Make sure that no other programs are running while you install the antivirus. You will most likely need to be connected to the internet to download additional files and updates.

You have the opportunity to opt out of these changes during the installation process.
Update the program. After the installation is complete, reboot your computer and update the program. The file that you downloaded is likely not the most up to date version, so you will need to connect to your antivirus program’s servers and download the latest updates. Most antivirus programs allow you to right-click on the icon in the System Tray while it is running and click Update. Update your definitions on a weekly basis. Most antivirus programs are set to automatically update. Double check the settings for your program to ensure that you are receiving the necessary updates.
Once you have the program installed and updated, it’s time to scan your computer. This could take several hours, depending on the number of files being scanned and your computer’s speed.
Antivirus programs are most effective when they are automated. Open your antivirus program’s settings and look for the Schedule option. Try to schedule a time when your computer will be on but you won’t be using it. Ideally you should be scanning once a week; scan more frequently if you deal with potentially infected files on a regular basis.
