My anti virus detects malware in device management / manager and suggests uninstalling it. should I?what I have read and found is its an important part of the phone. I simply can't uninstall it. Is it a serious threat or can I ignore it?and if shouldn't ignore it then what should I do? Save my data and reinstall to factory settings?? I am not very tech savvy so do suggest what should I do? I use an sd card for my data which is mostly pictures.My phone seems to work fine not that I find any issues except that my contact list getting erased partially n then getting restored automatically after couple of days.
