The setup file should have an .exe file extension. If you downloaded your antivirus program the setup or install executable file will appear wherever the downloads are saved. * Follow the instructions of the antivirus setup process to begin installation. You will likely have to agree to a terms of use and press "Next," several times after reading screens of information before installation will begin. * Wait for the installation to complete, and then restart your computer. The software can be configured to run and update automatically or at a certain time the software setting.
