Like Windows before it, the 'open' and widely popular Android system from Google has a weak security system that makes it prone to infection from dangerous malware (more than it affects iOS users). We reveal the best antivirus apps for both Android and iOS.

Do you need Android antivirus?

The idea of installing security software on a smartphone might seem like overkill, but there are plenty of good reasons to consider doing so.

Anyone – fraudsters included – can submit apps to the Google Play Store without pre-approval, and apps can also be downloaded and installed from a wide range of other sources.

That means Android users face a greater element of risk than those with iPhones or Windows Phone handsets, who can only install apps that have been properly pre-vetted for safety.

Nevertheless, every user is at potential risk from malware and physing emails and ads - so no matter the platform you're on, it's good to have a mobile antivirus program installed.

The more open nature of the Android operating system makes it more susceptible to the kind of malware that we've grown accustomed to dealing with on Windows PCs. Although the scale of the Android malware problem isn't yet as bad as it is on Windows PCs, it remains a threat all the same.

The security software test lab Av-Test, has millions of different pieces of Android malware in its database – malware that is typically used to steal your valuable personal data from your phone without your knowledge.


Yet, even if you're careful about what apps you install or which websites you visit, there are other strong motives for installing a security suite. Such security apps routinely include anti-theft features, for example.

Contrary to the name, they won't prevent theft but they may allow you to lock or wipe the data from your stolen handset. Some even include features that allow you to take photos or audio recordings of the thieves.

If you've merely left the phone lying in a bar or restaurant, the anti-theft features can be used to locate your handset, and display a message on the lost phone's screen, providing instructions on how to contact you, in order to return the handset.

Call blocking

Another useful feature commonly found in security suites is call blocking. If your mobile is constantly plagued by nuisance calls or spam texts, you might be able to block the callers so that they don't interrupt your day. But this won't work when you're being plagued by pre-recorded calls hawking PPI refunds and the like, when the caller number is Unknown or Withheld.

Some apps include schedulers in their call-blocking facilities, so you can divert all calls from the office to voicemail at evenings and weekends, for example.

App managers

Some suites also include app managers that allow you to password protect access to the web browser – invaluable for parents who routinely hand their phone over to children to play games and worry that they might stumble into something they shouldn't, or run up horrendous bills by purchasing apps.

Backup facilities

Less useful are the backup facilities found in many of these suites. Some merely back up contacts, which certain apps already support the feature when you sign in with your Google or Apple account, while others only offer a tiny amount of space to store your photos and files.
