WARNING: Because this is a security removal tool, many fake downloads exist. Cybercriminals often upload fake 015-ctrremove.exe files that contain actual ransomware. Do not download from pop-up ads.
Before you hit the download button, it is critical to understand what you are fighting against. The "015-CTR" (often appearing as 0x015ctr or 015-ctr in registry keys) is typically a Browser Policy Hijacker.
Unlike a virus that corrupts files, this tool primarily attacks your web browsers (Chrome, Edge, Brave, or Opera). It installs a malicious "Managed by your organization" policy.
Ensure Chrome, Edge, Firefox, and Opera are completely closed via Task Manager (Ctrl + Shift + Esc > End task on all browser processes).
Your antivirus might flag the removal tool as a "HackTool" because it manipulates registry permissions. Add an exclusion to your antivirus for the Desktop folder, or pause real-time protection for 15 minutes.
This step is crucial. The changes made by ctrremove are applied during the startup process.
