Hello,
We did not make any copies of the client files, sorry. You can download theme archive from the ThemeForest account. We are sure that it does not include any malware because checked by our team and Envato.
As a rule malware code placed in different files of the WP installation and if you cleaned it by yourself without hosting support then probably you missed something.
The database also could include injections, so, if you are not very familiar with this process it would better to ask experts to clean your WP installation.
Regards
