Update the antivirus program if prompted: Antivirus software automatically updates itself with new virus definitions and security features.Subsequent scans usually take only a few minutes. The software will let you know how long the scan will take and if you can use your computer in the meantime.
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.
If you have a lot of files on your computer, the initial scan could take an hour or more. 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.
