HijackThis (HJT) is an open source enumerating tool for Microsoft Windows originally created by Merijn Bellekom, and later sold to Trend Micro. The program is notable for targeting browser-hijacking methods, rather than relying on a database of known spyware. It scans a user's computer quickly, and displays browser hijacking locations, showing what entries are there. HijackThis is used primarily for diagnosis of browser hijacking, as uninformed use of its removal facilities can cause significant software damage to a computer. HijackThis does not remove or detect spyware; it lists most common locations where browser hijacking activity can occur. Browser hijacking can cause malware to be installed on a computer.

On February 16, 2012, Trend Micro released the HijackThis source code as open source and it is now available on the SourceForge site.Contents [hide]

HijackThis can generate a plain-text logfile detailing all entries it finds, and some entries can be fixed by HijackThis. Inexperienced users are often advised to exercise caution, or to seek help when using the latter option, as HijackThis does not discriminate between legitimate and unwanted items, with the exception of a small whitelist of legitimate entries, thus allowing a user unintentionally to prevent important programs from operating, which may cause the computer or its peripherals to stop working. HijackThis attempts to create backups of the files and registry entries that it fixes, which can be used to restore the system in the event of a mistake.

A common use is to post the logfile to a forum where more experienced users can help decipher which entries need to be removed. Automated tools also exist that analyze saved logs and attempt to provide recommendations to the user, or to clean entries automatically. Use of such tools, however, is generally discouraged by those who specialize in manually dealing with HijackThis logs: they consider the tools dangerous for inexperienced users, and neither accurate nor reliable enough to substitute for consulting with a trained human analyst.

Later versions of HijackThis include such additional tools as a task manager, a hosts-file editor, and an alternate-data-stream scanner.
Description
HijackThis inspects your computers browser and operating system settings to generate a log file of the current state of your computer. Using HijackThis you can selectively remove unwanted settings and files from your computer. Because the settings identified in a HijackThis log file can belong to both legitimate software and unwanted malware, it is important to use extreme caution when choosing to removing anything using HijackThis.

HijackThis also comes with a process manager, HOSTS file editor, and alternate data stream scanner.
