FreeFixer is a free program for the Windows operating system that helps you detect potentially unwanted software that runs on it or has made modifications to it.
You can download the program from its official website where it is available free of charge. You will notice however that a pro version is available that adds a quarantine option to the software. All other features are shared between both versions.
When you start FreeFixer for the first time after installation a scan page is displayed. Before you do anything here, you may want to switch to settings and tools first.
You can enable or disable background scanning under settings, enable the generation of MD5 or SHA256 hashes for files, or disable the upload option when you click on the more info link in the program interface.
Tools on the other hand provides you with access to a tool that you can use to delete files, and a quick link to Microsoft's System File Checker tool which verifies the authenticity of all core Windows files.
Scans take about a minute to complete and display information that look similar to those of HiJackThis. This means first and foremost that the program does not make distinctions between good and bad programs.
It has two safeguards though that come in handy. It will exclude core system files from being shown in the program window, and highlight files from trusted companies such as Apple, Microsoft or Oracle in green.
It is up to you to decide what is problematic or unwanted, and what is not. While that's not that much of a problem for experienced or tech-savvy users, others may want to get help interpreting the results on the official FreeFixer forum.
So what is being analyzed?
As you can imagine, it takes some time to go through the list. What you may notice right away is that Internet Explorer and Firefox are the only browsers supported, while Google Chrome, Opera or even Safari are not in the latest program version.
Each entry is listed with information that you can use to identify it. This includes the file path or Registry path usually, and sometimes also other information such as Class IDs, display names or architecture information.
These help you identify the file or setting. You will also find a more info link listed here which, when clicked on, opens information about the selected file type on the Free Fixer website.
The information displayed here provide you with detailed information including a VirusTotal report.
For files and settings that are not whitelisted, a delete box is displayed by FreeFixer as well. You can use it to remove the file or setting from your system.
A basic example is the removal of startup items from it, but you can remove browser extensions and other files as well using the feature.
Scan results can be saved to a log file. This is helpful if you require assistance in determining what to remove and what not to, and also for safe keeping.
FreeFixer, just like HiJackThis, is a useful tool that provides you with large data sets that you need to go through manually, or ask someone to do so for you.
The program could use support for Google Chrome and Opera to cover all major Windows browsers, but other than that, it is offering extensive information.Advertisement
