Malware protection

Avast offers malware scanning as one of the main functions of the applications. However, the scan itself was one of the slowest and took between 45 seconds to a full minute. In addition, Avast Mobile Security and Antivirus enables users to schedule scans whenever the user wants.[4]

Avast also protects users while they browse the web. Avast Web Shield works with the native Android browser, Google Chrome, the Amazon Silk browser, and Boat Browser. The application successfully protects users against malicious and suspicious sites. 

The application was tested by the German independent lab AV-TEST. The scores weren’t as good as Norton Mobile Security and Antivirus, but they are still better than the market average. 

Free Security Features

Avast Mobile Security and Antivirus for Android offers users a number of free security and privacy features including: 

  • Call Blocker
  • App Permissions
  • Anti-Theft
  • Firewall 

Even though the number of free features is impressive, some of them are not reliable, for example, call-blocker does not work and the anti-theft feature is not effective at all due to connectivity issues with the web portal.  

Impact on system performances

The performance impact of running Avast Mobile Security in the background is relatively low. However, during the scans, it slows down the system noticeably. 

Avast Mobile AndroidUser interface

The most options in the application can be found without scrolling. Even though the design looks modern and simple, ads in the free version get very annoying. 

The final verdict

Avast Mobile Security and Antivirus for Android is one of the most customizable and comprehensive security solutions available on Google Play. The application offers award-winning malware protection which is not far from perfect. Hoverer, some security, and privacy features are not reliable and do not functional how they should be. 

Malware protection Solid
Additional features Many, however, not reliable
Impact on system performances Mediocre
User Interface Easy to navigate, but appearing adds can get annoying

To Summarize

In addition, free versions of both security application also include many features at both applications. However, when it comes to efficiency,  some of the Avast Mobile Security additional functions are not reliable and do not work how they should.
