The first scan took 1 minute and 37 seconds, which is a bit longer compared to other antiviruses on this list. After the initial scan, other scans were much faster, around 30 seconds. I like that Avast lets you decide how to deal with malware. After a scan, you’ll get a set of three options: Remove, Ignore, and Not malware, which requires you to write a report. Avast also flags actions you have not taken, such as disabling Web Shield, as a core issue. Avast is an ideal free option for Android users who want a suite of online security features and malware protection.
