Download an antivirus application for your Mac. Many applications are available online, including popular options such as Sophos Anti-Virus, iAntiVirus and Avast! Mac Edition, and some offer free trial versions. Save the installation utility on your desktop for ease of use.
Double-click the downloaded installation utility and accept the default installation options. Launch the program when the installation is complete.
Update your chosen antivirus application to ensure it has the most recent virus signatures. These signatures are small code snippets that allow the application to recognise a virus when it finds one.
Run a full system scan once the update is complete. This scans all files on all hard drives in your computer. Any detected viruses are listed in a summary screen when the scan is complete. Delete all malware detected with the scan.
Schedule your antivirus application to update and scan automatically. Make sure to schedule the tasks for a time when your computer will be running, and have them run at least twice a week to keep your system clean.
