Hijack This
HiJackThis+
HiJackThis+ (Plus) (previously called: HiJackThis Fork v3) is a fork and a continuation of the original Trend Micro HiJackThis by Merijn Bellekom development, once a well-known tool.

At the moment, it is a step-by-step 100% rewritten source code of the original engine, aimed to provide a full compatiblity with the most recent Windows OS and a balance beetween compiling very fast results in logfile and combatting with the most popular malware, inluding the one not known to other antiviruses.

It is made by Alex Dragokas - a lawyer, security observer and malware researcher.

Overview
HiJackThis+ is a free utility for Microsoft Windows that scans your computer for settings changed by adware, spyware, malware and other unwanted programs. Shortly, consider it like Sysinternals Autoruns.

The difference from classical antiviruses is the ability to function without constant database updates, because HiJackThis+ primarily detects hijacking methods rather than comparing items against a pre-built database (signatures). This allows it to detect new or previously unknown malware - but it also makes no distinction between safe and unsafe items. Users are expected to research all scanned items manually, and only remove items from their PC when absolutely appropriate.

Therefore, FALSE POSITIVES ARE LIKELY. If you are ever unsure, you should consult with a knowledgeable expert BEFORE deleting anything.

HiJackThis+ is not a replacement of a classical antivirus. It doesn't provide a real-time protection, because it is a passive scanner only. Consider it as an addition. However, you can use it in form of boot-up automatical scanner in the following way:

Run the scanning by clicking "Do a system scan only"
Add all items in the ignore-list
Set up boot-up scan in menu "File" - "Settings" - "Add HiJackThis to startup"
Next time when user logged in, HiJackThis will silently scan your OS and display UI if only new records in your system were found.
