Hijackthis – Finds Malware, Adware And Other Security Threats

Hijackthis - A Free Utility That Finds Malware, Adware And Other Security Threats

[sc name=”ad_1″]

HiJackThis Fork is a free utility for Microsoft Windows that scans your computer for settings changed by adware, spyware, malware and other unwanted programs.

HiJackThis Fork primarily detects hijacking methods rather than comparing items against a pre-built database. This allows it to detect new or previously unknown malware – but it also makes no distinction between safe and unsafe items. Users are expected to research all scanned items, and only remove items from their PC when absolutely appropriate.

Therefore, FALSE POSITIVES ARE LIKELY. If you are ever unsure, you should consult with a knowledgeable expert BEFORE deleting anything.


  • Lists non-default settings in the registry, hard drive and memory related to autostart
  • Generates organized, easily readable reports
  • Does not use a database of specific malware, adware, etc
  • Detects potential methods used by hijackers

Log analysis

IMPORTANT: HiJackThis Fork does not make value-based calls on what is considered good or bad. You must exercise caution when using this tool. Avoid making changes to your computer settings without thoroughly studying the consequences of each change.

If you are not already an expert, we recommend submitting your case to an online help forum. Here are some suggestions:

Note: currently, only Russian-speaking anti-malware supporting team (e.g., VIRUSNET association) can provide direct analysis of HiJackThis logs in our github ‘Issues’ section. Please feel free to ask help there.
