HijackThis is a free utility that generates an in depth report of registry and file settings from your computer. HijackThis makes no separation between safe and unsafe settings in its scan results giving you the ability to selectively remove items from your machine. In addition to this scan and remove capability HijackThis comes with several tools useful in manually removing malware from a computer.

IMPORTANT: HijackThis does not determine what is good or bad. Do not make any changes to your computer settings unless you are an expert computer user.

Advanced users can use HijackThis to remove unwanted settings or files.

Source code is available on the SVN server under Code and also as a zip file under Files.

I find the HijackThis SCAN to be useful in checking out my system, but HijackThis cannot find my internet connection for some reason so I can't do an AnalyzeThis. I am not infected. I'm just using HijackThis to check on the processes/drivers I am loading at boot time. Any suggestion on helping the software locate my internet connection?

"No internet connection available" problem occurs after selecting 'Analyze This", even in safe mode. Since an internet connection is actually available, this message does not provide any useful information. What the actual problem is remains unresolved, even after going through a page of google results concerning this obviously incorrect error message. Anyone know of a program I can use to troubleshoot HijackThis?

HiJackThis is very good at what it does - providing a log of what's on your Windows computer that could potentially be a hijacker, and removing items you select. It requires expertise to interpret the results, though - it doesn't tell you which items are bad. Non-experts need to submit the log to a malware-removal forum for analysis; there are several available. The AnalyzeThis function has never worked afaik, should have been deleted long ago.

"No internet connection available" When trying to analyze an entry. That renders the newest version (2.0.4) useless

Can you please take us off your blacklist? I mean we, the Syrians, need proxy to download your product!! Isn't enough the bloody civil war we're going through? What's the point of banning us from using your free app? I always recommend it! Thank you.

HijackThis keeps giving me O15 error issues after a scan with 'https and http are in the my computer zone, not internet zone.' on windows 7. It does not delete them, they keep reappearing after a scan. I think it may be due to ProtocolDefaults missing from my version of 7, which should be at HKEYCURRENTUSER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\ProtocolDefaults, so the program believes I have an issue. It sounds like the program is out of date. Every other location in my registry with ProtocolDefaults shows http and https with a value of 3, which is the internet zone. HiJackThis may be out of date and not for use with 7, if I dont have missing values.
