My father is having problems with his mobile phone. I think that it's a virus infection. Because the problems started when my father opened the phone's Bluetooth. He didn't have any antivirus software installed.Firstly the mobile phone couldn't read incoming messages. There was the sound when a message arrived, but it wasn't possible to view the messages. Now the phone turns off and on automatically. I removed the phone's memory card, and plugged it in my computer. I scanned it with KIS but nothing was found. My questions are: -Is it possible for viruses to infect some internal(not removable) part of the phone? -If yes, how can I install and run a mobile antivirus when the phone is turning on and off by itself?
