Trend Micro Hijack This is a cleanup utility that detects browser hijacking issues and attempts to solve them by deleting the registry entries that contain the malware.
Unlike similar software, Trend Micro Hijack This does not rely on a database of the latest malware out there, but instead it tracks the modifications performed in your browser and allows you to undo it. Utmost care is required when removing the adjacent registry entries, since the adjustments are sometimes irreversible.
The user interface does not sport any visual incentives, but it’s straight-forward and intuitive. From the main menu you can perform a system scan and optionally save the results to a log file, view the list of backups, open the miscellaneous tools section or open the online HiJackThis QuickStart.
System scans are performed extremely fast and at the end of those checks, a list of detected issues is displayed, with the possibility to fix those problems. An option to select all the files at once is not available, but instead, you need to perform the selection manually.
Before repairing the checked files, it is highly recommended that you do backup your registry or create a system restore point. On the upside, the application offers you some pieces of information on every item and also enables you to add them to a ignore list. Once the detected issues are fixed (which can either mean repaired or deleted), your computer may need a restart.
From the 'Miscellaneous Tools' section you can generate a startup list log, open process manager or the hosts file manager, delete a file on reboot or an NT service, open ADS Spy or trigger the 'Uninstall Manager'.
In conclusion, Trend Micro Hijack This is a detection tool that scans your computer registry and identifies unusual behavior in your browser. Since it can perform irreversible changes to your computer, it needs to be handled with care, preferably by advanced users.
