Many antivirus apps offer additional features that can increase your smartphone’s safety. Some of these features include a password manager that protects your login credentials, VPN functionality for enhanced privacy and security and tools to assist in locating or remotely wipe stolen phones.

The majority of antivirus programs will test your phone on a regular basis to check for malicious software signatures that could be causing the problem. They typically run these tests according to a schedule you decide to set, and will notify you of any dangers. They also check to see if you are connected to a network that is not secure that could expose your data to hackers.

Certain antiviruses might have additional features, like anti-theft or a call blocker, depending on the service provider. Kaspersky is one of them. It offers a feature that will take three pictures of the person who is trying to gain access to your device. It also permits you to wipe or lock it remotely. Other companies have system tune-up features that can clear up junk files and increase the speed of your device while others include a tool that can warn you about unsafe applications or settings.

A good way to evaluate how well a service protects your phone is to look at how it performs in the security scores of independent testing labs. Some of the rankings are based on the amount of threats that are detected while others look at things like how quickly the service identifies threats and then eliminates them. Some companies also go beyond the norm, providing features like an unconditional money back guarantee as well as 24/7 customer assistance.
