Smartphone original program folder icon alway missing

[Guest mantis123]

Recently I have found that always a program folder icon is missing instead, a yello file folder icon is on the top the original folder icon. I have to reinstall it and to get the beautiful original icon back, but another program folder icon is changed into a yellow file folder icon. I think there is a virus in my i-mate smartphone, I REALLY is tried to reinstall the program again and again, could anyone help me??? Any way to fix this problem???? Thank you very much.
