* Step one -- are you already infected? It can be difficult for end users to know if they have any malware on their phones, but there are a few factors that can be indicative. Users should regularly check which apps are running. Anything suspicious should be deleted. Indicators that malware is present can also include decreased battery life (because there is something running in the background) or an increase in data use (as the malware transmits data from the phone).

* Step two -- block activity. To prevent premium-rate number scams, it is important to check your bill regularly for anything out of the ordinary or, better still, contact your provider and block this type of number.

* Step three -- prevent infection. There are a number of elements to this that, while not a guarantee, will help minimize malware when used together. Regardless of whether the handset is corporate or personally owned, organizations should encourage their workforce to practice these steps:

• Antivirus software for mobile phones is available to download, however it is argued that it can be ineffective.

• Settings on the phone can be changed to prevent installation of content that isn't from trusted sources.
