Online HijackThis analyzers DO NOT always identify all the malware or all the files properly. They sometimes list legitimate files as bad and bad files as legitimate. Although these sites are open to the public, the user needs to know what they are doing and how to research the displayed log entries before using the original HijackThis application to fix anything.
HijackThis is an advanced tool that requires advanced knowledge about the Windows Operating System. Most of the log entries are required to run a computer and removing essential ones can potentially cause serious damage such as your Internet no longer working or problems with running Windows itself.
HijackThis is an enumerator and similar in some respects to a registry editor program which displays areas of the Windows registry where the majority of Viruses, Trojans, Spyware, Adware, and Malware reside. HJT will scan certain areas of your system and then create a log to help diagnose the presence of undetected malware in these known hiding places. It then relies on experts to interpret the log entries [the areas of the registry that it displays and all running processes in Task Manager at the time the log was created] and determine what needs to be fixed.
And just because you "fixed" something with HJT, that does not mean you have a clean system. The "Fix" button in HJT does NOT remove any malware but rather it removes the associated registry entry. Having HJT "Fix" listed entries in a log does not complete the cleaning process. There are specific files and folders which must be deleted afterwards. HJT does NOT delete them.
Futher, removing entries in HJT before the problem is properly identified can make the malware undetectable to other detection and removal tools. HJT this should only be used to clean up the entries left behind, after you have properly removed the malware.
If you do not have advanced knowledge about computers you should NOT fix anything using HijackThis based on information provided in any of the HJT online analyzers without consulting a expert as to what to fix. If you choose to fix anything by yourself, you do so at your own risk.
