Avast Free Antivirus for Mac is Avast's answer to concerns about how to browse safely. The application is packaged with a brand-new, easy-to-understand graphical user interface, with access to all features available at single click.
The application's onscreen tools are well-organized, and its live graphics enhance the feeling of safety -- you can see that the antivirus software doesn't sleep and is always working to protect you from any viruses circulating on the Web. Avast's free software provides three shields to protect your computer: a file system shield, an e-mail shield, and a Web shield. With all three representing a door to your computer, Avast does a great job of watching these entrances.
However, this comes at a cost, and we don't mean money: as soon as you launch the app, you'll notice a slight drop in your computer's performance, which is due to Avast being at work scanning your entire computer for infected files. Secondly, it affects your browser's performance, as it also scans the pages you attempt to navigate to for viruses through the extensions it installs in Safari, Firefox, and Chrome browsers. We did find its notification feature handy, as it informs the user about its actions, so you'll always know what the software is up to.
Overall, Avast Antivirus for Mac is a nice addition to your Mac toolbox. It's free and very easy to use.
