a-squared HiJackFree Description

a-squared HiJackFree is a detailed system analysis tool which helps advanced users to detect and remove all types of HiJackers, Spyware, Adware, Trojans and Worms. Manage all types of Autoruns on your system, Explorer and Browser plugins (BHOs, Toolbars, etc.). running Processes and their associated modules, control all Services, even those Windows doesn't display, view open ports and the associated listening processes, edit the hosts file, manage installed Layered Service Providers (LSPs) and analyze the system configuration with using our live online analysis.

Feature Overview

Like the Windows Task Manager, the a-squared HiJackFree Processes section lists all running processes. But additionally it shows tons of useful information at the details pane. File properties, loaded modules, online information and process details that indicate whether the program runs as a service, was started by an autorun entry or opens TCP and UDP ports.
Open Ports

Open TCP and UDP Ports

The Ports section of a-squared HiJackFree shows all local open ports. An open port means that there is a process running which listens on the port number for input from outside.

The Ports Manager shows also the processes which listens on the ports so you can quickly see which processes must be shut down to close a specific port. You can kill a process and put it to quarantine for a later restore if needed.

Autoruns

View and edit all autorun entries. More than 30 different autorun locations are displayed and can be edited as well. Beside the default registry autoruns of the current user (HKCU) and all users (HKLM), a-squared HiJackFree also shows autoruns in files like win.ini, system.ini, autoexec.bat and config.sys. Additionally it lists all programs which are automatically run by the autorun start menu folder.

Autoruns can be deactivated temporarily or removed permanently.

The tricky autoruns cover all locations of the registry which are not mainly used to autorun files, but can also be used to start processes like the default screensaver path and others.
Services

Windows Services

With the included Service Manager you can easily see which services are installed and started. Additionally to the Windows Service Manager it shows the full path to the executable service file in the list to help identifying potential harmful services quickly. It also lists services that are not shown in the Windows Service Manager

Others

Explorer- and Browser-Addons

The Addons section of a-squared HiJackFree allows you to view and edit plugins and addons of the Windows Explorer and Internet Explorer. Addons are mainly Browser Helper Objects (BHOs) which extend the functionality of the browser or additional Toolbars.

LSP Protocols

The LSP section shows all installed Layered Service Providers which are some kind of network drivers. Some spywares use LSPs to place ads on transferred website files you view with your browser.

Hosts File

The Hosts file contains the mappings of IP addresses to host names. This file is loaded into memory at startup, then Windows checks the Hosts file before it queries any DNS servers, which enables it to override addresses in the DNS.

You can use the Hosts file to redirect ad network server names to localhost to avoid ads on websites. Another 'feature' of the Hosts file is used by worms. Many of them use that file to redirect all requests to websites of Antivirus companies to localhost to avoid removal of the worm.
Active-X

The Active-X section shows all installed Active-X modules (DLLs) on the system. The list shows invalid references which can be removed.

Quarantine
When removing Malware, you may be in a situation where you are not completely sure if a program is really malicious or not. In such cases it is useful to remove a specific file or autorun, but keep a backup copy at the quarantine for a later restore. Check the "Save Backup" option when killing and removing a task at the Processes or Ports lists.

Online Analysis

The a-squared HiJackFree Online Analysis is a very powerful helper feature to see quickly which autoruns, processes, addons or open ports are harmful. You can click the "Refresh Online Data" button to get the online analysis directly at the program or you can also click the "Online Analysis" button at the right top of HiJackFree, to see a combined analysis web page. There a new brower window comes up with a detail analysis of your system configuration. The report is stored so you can also tell the web address of the report to specialists if needed.
