal software or Windows behavior.
The utility also provides a selective removal function, allowing users to choose entries they want to remove instead of applying an automatic cleanup to every finding. Its additional tools support manual malware-removal work. This makes the program more suitable for investigation and hands-on troubleshooting than for unattended protection or routine antivirus scanning. Its report can also be useful when seeking help from someone experienced in interpreting system configuration data.
Typical uses include checking for persistent unwanted browser or system changes, reviewing a computer after a suspected infection, and gathering configuration details during manual cleanup. HijackThis can assist with identifying areas that deserve investigation, but it does not replace an up-to-date antivirus product, and a report alone does not establish that a computer is infected. Careful review is especially important before using its removal controls.
Trend Micro distributes HijackThis as freeware. The supplied system support information includes Windows versions through Windows 10, including 64-bit editions; it does not establish Windows 11 support. The utility is a diagnostic aid, so its results are most useful to users who understand registry and file settings or can consult a knowledgeable helper.
