Where you download apps from and how you use them plays a critical role in keeping your mobile phone secure.

Malicious apps will try to steal personal information from your phone and can expose your device and data to malware. 

Malicious apps can pave the way for attacks ranging from unwanted pop-up ads to more serious efforts to steal personal and financial data. They can also lock your files and demand a ransom for the key to let you access them again.  

Advertising apps, although often legitimate, can be used to promote other malicious apps, or collect large amounts of data to exploit and sometimes carry out cybercrime.
