When it comes to internet security solutions one of the best ways to convince customers – aside from, obviously, protecting computers from malicious attacks – is by offering them the option to try software for free. And Avast definitely aces in that regard. Not only is the company’s Mac antivirus entirely free of charge, but all additional features can be tried out for free either via a 60-day free trial or a 30-day money-back guarantee. If that’s not enough, there are various trial options for other Avast Mac security solutions as well, such as the password manager or the company’s own VPN.
