Running two antivirus products on the same computer can cause system instability and degraded performance. It is important that any previously installed antivirus software is uninstalled from your system before installing your ESET security product.

For your convenience, as typical uninstallation using the Windows removal tool (Add/Remove Programs) is often insufficient,  removal tools* for common antivirus programs can be downloaded by following the links below.

1. Click the link associated with the antivirus software currently installed on your system and follow the prompts or instructions on the website.
    
2. After uninstallation is complete, you will need to restart your computer. You may then proceed with installing your ESET security product.

NOTE: For additional help downloading and installing your ESET security product, view our installation video tutorials. The controllable videos take you step-by-step through the download and installation process.
