First of all you cannot change your app from being free to be paid for. You'll need to have separate app in BB World. Thus upgrade is not possible.
Second to upgrade an app you don't have to uninstall it. Just start BB World and tap upgrade.
What do you mean by "Customers are not able to uinstall the previous version or even buy latest version"?
And on a side note: what kind of malicious stuff does your app detect? I am just curious - probably I badly need it, can you give several examples please?
