Common Antivirus Removal Tools

Uninstalling antivirus software through the standard Windows Add/Remove Programs (or Programs and Features) does not always remove everything. Leftover files, registry entries, drivers, and services can remain on the system, potentially causing conflicts with a new antivirus installation or other software.

Most antivirus vendors provide dedicated removal tools that are designed to thoroughly clean up all traces of their products. Below is a list of official removal tools from major antivirus vendors.

Official removal tools

• Norton Antivirus / Norton Internet Security — Norton Remove and Reinstall Tool
• Kaspersky Antivirus / Kaspersky PURE — Kaspersky Removal Tool
• BitDefender — BitDefender Uninstall Tool
• ESET NOD32 — ESET Uninstaller
• Trend Micro — Trend Micro Diagnostic Toolkit
• AVG Antivirus — AVG Clear / AVG Remover
• McAfee — McAfee Consumer Product Removal Tool (MCPR)

When to use a removal tool

• When switching from one antivirus product to another and the standard uninstaller did not fully remove the previous product.
• When you see error messages about conflicting security software during a new antivirus installation.
• When antivirus services or drivers continue running after uninstalling through Windows.

Tip: Always restart your computer after running a removal tool to ensure all changes take effect. It is also good practice to run the removal tool in Safe Mode for the most thorough cleanup.
