Should I install Antivirus/Spyware etc. protection. As far as I have been able to find there are Apps that access phone data such as call records, SMS, emails, personal details and phone records etc. While I have been checking the list of what it does before I install them, I was reading that one App originally did nothing but use space on the SD card, a later update introduced network access for adds but also phone records. Many users may not have seen the change and would have allowed access. Are there any other security issues that I need to a aware off? And how should I protect against any threats?
