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?

How to Analyze Your Logfiles No internet connection available? Read this: . In order to analyze your logfiles and find out what entries are nasty and what are installed by you, you will need to go to "hijackthis.de" web page. Just paste your complete logfile into the textbox at the bottom of that page, click "Analyze" and you will get the result. I find hijackthis very usful and easy to use.I have saved that web page to my disk to come back again and again. It is an excellent support. Thanks hijackthis!

A must have, very simple, runs on-demand and no installation required. Essential piece of software.

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.
