Add your signposting title here… What is a virus?

Viruses are a form of malware. Short for ‘malicious software’ that affects PCs,tablets and phones. Viruses typically undertake unauthorised activity and attempt to steal, encrypt or delete your personal data.

Some malware has been developed to specifically target mobile devices, with additional capabilities which enable the monitoring and theft of text messages and the making of premium rate phone calls.

Mobile malware most often presents itself as genuine apps, but are in fact malicious clones which exist outside of official app stores or sometimes as apps you may intentionally seek out that unlock certain capabilities or functions within other apps (unlocking game features etc.) again, most often found outside of the genuine apps store, typically referred to as unknown or unofficial sources.

What can mobile viruses do?

Amongst other things, malicious mobile apps can:

  • Install itself on your device without your knowledge, typically within an app that looks benign or by copying another app's look and feel
  • Steal personal data such as contacts lists, local documents and files, or via more direct overlays and prompts for information, which can appear legitimate, but will communicate directly with fraudulent third parties
  • Encrypt your device and demand a ransom before you are able to use your phone again (ransomware)
  • Make premium rate phone calls, steal data or send premium cost SMS messages
How to avoid viruses
Don't download apps from unofficial or unknown app stores

Don't download apps from unofficial or unknown app stores

You should only download apps from an official app store. Always ensure that the permissions match your expectations of what the app would be expected to do.


Google and Apple monitor their own app stores, and these are therefore sources which you can have a much higher level of trust in.


Be aware of attachments and download prompts

Be aware of attachments and download prompts

Efforts to spread malware can be triggered via the delivery of malicious attachments (SMS or email) or via spurious prompts on webpages, which may state your phone is at risk and you must install an app to resolve. As a rule of thumb if you didn't begin with the intention to install an app don't.

Don’t tamper with the security of your device

Don’t tamper with the security of your device 

Think carefully before jailbreaking or rooting your device. We strongly advise against doing this as it may weaken the security of your device and expose you to additional risks.


Jailbreaking/rooting is when you change the security settings of your phone to allow you to download 'unofficial' apps that are not available from the app store.

Keep your device updated

Keep your device updated

Mobile Network Operators and phone manufacturers such as Apple, Google and Samsung will make updates available for your device, which typically include functionality enhancements, but critically include security updates.


These are common for both Android and iOS operating systems and whenever made available , you should ensure that you have the latest software installed. The same is true for apps on your device, which will be updated by their developers for similar reasons. Failure to install security updates will leave your device more at risk from security vulnerabilities.

Anti-virus and security apps can keep you safe by:

  • Scanning your phone to identify malicious apps
  • Scanning any apps you download before they are installed to identify malicious applications or functionality.
  • Removing malware from your phone

iOS is Apple’s Operating System. iOS app installations are more restrictive as compared to Android with additional layers of protection and vetting prior to app release within the App Store. As a result there are less anti-virus style applications available for iPhones and iPads.


As with Android operating systems, make sure you only download from the official App Store and install operating system updates when available to keep your phone protected.
