ClamXav is an antivirus created for Mac. This utility helps you remove various types of malware threats from your computer, has simple to configure settings, and immediately gets the job down without slowing down the performance of your Mac in the process.
You need to install an additional tool before scanning your system for malware threats. Once the utility is installed on your computer, you can select the folders you wish to scan and wait for the results. The application immediately reveals the found information in the same window.
In the Preferences panel of the program, you will find plenty of useful options. For example, you can configure the app to avoid scanning files with certain extensions or names. Furthermore, the utility lets you choose which folders from your Mac to monitor and automatically scan.
Another great thing about this tool is that you can schedule scans if necessary.
Still, ClamXav can't compare to the other antiviruses, and I don't think it's worth buying it unless you're on a really tight budget.
