Her is my view on this application!I can confirme the reg key it uses,is this one: HKEY_CURRENT_USER\Software\Shareaza\ And the installer comes bundled in with Ask Toolbar,its optional-but still not good....I have inspected the main exe file and the code so far look clean....Its based or modified from Shareaza 2.4.0.0 source code!Or it could be a revers engineering of Shareaza 2.4.0.0 directly also!But i have to study the software littel bit moore-then we see!!!
